Need Help Understanding M671 Leadscrew Position Values
-
I'm confused as to what the leadscrew values should be for M671. I have an i3 machine with two Z leadscrews. I will be moving the second Z motor over to E1 and adding an M584 to my config.g file. What I do not understand is what the X and Y values are relative to. Are we talking about the screws the hold the hotbed to the Y carriage or the actual Z leadscrews? A diagram showing how to derive these values would be a huge help. Thanks!

They are the XY coordinates of the Z leadscrews.
-
relative to what though? i attached a marketing pic on my printer that I'm putting the Duet on.

The origin is wherever on the bed you chose X=0 Y=0 to be when you set up your homing files.
-
For example a big box might have Z1 at X-35,Y100 and Z2 at X335,Y100.
The Z towers are 35mm of the edge of either side of a 300x200 bed.
The head obviously can't reach the points that are defined (there is a leadscrew there!)
