  1. Before I upgraded my stepper drivers on my UMO, I added some rubber feet made from automotive heater hose. It was what I has on hand and it made the printer much quieter. A difference in print quality was not noticed. I printed some simple cylinders with a through hole for mounting. The OD is a slight press fit for 1 inch hose. Screwed them to the bottom. Pushed on 4 pieces of hose somewhat longer than the spacers.
  2. I tried to register. Still no pin in the map. Have any of the participants been contacted for assistance?
  3. I filled out the form, but see nothing added to the map. Is this because I am an individual, or a glitch in the form automation? I have 2 Ultimakers that can be available. One is dedicated to ABS, the other flexible for many types. I have ample stock in ABS ans PLA on hand.
  4. There are actually quite a few ways to create an stl from a topo map. This site works ok, but the cropping and manipulation of the map pre download is awkward and kind of imprecise in my opinion. No control over the aspect ratio. http://jthatch.com/Terrain2STL/ This site works good. I think it's been tweaked for the good since my last attempt. https://touchterrain.geol.iastate.edu/ I am importing the gray scales into Cura 4.3.0 and using the import utility to generate the STL. I am not sure where I got the map I am currently using. Maybe from Google. The map
  5. I figured it out. Select the model you want to use as a subtract solid. Set the "modify settings for overlapping models" for this solid. Then pick "select settings". You can then set whatever slice settings you want for this piece. If you set wall thickness, top/bottom and infill to 0, the piece will be regarded as a subtract from the other models.
  6. Thanks for your thoughts Geert. I have created empty voids by subtraction in CAD, but never by placing an STL inside another. What I'm referring to is actually very similar to the support blocker function. Although I don't know if the support blockers are made up of STL files.. Those can be partially interfering a support and/or the printed model. Any portion that interferes the model is ignored, but the interfered support is effectively cut away. I can tell you that I've done the practice in question in the past few months. I just don't remember the exact steps.
  7. I did this once before. There is a way to "modify settings for overlap with other models" and/or "modify settings for infill of other models" (in per model settings) that results in one of the models (overlapping the other) having basically 0 wall, 0 infill and 0 skin, and effectively performing a boolean subtract within the slicer. Can someone remind me of the specifics of this method? Thanks
  8. Is there a change log for the new version?
  9. I see that the part wall there is actually triangular when viewed top down sectioned through that area. If I change my normal .8mm wall size to.6, the surface is filled in. If it doesn't affect function, I'd prefer to keep the thicker wall. I am printing this in ABS on my UMO. The only nozzle available for my UMO currently is a .9mm. Not sure how well that would print at .6mm.
  10. I am seeing an anomaly in the way Cura is slicing the clamping dock. Will this open hole in the planar face of the cone feature have any effect on docking function? Thanks
  11. Nice work Snowball. Tell us which scanner and software you used to achieve these great results.
  12. I finally picked up a second hand UM2+E to add Mark2. I have a few questions as I get started. Does anyone have any good or bad experience with using Makergeeks Raptor PLA for the printed pieces? I happen to have a roll of it. Same question goes for ABS. Thanks
