In an attempt to narrow down the problem and decide if it is software or hardware related.

Download and run Parmon http://www.geekhideout.com/parmon.shtml this will establish that Mach is configured correctly and that you can in fact write to and read from your parallel port.

Just a thought but have you tied the 'Enable' pin to +5 Volts [X8 on the C10]  (if you haven't then all output pins will be at ground potential).

Just a bit of further information regarding feed-through capacitors.

As George has said these are ideal for use in series with the AC line cord but they are not suitable for any DC signals, they are purely AC related devices.

That's the way to go Scott.

Please keep us posted on your progress (photos would be nice) - you will get plenty of help here if you need it  ;)

Nice variants on the theme you have made there Steve.

Marcel started me off on this cube thing and I thought I could make just one, but once friends see it - they want one as well. So just keep making more than you need Steve.  ;D

Hi Dan,

I don't think CO2 lasers are too good with metal unless it is somehow surface treated (It's something to do with the wavelength of the beam that makes metals into damn good mirrors) anyway it would take a lot more power than I have available (probably kilowatts) especially for copper foil.
I think that YAG lasers are preferred for the metal stuff.

Thanks Jammerm - the memory of Jacko sure lives on.

Hey Dan,
I forgot to post the close up picture of the striations in the acrylic. I think that there are techniques which produce better results than I have achieved here but then I will just have to keep practicing.

General Mach Discussion / Re: Probe Installation Problems!!!!!!!!!
« on: May 27, 2010, 11:56:48 AM »
Hi Rick,

If you are connecting your probe between pin 15 and +5V on the C11 BoB then you will need to set the input configuration jumper (on the C11) for pin 15 to 'pull down'.
(The C11 manual gives a probe example where it would be connected between pin 13 and ground ... in this case the input config jumper would be set to 'pull up')

Hope this helps.

I always ask silly questions, but why do you have MaxCL enabled ?.
