Problem with SCREWS_TILT_CALCULATE

[airkingbr]

I performed a fresh installation of Simple AF, and after installing and completing all the Cartographer calibrations, the SCREWS_TILT_CALCULATE command consistently returns a "move out of range" error.

Note that I am using K1 Max with Cartographer and BootyGauntry.

Upon checking the configuration, I saw that the following settings were applied for SCREWS_TILT_CALCULATE:

[screws_tilt_adjust]
screw1: 22,4.3
screw1_name: front left screw
screw2: 278,4.3
screw2_name: front right screw
screw3: 248,253.3
screw3_name: rear right screw
screw4: 48,253.3
screw4_name: rear left screw
speed: 50
horizontal_move_z: 5
screw_thread: CW-M4

This configuration is causing the "move out of range" issue.

Looking through my backups, I found the configuration that always worked on Simple AF; here it is:

[screws_tilt_adjust]
screw1: 19,6
screw1_name: front left screw
screw2: 278,6
screw2_name: front right screw
screw3: 248,255
screw3_name: rear right screw
screw4: 48,255
screw4_name: rear left screw
horizontal_move_z: 5
speed: 100
screw_thread: CW-M4**

Ah so your stepper_x and stepper_y config is different to what is expected.

So your stepper_x config (only relevant values btw):

[stepper_x]
position_endstop: 300
position_min: 0.5
position_max: 300

Your stepper_y config (only relevant values btw):

[stepper_y]
position_max: 300

The default stepper_x (only relevant values btw):

[stepper_x]
position_endstop: 306.5
position_min: -2
position_max: 306.5

The default stepper_y (only relevant values btw):

[stepper_y]
position_max: 306

So the instructions say to substract 2.5mm from the endstop and position_max, add 2.5 to position_min for stepper_x, for some reason I was provided config which is different to that, not sure why:

[stepper_x]
position_min: 0.5
position_endstop: 303.5
position_max: 303.5

[stepper_y]
position_max: 284

So the screw tilt adjust I guess is based on that, so now I'm not really sure how to proceed. I might reach out to other owners of BCJ K1M to see what they have.
