Do you mean yes but still have to build Tweakies board?

you have to build tweakies board, because your BOB creates 0-10V and no PWM as far i can see.

can pin 14 be used where my spindle is usually connected?

Yes.

but then you have to use two profiles or Change pin assignment in Config -> Port's and Pin's ->Motor Outputs ->
Spindle.

btw. are you using the relay on your BOB?

Remind me where to check that?

Forget it, had a look to the layout of your BOB, the NC contact is not connected to a terminal.

a try would be to use a external relay on Pin8 and use this relay to Switch the 0-10V Signal, but im affraid
that the relay switching time will also create burns.

so last Option:
Tweakie has published here: http://www.tweakie.byethost10.com/27_files/Page1020.htm
a small circuit to use PWM and Output for fast switching.
your laser also accepts PWM and you can use Pin 8 and 9 for this.

This is what they said earlier
"Set the adapter back to program 0, then enable inputs are not used. inputs is mostly for advanced use.
This will solv the problem."

sorry i overread this, that's bad, because the only way in Mach3 is to use M10/M11 for fast switching laser,
M3/M5 in combination with S-word is to slow and you will allways get burn marks at start and end.

you can link Terminal 3 (Enable Input 1) to terminal 5 (Enable Input 2), maybe this makes a difference.??

When I run some gcode I get 4.95v between pin 3 & 4 with it wired pin 8 10k resistor from 5v to pin 8 on bob

that's like it should be M11P1 is switching Output and Output gives the 5v to Enable Input 1.
so Mach3 and Output are OK, but laser is not turning ON.

so maybe contacting

contact@optlasers.com

would be an Option, for the Moment i can't see, what we are doing wrong.

4.95v Between pin 3 & 4

but laser is not turning ON?
Mode2?
