@rescuer135 Sounds a bit like https://forum.creality.com/topic/2271/the-ender-5-pro-home-position?_=1625043159923 where using a new micro SD card solved it in that case. Maybe somebody can explain why.

Dear @ACrealityMan Format the memory card first, then re-copy the gcode file to test Replace the memory card with a new one (less than 16G) gcode file name should not exceed 16 characters; no special symbols Stick a little alcohol on the SD card and repeatedly unplug it.

@Jvelez75 I am having the same problem

@pro_info FYI this is still a problem. I noticed that the Simplify3D profile in the SD card gcode files has G29 in it's starting script, but the actual GCode doesn't have it. My extruder kept crashing as well once I took the G29 out all works fine.
