Acorn Zero Voltage on Spindle Bench Test <resolved, leads not making contact>
My com stress test passes, but I dont get any voltage when I run the spindle bench test. I dont have anything else hooked up to the board. Any ideas? I've gone through tech bulletin 270 and all communication test pass. I have ran the PC Tuner App as well and all is green.

Re: Acorn Zero Voltage on Spindle Bench Test
show us how you are measuring the analog out voltage from acorn.

Re: Acorn Zero Voltage on Spindle Bench Test
Hey Keith, I’m following the manual and have tried two different digital multimeters. A Milwaukee and a Fieldpiece. I’ve tried auto and different digit combos, even millivolts. I updated Cnc12 and the wizard. Just for the heck of it reinstalled the pc tuner. As I said before it passes stress test. Heartbeat is on and using shielded Ethernet and com bench test passes.

Re: Acorn Zero Voltage on Spindle Bench Test
I just noticed I took the picture of the Acorn with it powered off. But the multimeter picture is with it powered on and spindle bench test program running.

Re: Acorn Zero Voltage on Spindle Bench Test
You are going to need to provide more info, so someone can help you out. Do a report and attach, explain exactly step by step what you did to command spindle on and spindle speed. Screen shot of spindle setup in the wizard will help. Just saying it doesn't work, won't get a good answer.

Re: Acorn Zero Voltage on Spindle Bench Test
Barring any unusual changes to the PLC program, and assuming you have good contact where the test leads are inserted in the analog plug, and assuming you have steady logic power applied to the Acorn board (i.e. it communicates normally with CNC12), and assuming your meter is trustworthy, then this looks like a hardware failure. You should contact Centroid about sending it in to be tested.

That's a whole lot of assuming.cncsnw wrote: ↑Mon Mar 25, 2024 12:21 pm Barring any unusual changes to the PLC program, and assuming you have good contact where the test leads are inserted in the analog plug, and assuming you have steady logic power applied to the Acorn board (i.e. it communicates normally with CNC12), and assuming your meter is trustworthy, then this looks like a hardware failure.

Re: Acorn Zero Voltage on Spindle Bench Test
Well after messing with it all weekend I finally decided to make some extension wires with crimped ferrules instead of trying to put my test leads directly into the molex connector. Swapped to clip style test leads on the dvm and viola it worked. I guess the grips on the test leads made it go in at a weird angle and I wasnt getting a good connection?? Anyhow, maybe this will help someone in the future.

thanks for reporting back.
we test every Acorn function before they ship.
