What is the problem?
The printer starts moving the Z axis up and down randomly and the x axis the same, while extruding.
I can print the same gcode just fine, but on follow on prints it sometimes has this issue.
I've created a video of the behaviour https://photos.app.goo.gl/eucdGzQSgGDF21Gk6
What did you already try to solve it?
