Uccnc, AXBB-E and VFD

Postby pspyve » Sat Jun 28, 2025 7:28 am

Hi guys, just wanting to get some ideas on what I am doing wrong. I've connected all the wiring in the right places I think. But what is supposed to happen is when I change the speed of the spindle ( by typing s2500 in the MDI) this should change the voltage at AO1 (on the AXBB-E). However it doesn't. Whatever settings I change in uccnc it always remains the same (1.015v).
I've left the jumper on as it says printed onto the board that on is 10v and off is 5v

Here is a screen shot of the spindle page settings.

I just am wanting to know what settings I need to change to get the AO1 terminal to read voltages between 0 and 10v.
Cheers
Phil
