Hi cjh,

you should follow these instructions to get an answer. Very important!

Basic Information:

Printer Model:
MCU / Printerboard:
klippy.log

Fill out above information and in all cases attach your klippy.log file. Pasting your printer.cfg is not needed
Be sure to check our Knowledge Base and in particular this and this post

Describe your issue:

…

It would help to translate your comments (I’m just guessing, Chinese comments) in your printer.cfg to English. I guess, most guys here don’t speak Chinese.

I don’t really get the problem you described in your OP.

Good luck, hcet14
