Thanks for your prompt answer.
Z axis is refered to third tower of delta printer, not to third axis of piece.

Any tower on my printer give me different measure

Hello everyone!!
does anyone put a duet board on Vivedino/Formbot Trex printer?
If yes, what parameters of speeds and accelerations do you use? because my prints are not good on the corners...

thanks

You should probably start a new thread.

ok, I try it.
thanks

Good morning to all.
Sorry for my english.
I monunt Duet2 + duex5 on my trex3+, configure firmware with originals parameters, but i can't do good prints.
My printed parts are full of ghosting, blobbed angles....

what parameters do you use?
thanks

@engikeneer said in Delta print dimension Issues - smart effector:

As I said before, I doubt this will fix the issue you're seeing with dimensional accuracy, but it may help with getting a better/more consistent first layer.

When I send G30 S1 command, the nozzle hit the bed ang retur ne avery a different value.
If I try some times, I give:
-0.41
-0.43
-0.44
-0.43
-0.47
-0.43
-0.45
-0.51
....

the nozzle is clean. Is it normal to have that differences?

@engikeneer you advice me to delete G29 command into config.g and repeat configuration with G30?

; Use S-1 for measurements only, without calculations. Use S4 for endstop heights and Z-height only. Use S6 for full 6 factors
; If your Z probe has significantly different trigger heights depending on XY position, adjust the H parameters in the G30 commands accordingly. The value of each H parameter should be (trigger height at that XY position) - (trigger height at centre of bed)
