Hey gang, I'm running Marlin 1.8.3 (and bugfix) on a RAMPS 1.4 board and have run into what I hope is just a mistake on my part.
So let's say I do the usual UBL setup on a new machine
M502
M500
M501
G28
G29 P1
After the probe finishes, I look at my mesh with
G29 T
and see sane values. UBL works great, I'm a happy dude. Now lets say I run
G29 J
to compensate for a tilted bed when I moved the printer or something.
The values in my mesh have now all been doubled and my printer tries to live its dreamlife of being an auger and drills the hotend into the bed.
So I run G29 J again, again the values double. What was originally a 2 lets say became a 4 and now is an 8 .
Is this expected behavior? Am I misunderstanding the purpose of G29 J?
