DM542 to 6XD

[soare0]

Fortunately, DM542 were on the original machine I am refurbishing, and the motors too, so tuned and wired.
RRF did a good job, but still, the motors would not move, even if the wiring was right.

The most needed change was R0, wich was not by default present, so the drives were locked at startup.
The timing is set so big, just to be ... cautious (as they did not work at first), it will be tuned later.

; Drives
M569 P0.0 R0 S0 T25:25:50:0 ; physical drive 0.0 goes forwards
M569 P0.1 R0 S1 T25:25:50:0 ; physical drive 0.1 goes forwards
M569 P0.2 R0 S0 T25:25:50:0 ; physical drive 0.2 goes forwards
M569 P1.0 R0 S0 T25:25:50:0 ; physical drive 1.0 goes forwards
M584 X0.0 Y0.1 Z0.2 E1.0 ; set drive mapping
M92 X80.00 Y80.00 Z400.00 E420.00 ; set steps per mm

I expected that R0 in M569 would be the default value, but it is not (and RRF does not set it anyway in config.g), so...

This is only an observation, not an issue (anymore).
