You are welcome my friend, copy anything you find useful.

I have now learned (took a while) that you never stop building a CNC because it is never ever finished -  it is just an ongoing project.

It must be 18 months since I last used the diode laser but from memory it was 10 volts input to the control panel.

Go on get a CO2 tube (ex.MOD), you could do real damage to wood and foam then.

Sorry to hear that.

Is the device lasing ?
Are you sure it is not 12 Volt operation ?

100mV is not ideal but you should be able to burn black colored plastic stuff.

Hi Cosha,

I think that using the lithium pack is a brilliant idea, certainly a clean supply (no spikes at switch on etc.).

The laser has to be focused to the tiniest possible dot (size of a pin prick) to be effective but 1mW is just not enough power. You need at least 150mW to be in with a chance but 1 Watt would be even better.

(I have said this before but please be extremely careful with diode lasers, the beam reflects of almost anything and you must wear protective goggles of the correct wavelength at all times. The wavelength of these devices makes them many many more times dangerous to our eyesight than, for example CO2 lasers.)

Hi Guys,

I am having so much fun with Art's Gearotic Motion that i just had to post another picture of some more laser cut gears.

Thanks for the clarification, I was obviously getting confused.

Would you be willing to share the DXF or PDF version of your cube?

If I can find it, you are more than welcome to the file. It has been a while now since this was done and things just move on.

Anything that saves money has to be good but I think that in most countries it would not be legal to fit anything before the meter as that pipework is the property of the supplier. In turn, I doubt the supplier would want to fit anything that reduced his revenue.     Interesting device though - thanks for sharing.
