Basic Information:

Printer Model: sovol sv03
MCU / Printerboard: SKR Mini E3 v3.0
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

Pin PF0 is reserved for crystal. I just copied and compared three existing printer.cfg files and they all use:
[stepper_x]
step_pin: PF0

not sure what the issue is…x axis is plugged into what I assume is correct if X motor pins go to XM…

Welcome. I have no clue what your problem might be! Please have a look here I need to hire a professional to work on persistant MCU errors - #3 by hcet14 how to start a new topic.

Good luck, hcet14

Sorry - what is so misunderstanding with that post?

Oh gosh, thank you for clarifying this. I don’t know why I didn’t think that the printer configs I’ve found online were using the stock creality v2.2 board, which uses step_pin PF0.

Looks like I’ll have to be making a lot of pin adjustments.
