Odd XYZ Calibration Issue
Hello,
I got my mks+ kit a few weeks ago. Immediately after assembly it passed all calibrations and I was able to print a few test objects. It wasn't perfect, and I had the printer on my desk (which was a little shaky) so I moved it to a new surface but wasn't able to use it for a week due to being busy.
Since turning it back on, it can pass self text and z-axis, but the xyz calibration refuses to work. The calibration runs through finding all four points but at the end simply states 'calibration failed. check handbook'. Any suggestions?
I have tried adjusting the PINDA (using ziptie method, as well as a little below that for good measure) and redownloading firmware with factory reset, which are the two most common suggestions I saw for this issue. The PINDA is also turning off its light correctly when near metal.
Any suggestions? I am a bit lost and frustrated that I have stepped backwards.
Best Answer by Robin:
Check the grub screws on the x and y motor shaft pulleys. They are the most common cause for layer shifts and they can screw up the calibration because shifting on one or both axis makes finding the calibration point impossible.
One needs to be exactly on the flat part of the shaft.

If at first you don't succeed, skydiving is not for you.

Thank you for the advice! Both the x and the y pulleys were slightly off. Calibration passed.
