Hello,
So I've purchased (against my better judement) a G2s "Pro".

Firmware loaded (RKMB_G2560) from the repository loaded after building and calibrtating ... then comes the setup for the Z probe..... Probe points are set to withing 2" of the 0,0 origin, and despite apparently completing the G29 probe, the grid ends thus:

19:11:52.678 : -4.68 -2.34 0.00 -0.58 -0.76 0.00
19:11:52.678 : -3.28 -2.09 -0.90 -0.30 -0.56 0.00
19:11:52.678 : 0.00 -1.84 -0.64 -0.03 -0.36 0.00
19:11:52.678 : -3.56 -2.24 -0.91 -0.34 -0.71 0.00
19:11:52.678 : -4.15 -2.96 -1.78 -1.30 -1.78 0.00
19:11:52.678 : 0.00 0.00 0.00 0.00 0.00 0.00

I don't trust the results as the values are far too high in places I know are very level.

The spider does not raise after probing, and just sits above the bed - commands to set z height to 0 result in the head raising to it's full height at slow feed rate, meaning I have to bring it back down to test the probe results - which "look" OK.

However, when a print is sent the nozzles slam into the bed......
