Random shift on Kobra 3 Max
This started the other day and is driving me crazy. When printing, all of all sudden the print head shifts anywhere from 1-6 inches to the right. It will do it anywhere from layer 40 to 80. I did a test print with a small cylinder and a vertical wall, both printed fine. In the attached picture the cylinder on the left printed fine but the two objects on the right both shifted about an inch. The print head is not hitting anything that I can find, I can move it around and nothing is even close. When I stop the print, the print head moves all the way to the right and slams into the cutter activator and still tries to keep going so it seems like the printhead isn't even aware of what it is. Belts seem fine as far as tension goes and I think loose belts would be more of a gradual or continuous shift. It is happening with both PETG and PLA. I did reprint something I printed over the weekend and it printed fine.
I have tried to be out there to watch it but have not been able to capture it happening.
What could be going on to cause this?
