As you can tell I am new to steppers!
But what would make a stepper driven by a PicStep driver smooth in 1 direction but rough in the other?

Hi all, :)
I have the same problem.
Any idea to solver this?
Thanks.
Someone - help these guys out!! (just a post bump to help out!!)
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. :)
Thanks Alan.
Hi, Glad you figured it out. I've been busy and not looking around the forums much these days.Quote:

I've used 30 or so 16F628As and never had any issue, but globally you never know!
Cheers,

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.
if the motor workes fine in one direction and the the other the only think ( i think ) it can be is software in the microcontroller or pc software ( that is if u r using a 4 pole stepper, if it is a 2 pole it coule be the above plus a flakey drive transistor
