I have no problems at all with Firefox. You could try uninstalling it, cleaning the registry and installing the latest Firefox version.

Hey Dave, how about making a couple of them in wax and sending them (with a bit of cash) to Chris to be cast ?.

Trust 'Hawk Eye' Sam to spot the buffing wheel.

General Mach Discussion / Re: Different use of Mach3 (dispensing)

Just a thought Roman but if the dispensing piston was thread driven (rather than air operated) then this could be operated by a stepper motor controlled by another (possibly the A axis) axis of the machine. This should enable full Mach control of the volume at any point of the work.

Warning label (engraved into traffolite) for the front of the PSU. First time I have tried this, it was 'raster' engraved rather than 'vector' and it took forever.

The new PSU enclosure is now, more or less, complete - just the protective earth terminal and ground strap for the lid and a small EM screen and thats it.

Already tested the theory Sam and Super Kitty can prove it.

Thanks Guys,

Afraid I can't take all the credit for the box. I cut the ally on a guillotine and used a band saw for the cutouts, cleaned the edges to the scribe marks with a sander, then bent it in a V block on a fly press (thanks to a local machine shop). The TIG work was done by a professional (I am OK on SS but you would not want to see any of my ally TIG work  ).

Let you know about the thin foil Dan when the project is finished.

Right on Sam but did you know that CO2 lasers are, apparently, better at burning corneas than they are at retinas because eyeballs are quite opaque at the far infrared (not that it makes that much difference though).

The psu has arrived from China. This unit consists basically of a TV line output transformer capable of producing some 18,000 Volts which is on/off switchable, with a short rise time, from a TTL signal and current adjustable from a 0 - 5 Volt analogue input.
I will need to construct a new enclosure for this unit so that it can be fitted safely to the framework of my machine and this is the progress so far.
