Dudes Corexy automatic leveling

peirof

Hi,

next step is setup: "CoreXY automatic leveling", usin BlTouch and 3 leadscrews....

i have 2 questions:

1- Offsets of leadscrews, are measured from center of Nozzle. No? They have a limit? one of my leadscrews its near 70 mm from nozzle...
2- The Snn, parameter "Snn Maximum correction allowed for each leadscrew in mm (optional, default 1.0)", what represents?

Thx

S= number of bed screws

There is no limit. The lead screw position is measured relative to the 0,0 point on the bed, not the nozzle.

S for maximum correction allowed is the distance between the highest and lowest point it will try to correct for. You may need a larger value at first if it's very unlevel.

That is true for the G30 command used in the bed.g to execute the probing moves.
