kisslicer - Ormerod help (no replies)

Hi,

I just installed kisslicer and try to print a Ormerod spare part. I found that there's no skirt printed, and the extruder'gear spin back and forth, but not extruding anything . it shows :

Error: invalid M Code: M542
[ERROR] Error: invalid M Code: M542


file: M551 P32000 S900
file: M543
Error: invalid M Code: M543
[ERROR] Error: invalid M Code: M543


Ormerod can't process part of code that kisslicer created ???
anyone who familiar with kisslicer please help.
