@Mr.Exocomp Have a look at the machine code (startcode) for the printer and copy the machine start code into an editor. You will find somewhere this entry
;===== for Textured PEI Plate , lower the nozzle as the nozzle was touching topmost of the texture when homing ==
;curr_bed_type={curr_bed_type}
{if curr_bed_type==“Textured PEI Plate”}
G29.1 Z-0.04 ; for Textured PEI Plate
{endif}
This is where the Z Offset is set to be lowered by 0.04 mm
You can amend this to
;===== for Textured PEI Plate, High Temp Plate and Wham Bam Plate ===============
;curr_bed_type={curr_bed_type}
{if curr_bed_type==“Textured PEI Plate”}
G29.1 Z-0.04 ;squish of -0.02mm for Textured PEI Plate
{elsif curr_bed_type==“High Temp Plate”}
G29.1 Z0.03 ;raise of 0.03mm for High Temp or Wham Bam Plate
{endif}
i e depending on which plate you chose, the offset will go up or down.
You can amend Z0.03 to more or less
positive number = offset up
negative = offset down (more squish)
I use this for my X1C)
