do we need more than 3 point z probing for big build printer? how to set it up?
I have configured recent firmware 0.92 for z probing, my custom made machine has 500mm build platform ( XYZ 500MM,500MM,500MM) I have observed that z probing does not work perfectly for such a big bed with 3 point sensing ( z speed 2mm / sec with 5 samples each point) .
(I am using inductive sensor PNP 8mm with dual head machine. My XY sensor offset if 85mm and 20mm respectively. )
do i need more than 3 location test for outbid levelling if yes how to enable that in repeatier firmware?
