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.

Hi Guys,

Just my thoughts…

I think TPS has suggested reasonable tests to show that the Enable#1 Input of the PLH3D-CNC does not work as defined in the manual.
The actual tests made by Allan appear to confirm that Enable#1 does not work.
Mateusz may be able to show otherwise or suggest a way to make Enable#1 work correctly.
If there is any remaining doubt then use TPS suggestion of an external gating solution such as shown in my diagram here; https://www.machsupport.com/forum/index.php?topic=44431.msg285191#msg285191

Excellent test results 

(CNC Drive also confirmed the commands are supported in the Mach3 plugin)

Hi Allan,

For some reason I have not been able to get the UC400ETH Mach3 plugin to work here so could you perhaps carry out a test and report back.

Open the UC400ETH In/Out monitor (Mach3 Plugin Control) load and run your test Gcode file. Does your Port#1 Output Pin 8 toggle in accordance with the M10P1/M11P1 commands ?
