Weird z-probing with Kossel Delta-Printer
recently I build my first 3D printer, a delta style printer.
For a few weeks I am having trouble with the calibration.
I calibrated the printer with the paper-method...all three tower and the centre. I think regarding this part, the printer ist calibrated quite accurate.
But when I want to print large parts (200 mm length) at one of the edges the printer prints above the print surface and at another edge the nozzle moves into the bed.
So I want to add z-probing and z-correction.
First question: Can anyone explain to me what z-leveling Exactly does andy why I need it? I have trouble finding any good explanations.
Second question: I have the endstops calibrated with the paper-method, what is the best order to go on now? G28 - G32 S2 - G29?
Third question: As is sad, I am sure having the enstops calibrated quite accurate.
But when I to G32 I get differences at about 0.4 mm what is totally weird in my opinion.
Because I don't have any Idea what to do now I am writing to you.
Hopefully you can help me.
Thank you very much & greetings from Germany.
