General Mach Discussion / Re: Power Supply upgrade 24-48 G540 the Bad Pins?

« on: November 07, 2009, 02:30:17 AM »

Sounds to me like you may have blown the pins on your computer port with perhaps too high a voltage getting in there.
Test the parallel port input/output operation using Parmon which can be downloaded from here:-

That will at least rule out one possibility.

To get the best results from Mach, it is like Rich has said, you should use a dedicated PC running Mach and nothing else. This way no problems will be experienced.

There are quite a few explanations for use of the touch plate here on the forum but, if you wish, you can see how I set up my tool positioning here:-

Hope this helps.

Show"N"Tell ( Your Machines) / Re: The Laser Project.

I have now constructed the header/expansion tank (which has been fitted to the rear of the laser tube enclosure) and an inline filter (fitted at the circulating pump inlet). The cooling system has been filled with antifreeze and is being tested for leaks (none so far, but don't hold your breath  ).
I was pleasantly surprised to find that the system cleared itself of the trapped air after the circulating pump had been running for approx. 15 minutes.

Now to make a start on the control electronics.

Excellent work.

FAQs / Re: Enable 1 - red LED on - Why?

« on: November 03, 2009, 08:15:42 AM »

From :-  Config / Ports & Pins / Output signals  you should be able to turn Enable 1 off, by disabling it. That may let your machine work as normal and is worth a try.

Brilliant idea Sam. I just wish I was clever enough to do it. 
I think the best I could achieve would be a blob which may look something like a bell Brett and as nobody has fingers small enough to ring it who knows if it works ?.

Certainly won't be able to cut stainless Gary but it should be OK for thin acrylic etc.

A friend of mine has just had some stainless fabrication work done by a company that cuts the material with lasers. He mentioned that I was constructing my own laser cutting head so they cut me this bicycle from stainless and said that if I could make one like this then I have truly constructed a machine to be proud of. (It is 1mm thick and 5mm long).

Don’t think I will ever be able to do it but it is one hell of a challenge.

I wonder - can anyone else cut one like this on a home built machine?.

Sorry for the bad photo but it is the best I can do without a close-up lens.
