How to print from TPE / FLEX (it fails at start)
Hello,
Today I was trying to print simple part using MK4 with 0.8 mm nozzle and TPE 32 from filament PM. The print failed at very beginning during the nozzle cleaning, or calibrating or whatever the printer does just before the printing. Sometimes collision was detected, sometimes it failed with error message about failed nozzle cleaning.
After several failed attempts, I switched TPE for ABS filament, initiated printing again but with different part, and it printed with no issues.
I use settings for TPE 88 instead of actual TPE 32 because there is no profile in Prusa Slicer for TPE 32, only for TPE 88. Could that be the issue?
Also the TPE 32 filament was sitting sealed unopened in my garage for about 4 years. Not sure if that is the problem.
What is the problem?
