  1. I am also wondering if it is abrasive? Does it need hardened nozzle & feeder?
  2. You don’t create designs in Cura. All of the critical dimensions (nozzle size, layer heights, etc.) are in mm across the 3D printing community. where other units matter is in design software, like Fusion 360, Freecad, or TinkerCad, to name a few. Those design systems allow you to design in whatever units are best for you (though if you design in inches and enter a dimension as 15/64”, it will show as the decimal equivalent 0.234375”. In that same software simply set the STL export units to mm (STL files are dimensionless). And, BTW, I am also in
  3. In my quick searching I found the Ultimate 2 is a Weedo F150S, but I did not find info on nozzle type.
  4. Your printer is also known as the Malyan m200 v2. here is info on the nozzles: https://www.mpselectmini.com/parts/nozzle
  5. There are several Monoprice printers, made by different companies (Monoprice rebadges the printers). So before we can answer, we need to know the full model name.
  6. If you think about the three point leveling, the back screw is only going to adjust the owner all angle front-to-back. if the back left corner is too high, that means the front right corner may be too low, causing the bed to pivot around the axis from the front left screw to the back center screw. Another thing that could be happening is your gantry rods may not be parallel with the bed, and if the angle changes front to back, due to rods not firmly attached to the belts for example, that could make leveling nearly impossible. Check for any play in any of th
  7. Search for Cura on GitHub. That’s where bug reports are best submitted (in the issues tab)
  8. I haven’t used that brand, but I’ve found with Ultimaker Nylon that I have to use glue and a brim for long pieces.
  9. The typical slicing strategy is to alternate directions so the layers cross at 90 degree angles on alternating layers. Only the wall lines print atop each other, and trying to offset those would cause a rough outer surface.
  10. I don’t think you have layer shift happening. I think you have a bit of underextrusion and are printing too fast, especially with a .3mm layer thickness. That fluctuation in part outline corresponding with changes in layer geometry suggests you are at the limits of the rate the material can be melted and pushed out. i would try it at 50-75% speed and 0.15mm layer height. That will likely make it less likely to break.
  11. I think it is in cases where one or more edges of your model print on top of the edge of support. For example, an overhang, or a long bridge. Support is meant to bond weakly to the primary material, so if you try to print right at the edge it can sometimes cause problems. in your case above, most of the support was surrounded by walls.
  12. You need to turn off supports. That’s what the light blue indicates. As for pausing, I’ve done the same thing but for some reason it only works when specifying the height by layer number.
  13. That axle is just an idler, so moving the gear one tooth on the belt shouldn’t be a problem. The curious thing is that you didn’t have this problem last time you set it. Is the matching gear on the other end of the rod also foo in the same manner?
  14. You could try running the STL file through http://service.netfabb.com It’s a free service that just requires registration.
  15. Here’s the link for the personal use license. https://www.autodesk.com/campaigns/fusion-360-for-hobbyists
  16. The last version of Cura in the same generation as the version you got from ANet is 15.04.06. I’ll link to another post at the end that has a link to it. I can understand your reluctance to upgrade stuff that is working for you, but considering you just installed Cura, you might want to give the later version a try. After the 15.X generation, they started with new versioning that began with 2.X and is now at 4.3 with 4.4 in beta. As for your “no top” issue, I don’t see that. The red lines indicate “shell” and only apply to the horizontal edges. The top surface is always
  17. @mrtinfy Yes. There is an issue...but it is not as simple as you think. Many of us run Cura on systems that have the newer redistributables with no problem. My Surface Book v2 runs it fine in its laptop configuration that uses the NVidia GPU in the keyboard. But it will not launch properly when in tablet mode where it uses the integrated Intel GPU. I have given this info to the team both here in the forums and on the Github issues section, but I don’t pester the team asking, “Is it done yet?” One of the truly frustrating things in software development is to have bugs that a s
  18. It makes perfect sense if you are a support person when a non-programmer user of software not written by Microsoft is asking Microsoft to fix an issue. I’m sure @mrtinfy means well, but he needs to stop trying to wield that comment like a cudgel. He also needs to understand that in many open source projects, there are many packages that are used, but not written or supported by the developers of the product. If Package “X, version 1.23” is being used by the project, and that version has a hard dependency on msvc redistributables 2015, that could make the project as a whole not work wi
  19. The upward-sloping spikes are antennas. Caused by oozing.
  20. In this kind of situation where the support is fully inside the external walls, the horizontal expansion serves no purpose and puts thin walls of support on the outside. These thin pieces almost invariably break off and contaminate the PLA portions.
  21. Sometimes all of the selection handles are a little finicky. what I found works for me ( whether using the rotations, linear moves, or sizing) is to move the mouse until you see the hoop (line, whatever) glow a brighter color. Then click and drag.
  22. Reduce “support horizontal expansion” to zero.
  23. I gave you what I believe to be the algorithm. Let me state it a different way, and also answer your question about line colors. the yellow wall lines are the “inner” walls. The red are the skin, “outer“ walls. It prints all of the inner walls first. Then it prints all the outer walls. The Outer before Inner simply swaps the order of these operations.
