OK... I didn't know about the 3 !'s I'll get rid of that. Thanks!
I don't believe a G90 should deactivate the UBL Bed Leveling. Did it come back on after a G91? I did a quick test and it seems to be active in both Absolute and Relative mode.
Try this: Do a G28 and move the nozzle 2 or 3 mm above the bed. (Because if the nozzle is above the Fade Height, you won't see any correction)
Tell PronterFace to move close to the edge of the bed on the X axis. And tell it to go about 1/2 on the Y axis.
Then give the system a G29 A Q 1 M That will insure UBL is turned on and it will load a test pattern for the Mesh. It will be a diagonal line 10mm high going across the bed. A map will print so you can see the pattern.
Tell PronterFace to go up 1mm. That will generate a new fade scaling factor.
Now move from one side of the X axis to the the other side of the bed. You should see the nozzle rise in the middle of the bed. It doesn't matter if you are in Absolute or Relative mode.
