Hi, I'm new in the 3D printing community and maybe my questions or problems are stupids. I recently Got an Ultimaker 3 at work and I have some difficulties to make it work correctly. When I launche the print of a small part in black PLA and PVA support from ultimaker using cura fine profile. There's no problem but when I multiply the pices on the pannel to print 20 parts as once. My black PLa seems to got stuck. After 5-10 layers, the black pla stop printing but the feeder continue to pull. It makes the boden tube jump form motor. See Pics ? Is there any settings to look away for this ? I've already removed the filament, cut the flatened part and retry a lot of time but this problem seems to only occure when I print large parts. I putted the g code of a parts who works and the g code of a plenty of parts on the same pannel who don't works. I have already read the following articles : https://ultimaker.com/en/resources/36108-how-to-fix-feeder-issues https://ultimaker.com/en/resources/36109-the-feeder-is-ticking-back-skipping Sorry for my bad english it's not my first language.
