    Ultimaker 2
  1. I really appreciate your responses, but I'm still not getting this too work. first I reset the unit to factory resets - still backwards second I redownloaded and reloaded U2 firmware - still backwards third As a test I downloaded U2+ to see if that reverses the extruder - still backwards Fourth I tried the marlin alternative firmware - still backwards Fifth.....I don't know. I'm getting the firmware from github....I assume that is the right location. Any ideas are appreciated
  2. I've got two problems, but I want to solve the first before attacking the second. My extruder is running backwards.
  3. I am a average user with good skills. Ultmaker 2 has been running without major issues for 6 months after I purchased used Yesterday, I went to re-print an object that I had already printed......so this Gcode worked! The unit will not heat up If I go to settings, I can manually heat up tip and bed but when I start a print....nothing So I tried updating firmware and that appears to have worked....but still not getting any heat.
