Bloody hell indeed. Where are you in St Annes? I'm on Beach Road, overlooking the duck pond.

To be honest I can remember
I know it was a Nema 34 and I bought the biggest I could afford as I couldn’t find any guides to what I needed hence I thought bigger is best. For the same reason I went close loop
From memory about £130 for the motor and stepper driver
Boxford is 1974 on its original cabinet stand with 3phase drive motor now running via a 2.2kw vfd all under cnc control
Running on mach3 on pokeys

Well I'd agree that's logical - but therein lies the problem. Ideally you wouldn't have two different standards of logic in one marriage....

So far at least my marriage has remained continuous and unbroken for the best part of 30 years, so perhaps we've found a middle way that works.

I bought a Bridgeport a few years ago when we were living in Canada (it followed me back to the UK of course). My wife had to walk past it each day to get through the garage to her car. Finally, after a year or so she asked me when I'd bought it, as if she'd not seen it before. She has absolutely no idea what a machine tool is for or even why anyone would want one.
