SOLVED Points S0 and S1 must be in clockwise order...
So... I'm trying to get independent lead screw levelling working, which I did have working before, but on the new board... I get that message with the exact same macro that I was using before.
Obviously, I've changed something.
I can use the commands to report the relative distances, enough to tell me what I need, ,but I cannot get it to make the adjustments. I don't know what I've forgotten to set.
I do have the M671 command for the motor positions defined.
G30 ... S-1 will report the relative positions and deviation, but of course doesn't correct for it.

I haven't cleaned up the comments in that, but it's pretty close to the example in the wiki.
I'm in the process now of updating to firmware 3.1.1, since I'm re-doing a lot of stuff anyway. The board has 2.05.1 installed now.
Based on your config, your first probe point should be for the motor connected to driver 2. Do you have your z motor cables swapped?
I've switched the probe points back and forth, this is where they're at now. I'll swap them again. I don't even remember which motor is currently connected to which drive.
Well to keep it straight forward connect the left motor to driver 2 and the right motor to driver 4, then your M584 Z2:4 will match the positions of M671 and then your points in bed.g should match as well.
Well, that didn't help.
Macro now looks like:
G29 S2 ; Clear and disable mesh compensation M561 ; clear any bed transform G28 Z G30 P0 X35.0 Y137.5 H0 Z-99999 G30 P1 X185.0 Y137.5 H0 Z-99999 S2 G28 Z
I'd be willing to mae that line a diagonal if it would help, but I can't help but thin that I've just missed something in the configuration somewhere.
@droftarts Keen eye!
That would be a problem, yeah... No idea how the heck that got there, when I was copy/pasting the file from the one that worked before...
So yeah, it works. You'd think that an old Fortran programmer would know to check punctuation.
@SupraGuy great, glad that fixed it! I should probably test what M671 reports when set like this...
