How to make delta calibration

[tirititraun]

First, thank you for the firmware and your work.
I was unable to calibrate. It says deploy probe, that's when i plug the probe in. It does 1 iteration and says stow probe. I don't know what to do if i disconnect probe it says probing failed if i keep it connected, probing fails. I don't know what the process is. Sorry for my ignorance my probe the second type

During the calibration, does your probe actually "click" on this first probe? If not, it is most probably because the height of the delta is set far too low in the initial configuration, no idea why. Probably knutwurst has some modified bed or whatever. You have to increase the height of the delta to 280mm (or even more), then it will work as expected.

However, if you talk about the UBL bed leveling process (the very first step, build cold mesh) - it also fails on my printer after the first probe (probe clicks, drives up, then it says "stow probe")

Hey I'm having similar issue here. After deploying the probe and clicking, it drives erratically upward couple short steps and then freezes for a while and says "stow probe". I had this firmware already flashed but after messing with configuration and eventually clicking "Restore defaults" it started to do this thing. Now I've tried reflashing but that did not help.

So in my case it was loose connection to one of the bed leveling probe cables.
