Manual z-probing & bed leveling
I just switched from Marlin to Repetier and gotta say, I am VERY impressed with the software!!! I think I will stick.
When fiddling around with my Delta printer (Folgertech Kossel 2020 RevB) I came to the conclusion that the inductive z probe is aaaawfully way of. It measures my bed with a deviation of ~ 0.3 mm (compared to manually lowering the nozzle to the bed with paper method - at the same position the sensor was measuring). I think its because of the PCB below the aluminium bed or something like that. So no z probing, auto bed leveling and bed correction for me right now. I want to switch to a retractable JCRocholl style z probe later on, but I still think the following would be helpful to a lot of people without z probes (and/or to confirm auto measurements):
Why not implement a "manual z probe" mode? I.e. the head moves to the measurement point and the user lowers the nozzle until it barely touches the bed and confirms to take the measurement now (in software, as G-Code or on the controller board). Rinse and repeat for other points. This should result in a way more precise leveling / correction compared to inductive probing.
Hence, just a proposal. I gotta admit, I am VERY new to Repetier and didn't even donate yet. I am gonna but want to try it out a little bit more before doing that.
