  1. I forgot to add it was all modeled in Sketchup and sliced with Cura
  2. I have had my UM2 for a year now and can say without a doubt I love my machine. Once I got past the initial teething and upgraded the problem areas she prints beautifully. I am a C-5 quadriplegic with no finger function and I have no problems running and maintaining my machine on my own "for the most part". Oiling, leveling, changing filament, cold pulls, changing tips, (O-BLOCK), removing prints, cleaning the bed, support removal. This is a HUGE deal for me as it allows me to be creative and build adaptive equipment that brings me more independence. I love and want to thank the UM commu

    New print

    Version 1.0


    New print
  4. I also use colorfab from printed solid for PLA prints and have had no issues with quality as it simply prints beautiful. I avoided ABS for my first year of printing because of stories about adhesion issues and being new to 3d printing I didn't want to add extra issues. Now that I understand my machine inside and out I have started printing with IC3D ABS and it prints just as good as my colorfab PLA/pha. I use the Olsenblock with the .6mm tip, 235c, .2 layers, 45mm/s, bed 105c, 12 lines of brim, fans 15% for overhangs past 30 degrees, and for bed adhesion I use got to be ultra glued invisibl
  5. I use a small set of files I got from harbor freight along with a nice kobalt knife set from Lowes and they work great on PLA. http://www.harborfreight.com/12-piece-precision-needle-file-set-4614.html http://www.lowes.com/pd_525794-23002-KS20_0__?productId=50223299&Ntt=kobalt+knife&pl=1&currentURL=%3FNtt%3Dkobalt%2Bknife&facetInfo
  6. You can try glue stick, hair spray, blue tape or extra strong hair gel. I use got to be glued mega hold clear hair gel and it works great. I have a clean sponge I moisten with 90% alcohol and add a small amount of hair gel and apply to the bed while it heats up. I apply it like waxing a car in small circular motions and find the gel lasts for several prints. Also keep in mind that a .8 tip flows 4x the material a .4 tip will at the same height and speed, so you may need to print hotter to get better adhesion. I hope this helps. Also in the future include what brand filament, bed, and p
  7. I love the setup you have created and was wondering if you could fill us in on your print settings for such a large print? What brand of filament did you use to print the elephant and how much filament was required to print that behemoth? Also what size nozzle, layer resolution, print temp, and speed? This information will help backers get off to a good start in the large scale 3d printing realm and help reduce time and filament waste. Thanks
  8. I like protoparadigm pla however they are going through changes and have been out of stock of all 3mm filament for months now. While waiting I ordered 4 spools of colorfab pla and look forward to see how it prints but the price is quite high imo and their spools hold 25% less then protoparidigm plus they charge shipping where proto-p is free. I really hope the market gets more vendors of quality 3mm filament so the prices drop even more but I don't see that happening any time soon in the US. Colorfab through printed solid $39.00 for 750g plus shipping 5.2 cents per gram. Came in a pl
  9. I seccond this... The x and y rods should be well oiled and kept clean. The printer uses brass sleves not bearings on these rods with very little clearence. If you fail to keep them clean they can become sticky and in some cases freeze on the shaft. I use liquid bearings a synthetic oil that works great. I like that it doesn't become tacky and the bottle comes with needle tips for easy application. Your rods look like they have never been touched. That or you print in a really dusty environment, either way matinence is needed there. I would also try printing slower as your machine h
  10. And here is the problem with text format as in no way was I trying to be a smartass but being thats what you got from it. I'll keep my mouth shut from here on out to prevent any further confusion. I said it's funny because an idea from anywhere can become a possible solution to a given problem no matter the backround.
  11. In time I hope to see great things from a solid dual head setup
  12. Next time add fiberglass fibers to the mix and it will be far stronger and even if you crack it the fibers will hold it together
  13. There is a plugin for sketchup that allows you to export files as STL's got to sketchucation.com. Also cura supports DAE files. I use sketchup for all my prints so far with no issues. Just make sure the model is solid.
  14. Being a quadriplegic, having no finger function limmits my life beyond measure. To combat my lack of physical ability I am constantly designing things to make my life more accessible. Here is my RC lawnmower I designed and built with my friends so I can cut my grass. Now with my UM2 my ability to be creative has taken off and will lead to many more adaptations. I will post a video of my custom 3d printed PS3 controller for quadriplegics soon. I hope you like it.
  15. I can't wait to see what new things come from the UM team tomorrow. I had a great showing at the Orlando maker fair with my UM2 printed accessible play station controllers for quadriplegics this past weekend. I had the only UM2 there but it stood out like a gem and was a crowd magnet.
  16. I came across this new kickstarter project and thought I'd let others know. Taulman is offering 6 new filaments that look promising.
  17. Did you get a chance to print my test cube? I'm curious about your results being you liked my post but no reply yet.
  18. I couldn't get any good pictures with my gopro they all were blurry to the point you couldn't see the gap between infill but here is the 20x20x4 that printed fine https://www.dropbox.com/s/05jfh5clzyixt76/20mm-cube.gcode?dl=0
  19. I will post the code after work tonight and take a few pictures. The quality of the pictures wont be great as it is hard for me to take good pictures with my non working hands but Ill give it a shot.
  20. ok i printed your gcode and got the same results as you with gaps between infill on the top. So I made a 20x20x6mm cube in sketchup and ran it through cura 14.7. printed at .8 walls, .15mm ,230c, 45mms, 20% infill , silver protoparadigm PLA. and it came out perfect. UM2
  21. I will try printing your gcode file tonight after work and see how it goes. I don't know if it will help but have you tried a complete uninstall of cura then download and reinstalled the current version from the website? I saw you reverted back to 14.1 at one point but try a full clear n reinstall with new files. I figure it is worth a try as it only takes a few minutes. If you do Ebay that printer please give the bidders a heads up about the issues it has.
  22. T-glase is FDA tested to be food safe and prints well http://taulman3d.com/t-glase-features.html
  23. I love sketchup and enjoy the free plugins that are avaliable. I use solid solver, solid inspector, remove inner faces, and round corner, along with a few others I can't think of at the moment. One thing about round corner I find anoying is once you use it you can not use push/pull on the surface any more. So I create my design, make a copy, and round the corners last. This way I can make adjustments in the future. I research and download my plugins through Sketchucation a wonderful site for anyone using sketchup. It has loads of great information. http://sketchucation.com/
  24. For those who want a dual extruder printer and don't want to wait for the UM version there is a G-Max kit out that has a 16 x 16 build platform with a dual extruder add on. The only down side is it does not have a heated bed and requires you to assemble it. But it looks like a nice kit for the price. I have been following this printer for some time and believe for my next printer I will give this a try if the UM version is not ready by then but first I want to buy a cnc router. http://gcreate.com/gmax-printer/
  25. The problem with a peltier is when you apply power one side gets very cold however the other side gets very hot and needs its own cooling to maintain the tempiture difference or the element will burn out. I played with a few trying to make a self contained recirculating cooling vest but the elements were not very efficient and required large heat sinks. But it doesn't hurt to explore any and all possible options so good looking out!
