Upgraded the "computer" to a biostar motherboard and AMD 64 about 2.4g.
G0 moves the axis, G1 won't move at all....no errors (I'm not using feedback of any kind, 1 axis driller). Readout moves, axis won't.
I put it on another computer and it works fine. I'm sure the configs are identical. Has anyone had problems with certain hardware acting goofy?

Sounds like the new computer has a 3.3 volt lpt port

Can you elaborate?
-
Older parallel ports used to work on 5v but some of the newer ones cut things a bit fine and only use 3.3v. If this is your problem you can get a PCI port and use that, most of them are 5v.
Do you use a breakout board? quite a few of them will boost the 3.3v to 5v.

OK Thanks for the tips, no I'm not using a breakout board but a second port I think I'll try. I've looked up and down and unless someone here has buddies at Biostar in Taiwan I'll have to measure the voltage!
-
OK That didn't pan out. I ended up in "sherline half pulse mode" and it started working. I realize this has nothing to do with the software but any input? It had been working for months on a slower computer without that feature enabled.

O boy that is not cool ...
you were on the edge of not having it work the whole time... Your drives needed to have a longer step pulse I think...

That's what I was thinking and the only reason I got away with it for so long was it was on a slow computer originally. Well anyhow it is working now so all is well.
It's a real simple machine, a single axis driller. Here's the little screen I came up with-
