Tried using KOMB for nozzle cleaning I have settled with the following:
brush_size_x is actually 40mm and variable_brush_size_y is 10mm but either value returns bound error, i.e > 301
I have also tried Nozzle_scrub.cfg but I get bound errors there too...
Do I need to tweak position_endstop: 300, and position_max: 300 in printer.cfg?
Note, I'm using virtual endstops...
Code:
variable_brush_location_x: 235
variable_brush_location_y: 290
variable_brush_location_z: 1
variable_brush_size_x: 30
variable_brush_size_y: 6
variable_brush_size_z: 5
variable_z_hop_height: 5brush_size_x is actually 40mm and variable_brush_size_y is 10mm but either value returns bound error, i.e > 301
