Triple-z G32 true bed level question
-
After it does the initial height measure in the middle, it moves to the home corner (X0, Y0) and crashes. I have set correct Z-probe offset and bed size. Not sure how to correctly set M671.
M584 X0.1 Y0.0 E0.2 Z0.3:0.4:0.5 ; set drive mapping M671 X1:1:271 Y269:43:167 S50 ; set z drive coordinatesThis how it set right and it crashes in the corner. I've entered the values in order from how the Z drivers are set up in M584.

@Velvia sys/bed.g file controls the bed levelling. M671 controls where the pivot point of the leadscrews are. See https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_auto_levelling
Please post your bed.g file, firmware version and hardware version.

@droftarts I completely forgot about bed.g

@Velvia When you say "it moves to the home corner (X0, Y0) and crashes" what actually crashes? Does it crash in X or Y, or is the nozzle too close to the bed already? I see you have G28 in bed.g. Does it lift Z at the end? Post your homeall.g as well.

@droftarts XY crashes, Z is fine I think. I reset the printer before anything else happens.

G30 P0 X3 Y10 Z-99999
G30 P1 X290 Y10 Z-99999
G30 P2 X157 Y280 Z-99999 S3I think you just need to adjust your probe points.
I would suggest you manually jog your print head to place the probe where you want it and then note the current XY position and use that.
@Velvia said in Triple-z G32 true bed level question:
M574 Z1 S2 P"io3.in" ; configure Z-probe endstop for low end on Z
M558 P5 C"io3.in"This is also wrong. You can't use the pin name twice. Luckily for you Z1 S2 doesn't even take a pin name. I would suggest you just remove that M574 Z1 S2 line entirely as it's not needed at all.

@Phaedrux Thank you!! I'm now on the right track, just need to fine tune it.
