Set your top speed to 10000
And your low speed to 0

Then go into MDI and type
M3S5000
And read your meter?

The top pic with the meter is all i can get it to come up with 0.02

I can't tell from the photo, but are you sure your meter probes are in the top two holes?
Cheers,

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

Test your meter against a known good DC source and make sure it's ok.

I believe you have the red lead plugged into the wrong jack on the meter....should be the jack next to COM(black)

Again, test your meter with a known good DC source like a power supply or battery.

(picture of CNC12 screen with MDI prompt open; spindle speed showing +5000 RPM; OUT7 green; and W7 = 2047)

That helps considerably. Having PLC variable W7 equal to 2047 should closely correspond to having 5V on the analog output, assuming that the DAC configuration DIP switches on the Allin1DC are set for the 0-10V configuration.

Are your SW3 "DAC SETTING" DIP switches set OFF ON OFF ON OFF? It should be a blue DIP switch block, with ON being down towards the board.

Check the +12V and -12V outputs of your logic power supply (measured from V2 to COM, and from V4 to COM). I am pretty sure that failure to supply plus or minus 12V would prevent the DAC from working.

Call up the Alt-i display again; press F12 three times to get to the page with OUT241-OUT320 on it; then go to the MDI prompt and run M3 S5000 again, so the conditions are the same as in the previous picture. Are all of OUT241-OUT251 green, and OUT252 red?

Did you snug the terminal screws down gently on your test leads, to be assured of a good connection?

I think Marty has it. You have the meter set to measure Amps, not Volts.

Ok I`ve done all the tests you asked all voltages read from the test.
the meter was an over sight the logic power supply V4 com = -12.00v V2 com = 12.93
i`ve included I.O pic
i can get 0.47 from the meter now.

Are you saying the spindle test went ok?

I`ve managed to do it now i had to change the spindle speed back to 3000 so all the voltages came up.
