Problem with material change
I try to print with PET at 215 deg C and BVOH. PET for first layers is loaded without problems. When the material has to be changed the nozzle stops at the wipe tower and the PET is retracted. Then the BVOH is feeded and pulled back and feeded again. Then a rattling noise comes from the extruder for while until the print head moves to a parking position. On the wipe tower a blob of material is left.
Seems that the feeding isn't stopped in time but this don't happen with PET or PLA.
