Hi, Chivo.
Change 47K resistors to 10K on CS Out.

By Alan:
Use this equation to work out the resistors you need for your motor's current
limits :-

<resistor in ohms> = 20000 / <current in...

Nice release. :)


I’ve same result the motor not spin. :frown:

Thanks.

Hi Allan.

I use old parts from another board (crap board)
and can’t read revision numbers, sorry.
I bought 3 new PIC’s and its work very fine.

Thanks.

Now is work fine after change PIC. :eek:
With unloaded stepper motor (HT23-400 264oz-in, 2.8A),
I can turn 300rpm without any resonance (8micro-stepper).
Very nice board and firmware. :) ...

Hi all, :)

I have the same problem.

Any idea to solver this?

Thanks.
