independant z axis steppers, for bed leveling
-
Yes that should work, but in RRF3 it's even easier in that you don't need to split them into seperate axis.

r in that you don't need to split them into sep
i messed with v3xx two times, and both times we could not get them working, so i want to get this 2xx working as a fall back when i try 3xx again,
your help has been incredible, and i have gotten further in the past 2 days then in the past month combined
if i can bother you for 2 last items i will get out of here and on to cutting some aluminum for the printer.
i have 2 files left that im trying to get to work without errors, and more towards automatically saving the new probed values
and secondly with the hotend thermister code.;calibrate bltouch get z offset.g

G30 S-2
M500 P31; save resultsI don't think this is doing what you think it should be doing.
Please post your config-override.g to see what it's actually saving.
Using the manual probing to set z0 is fine, but it's not going to set the bltouch trigger height.

so place M500 as the last line in the probe offset macro ?

Well to calibrate the BLtouch I think you'd need to do a G30 S-3 after switching back to the BLtouch probe with M558 P9.
Using M558 P0 to set Z0 manually is fine. You could also use a M291 Z1 to just pop up a jog dialogue for z followed by a G92 Z0.

0_Auto Probe Trigger Height Assist.g
Here's an example of my macro, it's not automated, but might give you some more ideas for use in yours.
M500 P31 is correct for saving the offset, I just think you need to be in the correct probe type before measuring and saving.

Well you're missing the step where you manually touch the nozzle to the bed and set Z0, without that you're not accurately measuring the probe z offset.
You should also add a M561 command at the start to disable any active bed compensation.
