Yes, www.bodgesoc.org/lathe/lathe.htmlThanks Andy- Are these available for download somewhere?
However, as I have been saying in another thread, there are rather neater and better ways to achieve that functionality in newer versions of EMC2 (GladeVCP, NGCGUI)

the software is doing nothing.
Tried a different LPT cable, but it didn't make much difference.
I've found that:
Removing LPT cable stops the noise.
If motors are disabled, it seems to stop the noise.
Any clues on this one?
TIA

I now seem to have what is a basically functional machine, but my motors seems to whine/buzz even when
the software is doing nothing.
Mine do too.
The motor are still drawing full current when stationary, but possibly at quite a low PWM duty cycle. I think that is probably enough to create noise.
In other words, don't worry about it.

Ok maybe I can keep the motors disabled when not running a job- assuming that will stop it.
Is it possible to set a 'motor enable' LPT pin for each axis?

However, having used steppers in other projects which didn't have this issue
I'd like to get rid of the noise if poss.

except everything comes out half-size
If I manually jog the machine it moves correctly (i.e x1 y1 moves x 1", y1") but the Axis display shows it
moving twice as far.
All my .conf numbers seem to be correct-I guess if they were wrong x1 etc wouldn't move 1 inch.
TIA
