What is the problem?
When printing with octoprint, seemly randomly it raises Z to full height and goes to far corner and just extrudes.
What did you already try to solve it?
My apologizes but I do not know how to attempt to solve this. The problem never happens when printing directly from sd card. This issue has happened three times. I have been able to print about a dozen prints without issue using octoprint.
