The Mach3 Write Wizard should enable you to make your badges.

There is a brief tutorial on using this wizard here;  https://www.machsupport.com/forum/index.php?topic=35633.0

For others that follow and just to tie up any loose ends…

The 74LS00 gate system mentioned earlier has now been tested and it works correctly with the OPT Lasers PLH3D-CNC adapter. However, another, unforeseen issue has arisen with the Mach3 Plugin for the UC400ETH motion controller. There appears to be some unwanted delays in the M11Px / M10Px switching times which are preventing acceptable laser operation. As Mach3 is now obsolescent (with development ending some 6 years ago) I would not expect any motion control manufacturer to spend any time working on their Mach3 plugins so this particular project has unfortunately come to the end of the line.

My opinion…
With the UC400ETH Mach3 plugin not working correctly and the Mach4 plugin not yet supporting the M63Px / M63Px commands (although I suspect it is not far away) the only sensible option, to have a laser equipped machine fully working today, would be to change the machine control software and use an alternative motion planner which better supports laser operation.

Hi Fred,

Don't rub it in, it's Brass Monkeys here in London

It can if you rip out the existing control board and replace it with one that is Mach3 compatable.

Hi Mateusz,

I can see how your circuit would work but perhaps using BoB Pins 8 & 9 for the Mach3 generated TTL level M11/M10 switching and PWM signals. There would be no problem in changing the logic state of the M11/M10 signal.
Obviously your circuit would have to be tested to prove it operates correctly but I have every confidence.

Hi Allen,

I think we have established that the PLH3D-CNC Enable#1 does not work so an alternative as mentioned by TPS is perhaps the way forward.
I suggest that within Mach you change the Spindle Step Pin# to 9 and use that for your PWM rather than the BoB Pin 14.

You don’t really need a board as your BoB can provide the necessary +5V so you could just connect wires to a 74LS00 chip then insulate the connections with clear epoxy or fit it into a small box or whatever. The circuit would be something like the attached diagram. (The wires should be kept as short as practical to avoid the necessity for additional components).

Once you have it working the Mach3 Active High / Low state of the various signal pins can be changed if necessary.

If you post your .xml file then your Mach3 settings can be checked and hopefully the problem found.
