Control system for Harrison M250 CNC

[AdrianW]

Ive just installed Centroid Acorn on a Harrison M300. I'd never look at Mach 3 again, not the same league.

Thanks for the recommendation - the Centroid forum seems pretty good so it looks like I'm going to be looking for a decent spindle encoder (it's got an optical HP one that's way under the minimum spec.) and also a VFD that's compatible with the Acorn - if you have any suggestions for one that's not silly money I'd be very grateful. I'm liking the idea that I might be able to do rigid tapping!

Just get a cheap and cheerful Hyangyung one on Ebay. £100 ish and sorted. There is a guy on ebay, near me, selling good quality encoders for circa £45.
