"Probe points must be in clockwise order" aligning z screws

oliof

Hi,
I am converting my CR-20 to dual z leadscrew. The basic setup works, but when I try to follow the wiki instructions for bed leveling using multiple independent z motors, I get an error trying to probe near the z screws to align the motors:

Error: Probe points P0 to P1 must be in clockwise order starting near minimum X and Y

So, I must be doing wrong. Any help is welcome (-:

I am running RRF 2.03

Here's my config.g and bed.g:

The M671 command has not been accepted because you need to specify Y coordinates for the leadscrew positions as well as X coordinates. If you have only 2 leadscrews, one at each end of the X axis, use the centre of the Y axis as the Y coordinate for both.

You're absolutely right! I removed the Y values from the example in the wiki and then forgot to add in the real values for this printer ... thanks!

BTW sometimes it helps to send M98 Pconfig.g from the GCode console, because then you will see any error messages generated when running config.g.
