Harrison M250

Arthur, not stuck my nose in before as I can't help out because many of these commercial controllers are special to the manufacturer and / or machine.
Silly things like hold the prgm key in until it boots then release.

Because it's a commercial control you could ask on the CNC machining page on Practical Machinist, there are some knowledgeable people there and few UK posters who may have had M250 experience.

Hi John,

Thanks for the input - the Harrison flyer states 'The CNC control has been specifically designed for this lathe and its training applications' so you are correct in suggesting it may be special. I'll post a question on the Practical Machinist site - I can't be the only person using one of these, surely?
