Good day to everyone.
I am using an Ultimaker 3 extended printer and I have some problems with the PVA filament, after 1 day or 20 hours of work the extruder stops printing and does not print with the PVA material and the printing becomes a disaster (due to the absence of supports).
In the part of the feeder the material is worn out by the effect of the motor, someone who can help me and tell me what the reason for the extruder is clogged.
I have been cleaning the extruder twice, between extrusion periods of about 33 Hrs
Note: I am using the temperatures that handle the filament and the CURA software.
