Trigger height is not right, still hitting bed when probing
-
trying to get this trigger height correct. seems any adjustment im doing has no effect. Im assuming i am adjusting the wrong spot..

@frnknstn You don't use a negative number for the Z offset.
Use this: G31 P500 X0 Y25 Z0.757 -
@stephen6309 i switched this and it is still the same. am i changing this in another macro? ```

@frnknstn Make sure the sensor mounted solidly. You can run just G31 to make sure it was set correctly.
In my config.g I set the G31 with Z0 and I use a macro at the start of a print the set the the Z offset. For getting the offset, I use the paper method once everything is up to temp, run my macro, test then adjust it in the macro. Adjust again if needed when making a test print. I use a macros, since it's fast than rebooting.
My PLAOffset macro:
G31 P500 X-30 Y0 Z1.86 ; Set Z probe trigger value, offset and trigger height; increase to get closer M291 P"PLA Offset" S0 T2 -
@stephen6309 just noticed i dont even have G31 in my config

@frnknstn I have that G31 in config.g to make sure a G29 doesn't send the bltouch off the bed.
