Have you measured the voltage across the PWM terminals on your board to make sure you are getting voltage between 0 & 10-ish volts and that that voltage changes when you give different S commands to...

When you say same issues, which issues are you specifically having? That way I can try to help. Also, I have the C11G, not the C41S, board for what it’s worth.

I got it all to work! Thank you!

I fine-tuned the pot on the board to output max voltage and that calibrated 12000 RPM to about 5v. The board outputs about 10.5v at 24000, but my VFD caps out at...

Arturo, thank you! A combination of your suggestions worked and now both the jolt issue and the PWM issues are fixed and I can start and change spindle speed with Mach3!

Only 2 lingering issues...

I'm hopeful and thankful in advance for any help provided. I have a few issues after setting up a new C11G in my system.

My Current Setup

- Custom 4 axis CNC machine with stepper...

Thank you Arturo! Makes very good sense and helps very much!

Arturo, thank you for the detailed responses. A follow-up question:

So if I have multiple E-Stops (or even just 1 routed to the EN terminal) I don't need the jumper between 5V and EN?

Hello!

I've been reviewing the owner's manual and example configurations off of the C11G product page ( https://www.cnc4pc.com/c11g-multifunction-cnc-board.html ), and am a bit confused on a few...

Arturo thank you for you help! I think the C11G is going to be my best bet, but I appreciate all of your advice and help. Placing an order now for the C11G.

Arturo, thank you! A few more follow up question:

(1) Would it be safer for me to go with the 5V power supply from you...

Hi! I am looking to upgrade my current CNC setup and hoping that someone more knowledgeable than myself can help answer a few of my questions below. I have tried to reach out to CNC4PC but their...
