Bed Levelling using 3 z motors and 1 z probe issues
-
That makes no difference And i have changed it to 0:0, as soon as the P4 starts the process, the motors move the x and y to positions, but on the way the x grinds into the end stop and keeps trying to to move in that direction and not the X30 position, when it goes to the front stepper screw position it then does the same for the Y Endstop until i have to hit the Stop button.

G31 P500 X40 Y40 Z2.5 ; set Z probe trigger value, offset and trigger height
G30 P0 X20 Y300 Z-99999 ; probe near a leadscrewNext issue.
you say probe at X20
With an offset of X40 the nozzle would have to go to X-20 to probe there.same for Y

OK what a twat should have noticed that, thanks, forgot to make notes before update and lost all my config files,
When it finished the probe (after changing to the correct parameters) it does not adjust the leadscrews to make up the bed being uneven ??, it just displays the warning that there are differences that exceed the limits.

Yet again what a savior, I am making notes now as not to get lost, very new to 3.11 so again many thanks for your help.

@dc42 this seems link a bug though. G30 should not allow movements outside of the axis limits

G32 moves my nozzle outside the axis limits when executing.

@dc42 can we get your input here?

From the documentation:
Caution: the XY coordinates are permitted to be outside the normal printable bed area! This is intentional, because some printers (e.g. delta printers) benefit from probing areas not used for printing.

@fcwilt
thanks i did not read that.
