The default M3, M4, and M5 macros are set up to trigger the "SpinFwd" and "SpinRev" relay outputs which should go to the VFD's "Run Forward", "Run Reverse", or "Run" input.

From your description, it sounds like you are manually triggering a "Run" or "Run Forward" input.

I believe everyone ...

What do you mean by the "onboard outputs"? Do you mean the outputs on the DB25 header? Are you using an older revision of the Acorn?

If you are using the output on the DB25, that should only ever have 5V DC across it. Are you trying to save a relay on the relay board? It won't work like that ...

Thanks Shawn! I would never have guessed that from related posts, but I will take your word and go with the wiring diagram without the c86accp. Working with clearpath for right sizing, but not a straight forward process, at least for me!

I'm currently using 10 year old nema23 steppers and I ...

Now that I've had everything working for sometime, I've decided to upgrade my older basic stepper motors with some new Clearpath closed loop servo's. I've located documentation and it should be an easy plug and play with the cnc4pc c86accp board with my new Acorn board.

I thought at the same time I ...

I'm guessing something is not wired or programmed correctly. I've never seen a VFD that requires the user to manually close a contact/switch or anything else to make it run.


Yes, I'm sure you are correct.

I can change parameters on the VFD so the spindle turns on once the VFD gets power, but ...

I am up and running. Still need to finish my tool touch off and homing, but I am fully functional. It was an enjoyable project and I learned alot which I will use on my next projects. I really like the product - so much better than the previous setup. No longer a MACH3 black box. Thanks to all for ...

Bill, M3 starts the spindle by activating the Acorn relay output you have set to SpinFWD and M5 turns off that relay and stops the spindle. No external switch is needed for spindle control.

You should not be using any 12v signal from the VFD. Acorn supplies the analog signal of 0-10 for speed and ...

It would be really helpful if you post what wiring diagram you are following and also a link to the VFD manual. The pic of the manual page in your album is very blurry. Please upload a better pic or share a link to the manual.

As Centroid467 stated you assign one of the relay outputs to "SpinFWD ...

Almost done with my upgrade and hopefully ready to do some test cuts tomorrow or Thursday. I could swear the (cheap) stepper motors are running smoother and quieter with Acorn vs the old Warp9 / Mach3 setup - is that possible?

I just need to finalize my tool touch off setup, homing and motor ...

One question for Shawnm - I did purchase the tool touchoff from amazon you mentioned (link above) to replace the conductive tto I currently have - how did you wire that up? Looks solid especially for $35 - but no instructions included.

Almost done putting everything back together.
