delta tool offset



  • i just finished setting up duet on my delta. i am using an optical endstop with allen key as a z probe. the trigger height is about 12mm above the nozzle. and XY offset is about x-1 y19.

    where do i enter the offset value so the machine would Z0 correctly? is this the G31 command? like if my trigger height is below the nozzle, do i put a negative value or a positive value?

    also, does delta calibration use bed.g? if so, what does mesh compensation use?

    another problem i noticed is sometimes, it would drive pass the trigger height and as the head comes up, it would trigger the sensor from the top. the allen key was designed to be trip the sensor from below as it rises (as the effector moves towards the build plate).

    i have checked that the Pvalue is set to 500 and upon getting tripped, it shows 1000.

    thats fine. the optical endstop is either trigged or not. so 0 or 1000. any value will do.

    set the probe offset with

    z is positive

    yes delta calibrate used bed.g. that is used for calibrating the printer.

    mesh is for compensating for an uneven bed.



  • @Veti following the link above worked. also i think my dive height was too short hence why it didn't trigger. adjusted that and everything is good. thank you
