I'd go down the foolproofed route with M3 and M4 controlling each side of a properly interlocked motor reversing contactor. That way the problem you describe is impossible - You can have either or neither, never both. pop this between the drive and the motor and you should be good.

I much prefer hardware solutions. They're easy to troubleshoot and they rarely if ever crap themselves and go mad.

I had a similar question which could have a similar answer - I need an output to come on when the "Start cycle" LED is on, so that the output is high while a program is running, it's for a slideway oiler.

Just one more thing - Looking at Mach3 and the UC300ETH, I can't see a way of getting mach3 to see more than two ports. Can it be configured to take advantage of all the available I/O in a UC300?

if it's anything like Mach3's command set you'll have a couple of possible jog commands; one starts the axis running and lets it run until it is stopped, one is a jog-while-held command. You had the wrong one?

To tell you the truth, I'd be much happier programming a simple part like that by hand. I bet you could do it in under 30 lines including the comments and you'd have a much nicer time de-bugging it.

Straightforward, strong and reliable - just the job.

I'd just write it by hand, but then I write everything by hand.

In fairness to Microsoft i think we're the only ones still using it, unless anyone else knows better.

the official line is you should go for Mach4. I would support this purely on the grounds of future-proofing as Mach4 is altogether a more sophisticated and capable product (As far as I've seen). It's almost a complete rewrite with very little of Mach3 carried over. So yeah. mach4  ;)
