I decided to try new firmwares:
Printing from SD card
220.127.116.11 and 18.104.22.168
It only lets me print once successfully. After the 2nd print when a print is initiated, it homes all axes, heats up nozzle - Goes to above wipe pad. But nozzle does wipe sequence about 20mm above wipe pad, never touching it, so Probing failed, Printer Halted. turn printer off/on it prints as normal. Like 2 print there is a corrupt offset ??
1st print after a reset. It homes all axes, heats up nozzle - Goes to above wipe pad. Wipe sequence succeeds. Goes to touch 1st disc but it just misses it. Rewipes, just misses disc, rewipes. trys again maybe. But then it fails to probe error, printer halted. Its missing the disc by a tiny amount like theres a set limit to the down movement to find dics and it wont try a 10th of a mm farther down.
Yes I restore failsafes and store settings after loading new firmwares
Yes I reenter my esteps and zoffset, and store settings
Yes nozzle is clean
Yes wipe pad is clean
If i revert back to 1.1.19.x it can probe the disc no problem
