Hi Jazz
I'm always glad to hear of someones own experience of an electronic piece of equipment. My cnc machine is going to be mainly used for carving wood, guitar making etc. Is the improvement in a closed loop system worth the upgrade? I've got the parts Leadshine MX3660 , steppers are https://www.upload.sorotec.de/doku/m...T6018L3008.pdf and an AXBB-e controller. If it's worth it in performance I would upgrade as I haven't put the machine together yet and the time saved as opposed to removing the motors and upgrading later would be worth doing it now rather than later.
Cheers
Andrew
