John I feel more like Ray charles but if ya knew how true that was you would piss your self laughing, I'm sat in darkend room with sun glass's on rocking in the corner because I'm so bored.!!
Soooooooooooo much work to do, loads of G-code to create but can't look at the bloody screen for more than 2mins without eye's piss buckets of water.!

Suppose should do what the doc orders and go to Bed but can't bastard sleep for thinking about all the shit I've got to do. .Arghhhhhhh.

984MHz sounds very limited for mach3. I used to use a 1.4GHz AMD for the CNC computer. It appeared to run just fine on 25KHz kernel frequency, but I found when I switched to the 3GHz P4 I could get much higher step frequencies (i.e. feedrates) with the same kernel frequency.

Hi Jonathan - you may be right, although on the Artsoft website they quote 1GHz and 512MB RAM. As a hobbyist with limited funds, I'm not too worried about speed at the moment, but if the machine is a potential source of problems then I'll need to look at it.

I'm still confused by the result of the Artsoft drivertest program and the Mach3 diagnostic page - as I said in an earlier post:
"The drivertest program shows a message 'pulsing too fast' but the pulses per sec show as about 15000 to 17000 where I believe 25000 is required, BUT in Mach3 diagnostics page pulses is always within 10 of 25000. These seem to be contradicting messages?"
Can anyone enlighten me?

Cheers
Ian
