I have successfully used Dmm tech servos with linuxcnc, but it was with the older drive before the dyn3, I can vouch for the motor's though, they are very well built, quite and durable. I actually spoke with the lead engineer at IMTS this year. I made it a point to go there. Don't be fooled by the size or lack of reviews. I have had nothing but good experiences, they are always happy to answer questions. They even double checked my calculations for the size of the motor i needed.
