Re: [CAD_CAM_EDM_DRO] New drives

Scott;
I don't know the answer to that yet , if I have a gecko
drive I would compare them , but don't forget that this
is a kit , and I believe that gecko drives are still the best
with the best after sales service, Mariss, how can you
manage to do so much and look after people so well?
anyhow the drives are not microstepping or anything
like that , I believe that they are H bridge drivers, better
designed than the old ones , and the constant current
cards are very good, I will try to post a picture of them
tomorrow if they have not put one yet on their web site regards
mariano
