Printing a few mugs with handles and I can’t seem to keep these “zits” from showing up.
They seem to originate when the extruder moves from one area to the other across an opening. It seems
to ooze out after leaving one side and deposits the “zit” on the side it returns to. The issue is more apparent in this image on the left side but both sides are equally zitty. The top section is even more pronounced between the two pyramid like structures.
I’ve got the same issue printing with PetG or PLA. In this example it was marble PLA.
I tried reducing the retraction and reducing the temp down to 195. This changes made no difference.
Printer is a Taz6 Lulzbot.
0.5 mm nozzle.
I am using the CURA LE version by Lulzbot
0.2 mm layer height
wall thickness 1.0 mm
wall line count 2
Printing temp 205 C
Build plate temp 60 C
Print speed 50 mm/s
Retraction distance 8 mm
Retraction speed 15 mm/s
z hop when retracted disabled
regular fan speed 80%
Would enabling the z hop help with this issue?
