Well, I looked at all the threads there, but again, unless I missed it, the v1.2c was no where to be found.
I suspected it might be there if I registered for the site and it then it might reveal a "files" area, but today the registration process is/was closed.

I did see info regarding Mach4 and some info for using an Arduino; not really what I am looking for (I don't think).

Thanks anyway.

Maybe the illusive dll will rear its head sometime. LOL!

OK thanks for looking for it as well. I'm familiar with his awesome build site and was one of the first places I looked too. No joy.

Hi Guys,

It was posted but I can't find it either now.  ::)

The attached zip contains version 1.2c of the DLL which is the latest version.

(n.b. although I have made a number of changes to Art's Engraving DLL over the years compatibility between Impact and Laser use has always been maintained).

Thank you!

I got the 445nm 2W laser in the mail and the correct wavelength glasses. Applied 12vdc to the driver board and moved a wooden board back and forth to get an idea of where my focal point was (after playing with the lens adjustment ferrule and getting as small of a dot I could get). Then the beam went dim and I could no longer get any burning of wood.

I checked the back of the power supply again and it was 12vdc / 850 mA. So I dragged out my multi-tester and found it was around 19 volts! Seems though that I recall that the true reading should be taken when under a load.

Now I don't know what do. The fan was running on the end of the laser's case and it never even got warm.

It is giving off a faint blue light but nowhere near what it was for about a minute.

Any testing procedures I could try? It came with no instructions.

 Help?

Sorry to say this but the symptoms you have described exactly match those of a blown laser diode.  :'(

Re: Laser turns back on at end of program

Hi Guys
Have been a watcher on these pages for some time and have learn't a lot, but i am now branching into a laser add on for my bench mill.

Have got the signal to fire and to turn off with the M10P1 and M11P1 commands, no problems, but when the program ends, the unit fires again.
I have gone thru dozens of threads, here and on other sites, tried the suggestions, no luck.

Am using output1 pin 9 active high.
I wish to keep the use of the Z axis for zeroing and focal adjustment, have already  got the screen extras up and running.(that was a fun learning curve)
(Have also tried this on the std 1024 screenset, no luck)

The interface is a DIY LPT breakout, nothing flash, no smarts, and works perfectly.
I have it set up with a series of LED's on all the outputs for testing.
the S.... command is correctly reflected in the Dro.

Below is a sample code i have been using.

Like most when learning a new skill, i have provably missed the obvious.
any and all help appreciated.
Doug

Hi Doug,

Config / General Config / Pgm End or M30 Rewind - look to see if Turn off all Outputs is checked.
