M569 R parameter ?

Pseud3mys

I try to configure an external driver connected to duet3 with the 1XD extension.
everything is working exept the R parameter.

R0 = active low

But when I put this:

M569 P40.0 S0 R0 T2.6:2.6:0:5

the en+ pin is at 5v (at High level) when I connect it. So the driver is disconnected. But without (so the en+ pin of the driver at low) everything work.
Why the en+ isn't at 0v ? And how I can fix it ?

thanks !

Maybe the duet 3 disconnect the driver by default ? But I didn't find any command to activate it.

The ENA inputs of many external drivers disable the motor when the are energised, instead of enabling it as you might expect.

It work now (don't now why). The M18 (Disable all stepper motors) command is supported but not the M17. Why ?

@Pseud3mys said in M569 R parameter ?:

Nobody has asked for M17 to be supported before. I have added it to the work list.

RepRapFirmware enables drivers automatically when you try to move them.
