UPDATE....
the touch plate common and the E stop common are in the same terminal block. the -24 common from a power supply is providing that energy to it.
for some reason when the touch plate closes it sends that signal through the terminal block then through the e stop back to the Acorn board... I think i developed a new way of wiring. When the touch plate closes, input 8 LED is changing, but not a solid RED color, still has some green to it. like a low current.
so not sure if i have a bad terminal block, bad e-stop or bad power supply.. but hey im getting somewhere!!
Touch plate sets off e stop

Re: Touch plate sets off e stop
I have searched for stray voltage, I have none, I have wired this correctly the Acorn is still setting the e-stop for the touch plate. I have no idea what is left to check. is the Acorn board bad?
if I have the e-stop set at NO the touch plate works fine. I can say I am lost now. before changing the drivers all worked fine, the wiring all stayed the same the parameters in wizard all stayed the same. now this
hopefully CNC Keith will chime in on this one

Re: Touch plate sets off e stop
What are you using for wire to the touch plate? I use twisted pair shielded cable. I find that it often makes electrical noises go away with sensing devices like limit switches or probes.

Re: Touch plate sets off e stop
Remove your estop and touch plate wiring. Install a jumper wire from DC COM to estop, set to NC. Use another jumper wire from DC COM and touch the input set as tooltouch triggered set as normally open.
What are your results?

Re: Touch plate sets off e stop
Gary,
by doing this the cnc12 has the estop detected being its set to normally closed and not plugged into the input, but when i use the jumper to the input for the touch plate the acorn goes from red to green on the touch input. hopefully i did it correctly

Re: Touch plate sets off e stop
With the wire between com and input 8 and the estop set to normally closed you should show Estop triggered when wire is removed. IP led should be red with wire off and green with the wire connected
Re: Touch plate sets off e stop
Now, with the jumper installed from 0VDC Common to INP8, so that INP8 is green, try touching a separate jumper from 0VDC Common to INP7.
When you do that, does INP7 turn green? And does INP8 remain green?
That is all your original wiring should have been doing: your emergency stop button, when not pressed, should close 0VDC Common to INP8. Your tool touch-off device, when triggered, should close 0VDC Common to INP7. Try to figure out how, schematically, your original wiring is different from the jumpers in this test.

Re: Touch plate sets off e stop
cncsnw,
just performed your test, and still turning input 8 from green to red. its not changing or setting the touch plate input at all.

Re: Touch plate sets off e stop
If you were to remove all the wires from the board with the exception of power, those 2 jumpers and the 24+ to the input banks, are the results the same?
