ok.........how does any form of auto bed leveling work with no probe?
You really should have a Z-Probe. But In UBL you can get perfect correction by doing a G29 P0 which sets the entire mesh to 0.00 mm. And then do a G26 to generate a test pattern. Then jump back to G29 and do a G29 P4 R to edit each mesh point.
After 3 or 4 iterations... You will have a perfectly tuned mesh even though you do not have a Z-Probe.
