Smart Stepper?
-
Anybody working on using these with a Duet?
-
I am interested to know how they work with Duet too.

I have been unable to find any user manual or specification for this device, so I can't tell whether it is compatible. I have posted a question at https://groups.google.com/forum/#!topic/smart-stepper/a3IRc89yG5E.

I have had a reply to my question. It looks like you should be able to use the Smart Stepper connected to the expansion connector or to the CONN__LCD connector. Connect the step, direction, enable and ground pins on the Smart Stepper in the obvious way. Connect the VIN pin of the Smart Stepper to +3.3V on the Duet. In the M569 command for that driver, I suggest T1:2:20:0. If you get missed steps, you may need to increase one or more of those values.

it's an old topic but for all who found this: https://github.com/Misfittech/nano_stepper/issues/40
i documented some stuff for wiring up the smart steppers with a Duet 2. Until yet i had no problems with missed steps yet. I did not configure the T parameter.
by the way what are the default values for step pulse width, step pulse interval, direction setup time and direction hold time ?

@vmario89, what are the advantages of having that smart controller between the duet and the motor?

As fast as the Duet can generate them, which is well under 1us. The Trinamic drivers need only about 100ns.
