Thanks, I done manual levelling, but tried the active levelling and the printer turns off and restart. Any suggestions of what could cause this? I’ve added new cores and calibrate them everytime.The material has delivered other good prints before

Do you have a gcode template of a part to troubleshoot issues? By the way, this is an ultimaker 3 not the S3, just to clarify 🙂 Helicopter_Front.gcode

I thought that also, I checked it 4 times. But I noticed also that the skirt layer on the left is thinner than the right one, even though I have levelled the plate multiple times with a card.

Hi Marimakes, I have a ULTIMAKER s3, AA nozzle with black ULTIMAKER 3 PLA and BB with PVA. I have printed a few times with unsuccessful results and mostly the file was irrelevant. the latest was this one from thingiverse: https://www.thingiverse.com/thing:1885007 I tried to print with one printcore only, which obviously is not allowed, than I removed the pva material and send a file to print. The same ridges appear and they seem to be all related to the BB core scratching on the PLA material of the build, causing imperfections or material drag in the worse case.

I'm going to revive this site, I have had multiple of these blobs and changed the print cores, I didn't know what cause the failure, I have: - changed printcores, - re-design and installed belt clips with tensioners, (thinking axles fell due to gravity) - Re-calibrated XY axis, manual buildplate, Level switch, etc. - Lubricated every axis according to manufacturers website. I have done the above so many times, I go through the menus with my eyes closed. I've used different methods to secure the prints (salt method, Glue stick) but in a recent print, I've noticed a bang noise during one of the prints, When I checked, the printcore should have changed from the PVA to the PLA and it didn't, the noise was from the printer hitting the dry PLA. I am at whit's end with this printer, so I am requesting some wise suggestions from this community
