Hi,

I'm converting a Sherline lathe to CNC and want to have spindle speed control. I had this working when using a Gecko G540 pins 7,8,9.

I am now using 2 seperate Gecko drivers with a CNC4PC C25XP bob.

Does anyone know if there is a VFD pin out on the C25XP that functions the same as pin 8 on the G540?

When I MDI m3 s2000, I get around 8.6v from the 0-10v pins on the C25XP. If i MDI another speed , pins stay the same. Is that expected?

I'm going to check over the ESS settings, too.
