Issues homing homes x and y separately, but not when I click home all
When I select home all, x homes as normal, but then Y will act as if it's already homed and move forward 150mm. Though when homeing each axis individually, this works as expected. I'm using sensorless homing on the octopus board with tmc 2209 drivers. Current Homing override code is below
[homing_override]
set_position_z: 5
gcode:
M400 # Wait for moves to finish
G90 # Absolute positioning
G0 Z10 F600 # Hop Z-Axis
M204 S1000 # Set homing acceleration (important!)
{% set x_homed = 'x' in printer.toolhead.homed_axes %}
{% set y_homed = 'y' in printer.toolhead.homed_axes %}
# Set homeing current
SET_TMC_CURRENT STEPPER=stepper_x CURRENT=0.6
SET_TMC_CURRENT STEPPER=stepper_y CURRENT=0.6
# Home X
#{% if params.X is defined or params.Y is not defined and params.Z is not defined %}
G28 X
G0 X 150 F9000
{% set x_homed = True %}
#{% endif %}
# Home Y
{% if params.Y is defined or params.X is not defined and params.Z is not defined %}
G28 Y
G0 Y 150 F9000
{% set y_homed = True %}
{% endif %}
Deploy_Probe
# Restore current
SET_TMC_CURRENT STEPPER=stepper_x CURRENT={printer.configfile.config["tmc2209 stepper_x"].run_current}
SET_TMC_CURRENT STEPPER=stepper_y CURRENT={printer.configfile.config["tmc2209 stepper_y"].run_current}
# Home Z
{% if params.Z is defined or params.Y is not defined and params.X is not defined %}
{% if x_homed == False or y_homed == False %}
M118 X and Y must be homed before homeing Z
{% else %}
G0 X 150 Y 150 F9000
G28 Z
{% endif %}
{% endif %}
# Safe Z
G0 Z10 F600
Stow_probe
# Restore acceleration
M204 S{printer.configfile.config.printer.max_accel}

Is this a vcore3 or Minion?

vcore 3
both motors are used to move in X and Y. So you need to adjust the sensitivity because when it homes X it is also triggering Y. This is a very delicate balance for a coreXY machine, and it is why I went with physical endstops

That's done it. I've set the sensitivity on both to 50. Though now having trouble with the Z tilt adjust. Would you know where I would go to change the macro for this to add a line for deploying the probe?
All changes should be in your printer.cfg (see the
USER OVERRIDES section)ugly-tan•2y ago
Thanks
