Topic: screws loosening
I have had to retighten several screws on the extruder assembly lately.The two long screws under the stepper motor seem to back out and the whole assembly get loose.Even after tightening there is a lot of play. I did replace the jigsaw with the mk4.
Is that tie wrap around the motor still necessary?
