I upgraded to 1.19 last night, and started playing with the M671 feature, in hopes of making leveling easier on myself. However, I seem to have gotten lost along the way, and hope those wiser than I can explain things.
I have a CoreXY with a 300x300mm 8mm thick aluminum bed, with 4x interface/leveling holes (yes, I know, 4 points is bad. I didn't know better at the time). My Z is driven by 2x leadscrews belted to be driven by a single stepper. I'm using a DC42 IR probe at current for Z probing.
In my config.g, I added in M671 X25:25:275:275 Y75:225:225:75 S1.0 P0.5 ; Define bed screw locations with maximum correction and thread pitch.
(I know that the S1.0 and P.05 are the defaults, and technically not needed, but figured having them there wouldn't hurt, and would remind me they are needed if anything shifts from the defaults). Since I have only a single Z motor, I do not have an M584 defined.
I configured my Bed.G file with:
[c]G28
G30 P0 X25 Y80 Z-99999
G30 P1 X25 Y280 Z-99999
G30 P2 X275 Y280 Z-99999
G30 P3 X275 Y80 Z-99999
G30 P4 X150 Y150 Z-99999 S4

The probing locations (from memory ATM), were chosen to be very close to the bed level screws, but not directly on top, as they are black, and have a different IR response than my bed itself. The final probe point at bed center is because it was previously there (pre 1.19), and I couldn't think of a good reason to remove it.
Executing a G32 runs the Bed.G, and then brings up the height map as I'm used to, and displays offset values for each of the probed points. However, it does not offer any sort of feedback (as far as I can tell) about the number of turns needed for height correction.
So, that brings me to the question part of this narrative-is the printout of turns per screw adjustment not fully baked in yet? If not, where is it hiding that I'm missing it?
On the height map, and the G32 results in the console-are the reported Z values for the bed equation the adjustment to be applied, or the height of the probed point? If it is the height, and not the calculated adjustment needed (in mm), where is the adjustment needed reported out?
Thanks!
