hello,
I am using 16x16 ball screw and 100 steps/mm accuracy so that for 1 step=10um .
if G code G1 X140.010 so it's generate 1 step for .010
but if G1 X140.012 and G1 X140.017 for that how it's work
if any one know how it's generated position accuracy for these two please let me know

@phaedrux said in 1XDs- Expansion boards not functioning:

And you found that the same wiring, etc was working correctly with other boards?

yes
around one & half month ago.
From Duet3d.

hey,
During SW flash, it was found that 2 of the 1XDs- Expansion boards are not functioning.
1) The Red - status LED does not glow at all, on providing power and CAN signals.
2) does not communicate at all at default 122- CAN address.
& i also try with B120 ,B121 but its not working.

@dc42 @T3P3Tony can you replace the boards?

@phaedrux My question is that after the bed probing firmware gives lead screw adjustment value so how does lead screw adjust based on that value {such as taking one value (-0.074) as reference and adjusting other lead screw accordingly} ??

Hello
Is the lead screw adjustment based on this value ?, the value is as follows:
-Leadscrew adjustments made:(-0.074,0.006,-0.002,0.027)
-before (mean,deviation):(-0.017,0.013)
-After (mean,deviation):(0.00,0.00)

@jay_s_uk @achrn thank u
