Re: What does everybody use...

Hi Jon,

I'm new to the list, this is the first message received. As I have missed the previous messages, I'm wondering if the extra
boards you have made are for stepper motors or DC motors with encoders.

I currently have an AHHA setup (4 axis) on a small bed mill but am interested in obtaining another set of motor drivers and
motors for use on a small lathe. The AHHA software and board issues step and direction signals oa TTL level. Would your boards
be compatible with this?
