Harrison M250

Arthur,

I take it you have read the info here on Tony Griffiths site? Looks quite a nice beast...

[Arthur Kingdon]

Hi,

Yes thanks, I've seen the info on the Tony Griffiths site but it only covers the manual version of the M250. Mine is the manual/CNC Trainer that was used to supply colleges etc. I've been using it for a while in manual mode and the stepper motor on the cross slide does not interfere with such use. It's a good piece of kit and I'd really like to explore it more fully.

I had a quick google for any examples of use but nothing found, although lots of places to buy the manuals... but you have the programming guide already.

So get 'em scanned and I'm sure between Kip, myself and few others we can help you work it out!

Hi,

The scanning is no problem but what is the best way to let you view the pages?

Thanks,

Arthur

Ideally scan to PDF, but if not just scan to tif files and post them here.

Ideally scan to PDF, but if not just scan to tif files and post them here.

Right then, scans done as 96dpi bitmaps and saved as tiffs - size around 100kb, not good for printing but should be OK for viewing on screen. I hope they don't take too long to download.

I have scanned a few pages which I think might be relevant plus the contents page to show what is in the manual.

The uploads just failed - 'invalid files' - perhaps tiffs are not acceptable?

Just tried again after saving files as bitmaps (Windows format) and it seems to have worked. Not sure if mac users will be able to view.

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?
