  1. Tried out the Import SolidWorks files as STL. A new plugin that enables SolidWorks compatible .SLDPRT files to be imported directly into Cura, where they are automatically converted to .STL format. This plugin can be found in the plugin browser. Every SW part I brought in failed to load regardless of the "fine" or "course" setting. That said, it's a fantastic idea. How can I help with the further development of this plugin? SolidWorks 2017 x64 Edition SP3.0 running on Win10 64 bit.
  2. Well it seems everyone has missed my point. I'm well aware of the ability to make a solution of PVA from left overs. I just thought it's "interesting that it's used as a release agent in that industry, but we use it as a means of improving build plate adhesion". Just idle musing on my part . . .
  3. According to the specification sheet: XYZ accuracy 12.5, 12.5, 2.5 micron UM3 Specs
  4. I did not know that PVA could be purchased in bulk liquid form and is used in the fiberglass industry for a mold release agent Can be sprayed on with and aerosol spray system. Check out this web site: PVA Video Interesting that it's used as a release agent in that industry, but we use it as a means of improving build plate adhesion.
  5. Glad the Outer Wall Wipe Distance helped. Probably don't need the Draft Shield any more. Did you reduce the Print Jerk and Travel Jerk? You might also want to experiment with the "Z Hop" settings under the Travel Menu. Solomon Islands huh? Sounds exotic. Maybe even idyllic?
  6. That is the Z scar at layer change. Try adjusting the "Outer Wall Wipe Distance" to 0 Set "Print Jerk" and "Travel Jerk" to 12 and 15 respectively. Play with the "Coasting" under the Experimental Menu. Never did much for me, but worth a try. I have found that Cura 2.X.X has never done as smooth a job on the Z scar as the 15.X.X versions did. However, I was using a UM2 Ext with the 15.X.X versions and a UM3 Ext with the 2.X.X versions. So your results may vary . . .
  7. I agree, but I did point it out only because the original post mentioned the bottom as well. And, I agree that it would be nice to have a top layer feature too. I guess nobody else thinks this is a good idea . . .:(
  8. Glad we were able to help. Visit the forum often. There is a wealth of information here.
  9. You might also want to investigate the settings used to generate the exported STL file. I do not know what application you are using for the initial design of your parts, but in SolidWorks the export to STL dialog contains a number of setting the control the triangles used to represent the 3D surface of the model. Here are the settings I use from SW. Your model appears to have cylindrical surfaces made up of too few facets. Decreasing the angle of the STL model will smooth out the facets, but will make the file size larger. No need to apologize for your English. Most of us English speaking folks are lazy and never even bother to try to learn a second language:) Hope this helps . . .
  10. Thanks XYZ. I tried setting all of my settings back to default and it cuts perfectly. What I found was causing it, was changing the layer height to 0.2 or below, with a first layer height of 0.3. I then found if I changed both the layer height to 0.2 and the first layer height to 0.2, again it cut as expected. Modifying Support Horizontal Expansion all the way to zero (default is 0.2) makes no difference to the result. I'm using it on a Wanhao Duplicator i3 Plus, with a 0.4mm nozzle. I might try running it on a Windows box to see the results. Using a single extruder machine for both the object and the support often yields vastly different results than dual extrusion machines using the same settings. That's why it is so important to include as many details as possible when posting / describing a problem for help. Glad you were successful at finding a solution.
  11. Thanks for the suggestion. My default setting in 2.6.2 was 0.2mm. Reducing that to 0 made no difference. Increasing it to 1mm made a noticeable change. Even a value of -0.4 has no difference on the results. Anything above that just removes all support. Here's a screen shot of Cura 2.6.2 of your file from my computer. Win10 Pro, 64 Bit. My machine is UM3 Ext using PVA for support from Extruder #2. All of the default "Normal" profile settings were used except for changing Build Plate Adhesion Type from Brim to Skirt and setting Horizontal Support Expansion from default of 3mm to .5mm What printer are you using? Perhaps a Linux problem? Hope this helps . . .
  12. Try reducing "Horizontal Support Expansion" setting from the default of 3 to something smaller. See this post for more information. https://ultimaker.com/en/community/50158-why-so-much-support-on-900-angles-in-261?page=1&sort=#reply-183942
  13. I posted a similar request / enhancement back on July 3, but I've had no responses from anyone on the forum: I would like to see the option in Cura to allow for a different Top / Bottom Pattern in the same print. We already have the ability to choose a Bottom Pattern Initial Layer. Why not be able to choose a different Top Pattern and Bottom Pattern for the entire model? For instance, Concentric for bottom layers and Lines for top layers. Seems like it should be fairly easy to implement. Thoughts?? Maybe someone will pick up on your thread?
  14. As far as I can tell this app stopped working with firmware 3.6. Has it been abandoned?
  15. SandervG, I think you may have mis-understood the request. I believe Berninni55 is looking for a model of a shoe last so he can print one. A shoe last is the armature around which a shoe is made. Shoe Last

  17. Robert, Thanks for the tip. Your suggestion to reduce the "Support horizontal expansion" setting has solved a problem for me that has prevented me from using any Cura version after 2.4 because of all of the extra support that was in places that were completely unnecessary. Before and after images when setting this from 3 (default) to 1. Also, as you can imagine, reduced the print time from 3 hours to 2 hours Never had this problem with Cura 2.4. Hence I have used 2.4 exclusively for production work since it's release. Now it would appear I'll be able to move on to 2.6.1 and enjoy all of the benefits of the ongoing development of this invaluable tool. There are so many hidden settings in Cura these days without clear explanations as to functionality. Thank heavens for this forum !!! Thanks again for your valuable tip . . .
  18. Please keep the forum posted on this as others have experience this problem . . .
  19. Have you tried reserving your printers IP address in your router? I had this problem with my UM3 Ext machines, but after reserving their IP addresses never had a problem since. Perhaps this will work for you as well?
  20. There was some discussion here on the forum about zooming in based on the cursor position before 2.4 was released. That's a really usable feature. The double click functionality you describe is a feature in SolidWorks, although I never use it since pressing the "F" key accomplishes the same thing. Cura 2.6 Beta still does not have either of these. Perhaps in 2.7??
  21. Here are the instructions I received from GR5 (the Minion on this site) for changing the nozzle on the 3DSolex core: The Olsson block torque wrench (7mm socket) works great except for one critical detail. You have to hold the hardcore block in place while removing and inserting nozzles. This means you have to remove the core from the machine while you do this. To avoid having to reboot the UM3 only remove the core while it is cooler than 50C. Rebooting the UM3 isn't a big deal though if you forget and remove it while hot - it just takes - what - 2 minutes? There is a very thin steel neck above the heater block and below the aluminum fins. It is about as thin as aluminum foil. If you use the Olsson block wrench to remove a nozzle it will snap the neck. That's why you will get a wrench to hold the heater block still. In any case, the GR5 Store can repair it if you should break it. https://thegr5store.com/store/index.php/ Hope this helps . . .
  22. Have you tried this: Disconnecting the Printhead (UM3/UM3X) https://fbrc8.zendesk.com/hc/en-us/articles/115000062743-Disconnecting-the-Printhead-UM3-UM3X- Hope this is the solution for you . . .
  23. I have not resolved this problem yet, nor have I had the time to experiment in the last week (I have been printing almost non-stop). Yes, I only print with PLA. It did this out of the box, and still did this after I did a firmware 'upgrade' (pretty sure that Cura just flashed the version that was already on the printer, since the version info in the printer didn't change). Seems you have answered some of these questions multiple times !! All I can add is the same question I've asked all along. Have you tried Cura 2.4? Cura 2.5 is the first version that is multi threaded, and I personally have found that it does do some odd things. As a result, I am still using 2.4 for my production work. That said, 2.6 Beta is looking very promising . . .
  24. Was this problem ever resolved? Were you able to test the same file using Ver 2.4?
