Dear community, Ihave a UM2+, I'm trying to print some masks for COVID-19 and I don't know why, after a 30 minutes (more or less) the printer stops. If I tried to restart, the nozzle goes down crashing to the part. I have to abort the job. Since yesterday I have this problem (Sorry my english in spanish is better). I need help, I have to produce 200 pieces for my company!!!
