I have Ender 3 with Klipper.
In my config:
[stepper_y]
step_pin: PB10
dir_pin: !PB2
enable_pin: !PB11
microsteps: 16
rotation_distance: 40
endstop_pin: ^PC1
position_min: -30
position_endstop: -30
position_max: 200
homing_speed: 50
With this, when I issue G1 X0 Y0 the printhead is actually at 0,0 above left bottom corner.
But then it may not move farther than 200 mm on Y axis. How do I retrieve those 20 mm? How do I set an Y offset?
Not that I print that much, but it doesn't work with the print bed calibration model. So it tries to travel to Y209 and fails.
