Ive got the 300w dmms and my friend has the bigger ones with internal gearing. He is really happy with them. So powerful he said he bent his router a bit with them haha.

I was at hui's house last weekend picking up some extra lmit switches and called him with questions a few times and he has always helped.

I used to have an md001 and I would just run the nema 34 1000w motors direct drive. That would be a nice simple setup.
