/diy/ - Do It Yourself

mesh printing really only needs ~IR range accuracy, actual z probing for multi z axis homing needs the consistency of ~microswitch (no lever) or by hand like duet does for their homing methods (2-5 point homing when z steppers are initiated, loading of different heated beds depending on temp or bed material measured with a removable probe), or you will have first layer issues, but as long as its within .05mm every time, you shouldn't be too concerned. this is true going down to a 0.1mm first layer, by that point you should use a raft.
