Calibration

Home the machine in X and Y:

G28 X Y

Position the nozzle in the center of the bed. You will need to adjust the coordinates for your machine.

G0 X125 Y125

Start the calibration process:

IDM_CALIBRATE

You can either use the web interface to adjust the nozzle height from the bed, or TESTZ Z=-0.01 to lower it. Use a piece of paper or a feeler gauge to measure the offset. Once finished remove the paper/gauge and accept the position.

ACCEPT

Save the results to your config file.

SAVE_CONFIG

Initial Tests

Home your printer.

G28

You can test the accuracy.

PROBE_ACCURACY

You can also measure the backlash of your Z axis

IDM_ESTIMATE_BACKLASH

You can now run a Bed Mesh Calibration (I would advise doing either a Z_TILT or QUAD_GANTRY_LEVEL before.

BED_MESH_CALIBRATE

Your Cartographer is now calibrated and ready to go.
