There is a couple old 80's vintage cnc mills that are coming up in a auction soon and I am considering as a project to retrofit to mach3 controll and gecko drives. There is tons of info on old Bridgeport cnc upgrades but nothing I could find on these.

Excello 604 cnc mill 1982 w/ dynapath 10 control, 3hp bad controller

Excello 605 cnc mill 1985 w/ dynapath 20m control, 3hp working conditon

Tree 325 cnc mill 1987, 2/ dynapath delta 30m control, 5hp, working condition


The tree is probably larger than what I want for my hobby use in the garage. I can find no info at all on the excello units.

What I am wondering is.... are they servo or stepper motors? Motor info that would assist in considering a retrofit to gecko's and mach3. Any other info such as spindle taper (ad says morse 30 which I assume is wrong and means cat30).

Any info at all on these beasts would be most appreciated. As mentioned, the end use is for hobby use in the garage.

Thanks!
