Hi,
For some time, I had a strange problem: Whenever I used G29 for mesh leveling, I was getting very similar maps, even though I was making radical changes at the bed leveling screws. I couldn't understand why these changes weren't affecting the height map, then today I have realized something: When I issued a horizontal move command from the panel due, the Z axis also moved. I didn't expect this behaviour. I thought that the corrections created by mesh leveling were only active during printing, but it seems that they are always active after you create a height map. This seems counterintuitive for me, as whenever I issue a new mesh leveling macro, the compensation is applied during probing, which results in a facit loop, where there always is the same amount of slope (reflecting the already recorded height map). Shouldn't leveling correction be only active when printing? Is there a command that I can add to config.g to prevent bed leveling being active when not printing?
Here is my mesh leveling macro, in case I am doing something wrong (I use BLTouch as the probe):
G28 XY;
M280 P3 S10 I1;
G28 Z;
M280 P3 S90 I1;
G1 Z5 F80;
M280 P3 S10 I1;
G29;
M280 P3 S90 I1;
