Bed leveling driving tool beyond limits
-
Hi,
I am finishing the config for a Voron 2.4 using a Duet 3 MB 6HC and tool board
I have the 4 probe points set up,
G90
G30 P0 X0 Y0 Z-99999 ; probe near a leadscrew, half way along Y axis
G30 P1 X0 Y320 Z-99999 ; probe near a leadscrew and calibrate 2 motors
G30 P2 X350 Y320 Z-99999
G30 P3 X350 Y0 z-99999 S4These points keep the probe over the four corners of the bed
M671 X420:420:-70:-70 Y420:-10:-10:420 S5.0
These points are where the corner lifts are
When I run the bed level it mechanically slams the carriage when moving to the X0, Y0 point, trying to drive beyond the limits. It's almost like the G32 command is trying to run the carriage to the points set in the M671 command.
End stops and limits all work fine when just using the move command.
Am I missing something fundamental in what I'm doing?
Thanks

@Joel what probe are you using and what are it's offsets?
You need to think about them when setting your bed measuring points up -
It's an inductive probe has 0 X offset and 30mm Y offset. It does seem like that is the problem. When I move the Y probe point 30mm back it no longer slammed the carriage into the ends. Though I'm curious it would still try to move beyond the limits.
Thanks
