I'm a Newbie myself, and a million miles away from you Tom, especially in the snow and riding two wheels!
I havent got a clue what DSp is, but a two second google found this site.DSP Control Group Inc. - DSP-Based Motion Controllers
Question, is it one of them? if so what model? and have you read the destruction sheet?

If all else fails read the manual, post the info about what the machine is , model , spec etc, with as much detail as to what the issues are? and I'm sure someone on here, (even me) might be able to assist.

But as it stands , My magic wand is Kaput

Regards
Rick.
