I've made a simple 3D cube model in Blender and placed it so it intersect with the part I want to print I've set the "mesh type" of that cube to "don't support overlaps" for that.
I've tried using "Mesh fixes: disable Union Overlapping Volumes" and the "Merge meshes" option, but the merge aligns the cube origin and the model origin which I don't want. Note: If you need to print supports, then in step 2 select "Modify settings for infill of other models" instead of "Normal Model" , and in step 6 also select "Add Support" and any other support related parameters you may need. However, Cura needs at least one "Normal Model" to slice, so to fool it you need to also another Cube as "Normal Model" with the parameters of step 4 somewhere else in your build plate it won't really print.
The most recent versions of Cura cannot do that for you. This is a removed feature or better said: not ported from the old application to the new application , so installing an older version of Cura may work for you. Alternatively there are many more pieces of free software that can do that for you. MeshMixer or the Slic3r application can do that for you. This video shows a demonstration how to do that. I don't know if this helps but download blender 3d, install expoert your models as stl import as stl file enter into edit mode with tab key and delete everything else export as stl maybe would have to set the scale to On Tinkercad, you can import your stl and add "subtraction" cubes, and merge them with the parts you don't want printed.
Fixed crashes with some models on SLA hole drilling. Fixed "out of print bed" indication for objects partly below the print bed. Improved fuzzy skin options wording "walls" instead of "perimeters" , , thanks nsheridan. Fixed confusing cooling hint when min and max fan speed are equal Fixed variable layer editing disabled with raft enabled, this was a regression wrt. Fixed paint on supports showing through model in certain orientations Multi-material painting tool: Fixed incorrect propagation of bottom surfaces with objects partially below print bed Fixed spurious "Supports print better with detect bridging perimeters" enabled on application start-up Fixed incorrect estimated print time on G-code horizontal slider for MMU prints There is no official dark mode support for Win32 controls by Microsoft.
We worked hard to skin Win32 controls to simulate dark mode, however the skinning did not quite work for some controls and some of the skinning is now broken again on Windows Contributors h-2, jschuh, and nsheridan. Assets 10 PrusaSlicer AppImage Improvements with respect to PrusaSlicer 2. Instead, the events are added into the main stack. When the painting tool is closed, all the snapshots taken during painting are compacted into one.
The new 'Slicing finished' notification automatically fades out after 2 seconds The triangle mesh simplification dialog newly allows to render the model in wireframe view, which helps to better asses the achieved mesh complexity and decimation rate. Bugs fixed, reported for PrusaSlicer 2.
Repeated loading and saving gradually increased size of 3MF files containing multi-material objects or objects with modifier meshes , slicing some models was broken and some models were positioned incorrectly in Z The "inflated" 3MFs generated by alpha2 are now being shrunk back when loaded and saved again with 2. Fixed import of AMF files, also broken in 2. The G-Code reader did not process G28, M and M correctly, leading to issues such as shifted models in the preview.
This was a regression due to G-code parser speed up Standalone G-Code Viewer was modifying access times of G-code files loaded. This was a regression with respect to PrusaSlicer 2. SLA resin material config option 'Correction for expansion' was not applied correctly, namely the Z correction was applied to Y axis Fixed possible crash when an object was deleted with the simplification gizmo active. First layer support expansion was not applied when printing without raft.
This was a regression due to support refactoring in PrusaSlicer 2. This results in significant improvement of performance: The total slicing time is now 2x to 4x shorter, higher speed up is achieved on high-end CPUs The G-Code coordinates are newly exported without emitting the leading and trailing zeros, which makes the G-code a bit smaller.
While the new G-code conforms to standard , it may not be consumed by some non-conforming applications Bottom status bar was removed and replaced by notifications showing progress of slicing and the "abort slicing" button. This also solves the Windows 10 dark mode issue, where we were not able to adjust status bar colors We added AMHook.
Windows specific: Several function calls that might have been considered suspicious by anti-virus software were replaced by alternatives. This should lower the probability that PrusaSlicer will be reported as a potential threat. The G-code preview settings at the bottom of the Preview screen are no longer resetted to their defaults after each slicing Windows specific: 'Fix by Netfabb' can now be used on several objects at once.
Place on face no longer unifies rotation of multiple instances around their Z axes to the same angle. The new "Tip of the day" notifications can now reference menu items.
We use it to activate the "Configuration Snapshots" dialog from a "tip of the day". When navigating to a configuration option from the Search dialog, the option's input field gets focus automatically The dialog asking about unsaved changes is now shown in all scenarios when some changes in presets would be lost When the "Reload from disk" action was called on an object for which only the source file name, not the full path to the source file name was known, PrusaSlicer used to always ask the user to look up the source file location manually, while newly PrusaSlicer searches for the source file next to the active project file before asking the user for help.
Bugs fixed with respect to PrusaSlicer 2. This bug was introduced between 2. It is now possible to use Backspace to delete selected items at the object list. Delete and Backspace should now be equivalent in all contexts. The reason that Backspace is used as an alternative to Delete is that some laptops do not have the Delete key at all some Macs, Chromebooks.
Fixed a rare error preventing slicing of specific models Fixed color of objects in preview for SLA printers. Until now, the color of the last filament selected in FDM mode was used. When printing with a wipe tower, all objects are required to have the same variable layer height profile. The test for this constraint was buggy and it sometimes allowed incorrectly the slicing to continue, leading to cryptic error messages later on.
This is now fixed. When slicing was finished while the user was moving the object in the scene, it would reset the object's location. This was happening mainly with the background processing enabled Selection rectangle in SLA support points editing mode did not work reliably when the object was rotated or scaled The view settings combo boxes had incorrect layout the first time they were opened.
Windows specific: Under certain circumstances, a system text edit box unintentionally appeared in the right panel. Fixed possible crash in the new triangle mesh simplification tool when the required number of triangles was too small. Fixed a crash after deleting an object when simplification preview was shown. Painted seam was broken on vertical surfaces, while it worked in PrusaSlicer 2. Fixed crash when enabling visualization of tool change markers in preview Fixed crash when importing gcode generated with Simplify3D and switching to tool view.
Ajusted the wording of "Compare presets" pop-up windows showing differences in multi-line texts Toolpath width in G-code Preview was clamped to 1 mm, which did not work for large nozzle diameters. Fixed several drag and drop issues in object list, which appeared when some of the new rows informing about painted supports, painted seems etc. Fixed inconsistencies of selection in scene and the object list. Fixed deleting volumes through the right panel with the new "Paint-on supports", etc.
When supports are turned on with 'Detect bridging perimeters' disabled, a dialog box offering to turn it on is opened. From now on, this dialog does not have a 'Cancel' button which was confusing and requires strictly 'Yes' or 'No'.
Print setting changes were not applied to all instances if one of the instances was rotated Fixed crash when support patern spacing was set to zero With the settings shown in a floating window, the Search did not bring back the Settings floating window if it was was minimized Windows specific: Combo-box with preset names was too narrow with the new "Settings tab as menu items" enabled G-code Preview did not update when switching to the G-code viewer for the first time after automatic background processing completed slicing Double slider was sometimes captured after certain mouse click combinations and could be moved even after the pointer no more over it.
Fixed endless loop in raft generator, which was broken for certain parameter combinations newly available in 2. New project was sometimes incorrectly marked as unsaved. Retractions, deretractions and similar markers were placed at a wrong z in the gcode preview. PrusaControl was discontinued many years ago. Slic3r, Slic3rPE and PrusaSlicer extensively used admesh library for internal storage and manipulation of triangle meshes. Starting with this release, PrusaSlicer only uses admesh for loading and fixing STL files, thus the triangle meshes are only kept using the "Indexed triangle set" structure, which reduces memory consumption.
For PrusaSlicer generated 3MFs it means that the triangle meshes will be loaded exactly the same way they were stored, while earlier PrusaSlicer may have modified a mesh with non-manifold edges slightly by trying to repair it each time a 3MF was loaded. Not repairing 3MFs through admesh considerably speeds up loading of PrusaSlicer project files.
Contributors jschuh and xarbit. Multi material painting In PrusaSlicer 2. The editing tool opens with N hot key and it offers the following tools: Brush: similar to the old support or seam painting tool. Smart fill: fills a region below the mouse cursor up to a sharp edge the sharp edge threshold is adjustable at the panel. Bucket fill: replace a patch of one color with another. Notes Please note that thin features are not printable with FDM technolgy, thus for example painting a thin wall with two distinct colors will not make the thin wall printable.
There are two extra limitations arising from technical reasons: The multi material painting is limited to 16 extruders. If your printer uses more extruders, only the first 16 will be available in the painting tool. Multi material painting cannot be combined with XY size compensation.
The XY size compensation will be ignored during slicing if the object is also multi material painted. The user is informed by a notification in both cases. Bottom layers bridges PrusaSlicer is based on the pioneering work of Alessandro Ranelucci and the RepRap community on the Slic3r project. FDM supports improvements FDM supports were substantially redesigned in this release, answering frequent and rightful complaints from the users: New "snug" shape of the support columns.
By default, PrusaSlicer projects support columns into a regular grid for stability. Supports projected into a regular grid have a well defined minimum area, however they tend to leak out of regions they support along the object walls down to the print bed. We newly implement "snug" supports, which maintain the shape of the supported overhangs, thus avoiding the leaks with the trade-off of possibly lower support stability If "support on build plate only" is enabled, the support columns are newly trimmed to not land on top of an object.
However this may make the column too small to be stable Support enforcers newly take precedence over "supports on build plate only" and over "don't support bridges". This applies to both the enforcer and blocker modifier meshes and paint-on supports. Also the fact that the enforcers take precedence over blockers is indicated by sorting the enforcer meshes below the blocker modifiers at the side panel the volume lower in the list always takes precedence over a volume upper in the list Default is concentric for soluble interfaces and rectilinear for non-soluble support interfaces.
We expect this settings to be useful for printing with soluble interfaces: While the concentric pattern may produce smoother surfaces at sides of an object, rectilinear support interface may produce nicer horizontal surfaces Improved soluble support interfaces over non-soluble support base columns Printing a soluble interface directly over non-soluble sparse support is not a good idea. Soluble support material often does not stick properly to non-soluble material and the soluble material may not bridge the gaps between sparse support lines.
You can slide 3D printed part with a motor on to the longer aluminum profile. On the other side, you can fix a shorter profile as shown on the pictures.
Tighten the screws with hammer nuts. Also, don't forget to tighten an M6 screw on the side of the longer aluminum profile. Do the same on the other side. Attach middle brackets you can install as many as you want 2 or 3 with corner connectors, M5 screws and hammer nuts. We already installed Y-axis motor supports and lead screw support, right now we have to attach lead screws and Y-axis rods. Again thanks to the modularity of this machine it's up to you how long rods and lead screws will be You have to figure out good length so that it will work with the length of your aluminum profiles.
It's time to connect X axis with the Y-axis, grab the X-axis with Z-axis already installed and put it on the rods and lead screws, you will have to rotate lead screws with your fingers to push the X-axis back a little bit. I had to find something that would be good for a table of the CNC. Table with slots would be great but it is expensive. I could make it out of aluminum plate or even steel but that's hard to cut especially to cut it straight with an angle grinder.
As most of us makers I don't have a huge CNC plasma, waterjet or laser that can cut such materials but I have a jigsaw so I can make it out of plywood. I finally used table saw to cut it straight but corners should be cut with jigsaw or handsaw. Plywood is strong enough, it's easy to cut and you can easily buy it anywhere so it seems to be a perfect choice. With another 3D printed tool, I drilled holes on the edge of this plywood to attach it to an aluminum frame with M5x10mm screws and hammer nuts.
Because I don't want to destroy this plywood I added a wasteboard MDF on the top so that I can cut all the way through the material. I also added threaded inserts to the table so that I can use M5 screws to attach material to the table of CNC. You can buy something like this online, you need to drill a hole and put it in place with a hammer, simple and cheap upgrade that is really useful. Wasteboard - a piece of material that you can mill in when you mill all the way through the material and you don't want to destroy table of your CNC.
It should be replaced after some time. As the name of this project insists as a spindle I use a Dremel tool model , there are already some people that successfully use a different model like or even completely different spindles. At the end of this instructable, I also write a little bit about the different spindle that I want to use with this machine. But still, this is a super cheap entry-level solution for your first CNC with speed control and it's really good quality.
You can always upgrade it later. At the beginning of this project I wanted to add a relay to turn on and off the Dremel with a G-code command but because of some problems I would have to add a socket to plug in a Dremel and then connect that to a wall outlet and protect all of that so that it would be safe, it's not worth it and it's hard to fit all of that on such small machine I decided not to use it.
I was thinking a lot about the way of how Dremel should be attached to the spindle holder. Here is how I did it. There is a nut on the bottom of the Dremel, I thought that I can use it to fix it to the 3D printed part.
That didn't work as good as I wanted to. So I added a support structure in the middle of the Dremel with a clamp so that you can squeeze it with M3 screws and nuts.
So every time I am machining something I have to remember to turn on the Dremel, I can also easily control the RPM of the Dremel with the slider on the top of it. Don't worry that's very simple. Once you have a. Go to file examples and open an example from GRBL tab. You should see just one line of code, nothing more, that's ok. Connect Arduino to the computer and upload a program just like any normal program. If you have problems with this step try to google "how to install GRBL on Arduino" you will find tons of tutorials on how to do that and how to troubleshoot your problems.
All we have to do is send 3 simple commands:. Send those commands separately. Depends on the resolution of your stepper motors and microstepping that you used you may need to use a different value than That was a really hard part for a lot of people, it's hard to make a schematic of connection between a CNC shield and stepper motors because there is no such part as CNC shield in almost any software.
Almost any. I found a CNC shield part for fritzing! Isn't that great, fritzing is the easiest schematic software out there so anyone can understand it : I found the CNC shield right here. Before we will plug 4 stepper drivers to the CNC shield there are only three on the schematic but we need 4 , we need to connect jumpers because connectors for those are under stepper drivers. Those jumpers enable micro stepping we need to have all 3 connectors connected so that's the total of 12 jumpers but we also need 2 of them to mirror the movement of Y axis motor to the A motor and we can do so by putting two jumpers on the left side of the shield.
Now you can plug stepper drivers and then stepper motors. How to plug stepper motors? It depends on the motors that you have there is no easy answer.
I have 5 printers using hatchbox. Natural and only enough for maybe one print. The sample filament is white. Does this work with Cura 2. I can print with the older version I need 2. A shopper on Nov 21, Now I get great prints but the caveat is I have to move the component to the front left quarter of the build table in the CURA 2. Yes, works on 2. You can find a proper. I found it through reddit. Hi Gregory, I installed Cura 2. Can you share the location where I can find a profile configuration for the printer?
Reply New User U on Aug 12, Cura removed the USB capabilities in v. You must use the sd card. Will this work with a chrome Book? A shopper on Nov 25, You could conceivably get a raspberry pi and set it up to work with that, at which point you could run it from a web browser and thus the Chromebook would be fine.
Alternately, it CAN operate without a computer connection by simply loading g-code onto the included SD card, but I'm not sure the tool chain exists for the Chromebook to generate g-code. You'll need slicer software to generate gcode to put on its SD card.
I do not know of any Chrome based slicer app at this time. This may be more work than you want, but you can do it. Chromebooks have the ability to run a full distrobution of linux in a chroot with chromeOS.
The setup will take a bit depending on wifi-speed, really. Look up how to install Crouton. First download it and leave in your downloads folder on your chromebook. Enable Developer mode, setup crouton, download distro, setup distro, setup Slicer. Its a lot of initial work, but totally doable. Reply New User U on Dec 24, New User U on Dec 20, STL files of your models. This printer uses. GCODE files which you need to generate from the. STL files. The free program Slic3r works well for me but there are many other options for slicing models.
It uses. You can use models from Tinkercad. But you still have to to run the. Use Cura slicer free. Works fine. Summary: Model. Yes, it does. Does it come with software? What do you use for software?
Bruce S on Jul 26, I've successfully used a number of other slicers slic3r, Cura 2. Reply Inaccurate Josh P on Aug 2, Not really. The manual explains set up a number of third party tools to connect to it, but you will have to either learn how to model or find pre-made models yourself. No software to speak of comes with it. However there are several free downloads you can try.
I've been using Cura. There are a few free CAD programs out there to try out for design. I've only used Cura for the slicer software. The temperature can be set and its moving x,y,z ok. But it just does not print anymore.
Any ideas? Suresh R on Aug 19, You may be better off using a forum to troubleshoot, it kould be a lot of things. Also make sure the filament feed gears are turning. If you're printing from the SD card, format it and try again. A shopper on Dec 11, Each model printer has different baseline settings and users will adjust additional settings based on preferences, materials, and needs. A gcode file contains all of those settings and instructions.
You can download an STL file and load it into a converter of sorts like Cura and save it to a Gcode file that you either save to a memory card or send it to the printer via USB. Unfortunately, no. A shopper on May 26, It sits on an arm on the side of the unit. I bought a big spool and mine was roughly 12x 12 and 18 tall they are not very big. The unit itself : How do I get the app for this printer? A shopper on Oct 22, Reply Inaccurate Gagich J on Oct 22, According to my research the app is no longer available or supported by Monoprice.
The printer includes a memory card with the apps. There is not a specific app for this printer. A shopper on Dec 18, I hope this helps, and of course if you have any more questions feel free to contact us! It should. The software it uses is freely available Cura. A shopper on Dec 20, OctoPi is a Raspbian linux distribution pre-configured with OctoPrint. A definite "must have" for any 3D printer.
It does not connect via WiFi, but it does print unattended from a microSD card. Use Cura or some other slicer software on your mac, save the gcode to a microSD card, and then put that microSD card in the printer. The printer isn't WiFi enabled.
USB driver is not working with my computer running windows 8. Never got it to. So, I need about of guidance myself, and I really hope educan sees this This is where I'd start looking. Getting Cura profiles to work can be tricky. See here for where the 3D20 plugin defines which extruder to use. For reference here are the files that the 3D20 plugin installs - this may be a guide to help you figure out which files you need.
Finally - here is where the plugin tells Cura which export format to prefer. The 3D20 plugin sets the preferred output format to g3drem, and if you leave it off I believe Cura picks gcode as the default output format. Note - in order to export g3drem files you'll need the 3D20 plugin installed from the marketplace. If anyone is still interested. I started a project on github to create a settings configuration that adds Dremel 3D45 support to the newest iteration of Cura 4.
Github Link. Xpect - Awesome! I'll place a link from the 3D20 plugin to your github. If you want to release a complete plugin feel free to fork my plugin and make a 3D45 version - it shouldn't be too much work and will automate the installation of the files. If you have any questions feel free to ping me. Xpect Thanks for making this Github project for the 3D I copied the files into Cure 4.
I missed this earlier. I recommend not using that gcode from the site. Too many printers have unique settings. I highly recommend using Cura and generating a small circle or something gocde.
Export it, and then edit that file. Though personally I just grab some calibration items from thingiverse. But now, Cura has its own calibration plugin with objects you can just right-click and add to build-plate. Haven't tried it yet, but will soon. Having very recently received a 3D45 I've run into the same issues as both of you regarding the gcode that the TeachingTech's website produces.
I've found that the line reading "T0" causes the printer to go through the bed leveling calibration, heat up, then immediately quit once the printer is up to temp. With the help of previous comments I got it working with Cura 4. I get this error on startup. I will keep working on it when I have time but figured if someone solves it first perhaps they can let me know.
Would you like to reset to factory defaults? Reset will remove all your current printers and profiles. Y ou can find it in the marketplace. Thank you very much sir. Everything seems to be working and I will re slice some stuff for printing and see how it turns out however I am assuming everything will work great.
