  1. I've noticed the inverse problem on my printer. If autoleveling is not set to always, It tries to print at or below glass plate level, so it never extrudes and just scrapes on the glass. Manual leveling doesnt fix the problem either. Putting it back to always makes it work properly.
  2. Did you try contacting fbrc8.com? They are U.S. based part supplier. If they dont have it or can't get it, no one can. They ship super fast. Last ditch effort would be to try McMaster-Carr, Fastenal, or Grainger. Can determine the thread size with a thread checker or calipers, and then measure the shoulder length, thread length, etc to get the exact screw you need.
  3. Ok Ultimaker Community. It appears I may have found a bug with UM3 5.2.8 firmware! If turn active leveling frequency less than "always", the machine appears to fail to remember the offsets, and print at the wrong z height. The moment I turn active leveling frequency back to always, it prints at the proper z offset from the glass plate. Not on "always", the printer prints at the absolute 0 Z cordinate as the glass plate, therefore it can never extrude. Can anyone else replicate this?
  4. Ok, so scratch that. Both cores are scraping the glass and not printing. What the heck. I dont understand.
  5. Hi all, I am having a problem with my UM3. Today I replaced my short belts and the short bearing the print head. After reassembly, I loaded my AA 0.4 print core into slot 1, and BB 0.4 print core into slot 2. After printing a simple cube using PLA test from core AA, I went to print something that used the BB core with PVA. After doing the prime blob, the BB print core began to "print", but it appeared to only be scraping off the glue stick off of the glass. When the bed retracts, some PVA extrudes out. I have ran active leveling, and finally manual leveling and each time I keep getting the same result for my PVA adhesion layer. I have ran diagnostics on my level sensor, and UM3 is saying it is functioning ok. I have also tried to clear the print head using PLA filament and the cleaning routine. Any one have any ideas why this is happening? What could be causing this?
  6. Hi all, I am looking to purchase a used Ultimaker 3 or 3 Extended located in the U.S. Preferably in Los Angeles or California, but I'll take what I can get. Only request is that machine works well and has no issues. I'm an artist and creative director and its time to finally invest in my own machine. If anyone has one for sale in the U.S. please let me know. Cheers, Jonathan www.polygonfuture.com mail@polygonfuture.com
