[M350] microsteps for external drivers

[o_lampe]

I'm driving some external TMC2225 drivers from the expansion header of a Duet2.
They run in standalone mode and are jumpered to 1/32 microstepping.

How should I set M350 and M92 for these drivers? I can't set them to 'fullsteps' , since RRF seems to think they are TMC2660.
I've set them to 1/32 and adjusted M92 accordingly.

I'm afraid RRF will try to talk over SPI to them and freeze.
How can I tell RRF these are external drivers? The wiki about the expansion breakout board doesn't mention anything about microsteps.

One more thing: the motors run fine, but they ignore M84 and M18. They are always enabled...
Enable polarity is same as TMC2660 (M569 P5 R0 T5:5:5:5)

I could sort out the enable problem, but the main question is still: how do I tell RRF, these drivers are not TMC2660?

@o_lampe with my CNC i not used any M350 command. only the M92 for configure of the Steps

@o_lampe assuming that you don't have a DueX connected to the Duet, RRF will know that they are not TMC2660 drivers. Just configure the microsteps/mm value in M92.
