@Phaedrux config.g bed.g homeall.g

This should be my config.g, homeall.g, and bed.g

I usually home XY and Z, then run G32 to run the bed.g, and I verified it with paper after it was done by setting it to Z0.00 and it was good. But when I hit start, it's 0.9mm above instead of 0.2mm.

@Phaedrux Question regarding the article for Z probe offset calibrating. I went through the whole thing, and reliably got a Z0.87 offset, even with a power cycle. But now when I go to print, I have to babystep -0.70 to get the proper print height. Any suggestions?

@Phaedrux I see now, thanks for the reference article. I'm using that now to see about proper Z offset.

@dc42 You were spot on with my G31 positioning. This is my first Duet, and I've been a bit overwhelmed moving from OctoPrint to this, but that solved my issue. The Z offset in that same line, is that meant to mean that the nozzle is say, Z2.00 LOWER than the probe? Haven't seen much that clarifies that for me. But how does the Z "trigger" play into that? The BLTouch is so new to me. I'm used to just using paper and turning a knob haha.

Also, @droftarts, front left is my zero (when looking at the front of the machine), and when I move to X0 Y300, the carriage slides straight to the rear of the machine, so that probe point is my back left. Is something set up wrong with that? To me, that makes sense for the XY Cartesian method (from a math graph perspective), but it may not be how it was intended?

Thanks for all the help!

I have a Railcore ii 300ZL, and having an auto bed leveling issue. I've used the setup guide to enter the appropriate gcodes to use G32, set my leadscrew locations, and been trying several versions, but no matter what I enter, when it goes to probe position 2, it always tries to go to Y-30 and smashes the endstop. Any ideas? Current code:

Bed.g
M561 ; clear any existing bed transform
;G1 Z5 S2
;G30 P0 X15 Y45 Z-99999
;G30 P1 X15 Y275 Z-99999
;G30 P2 X275 Y150 Z-99999 S3
;G1 X0 Y0 F5000 ; move the head to the corner (optional)

G28 ; home
G30 P0 X20 Y270 Z-99999 F200 ; probe near back left
G30 P1 X20 Y10 Z-99999 F200 ; probe near front left
G30 P2 X290 Y180 Z-99999 F200 S3 ; probe near right and calibrate 3 motors

Config.g
