I'm in the middle of a CNC router build, with a Sherline spindle and Gecko G540.
I see that the 540 has "0V to +10V opto-isolated analog output intended for use with VFD drives."
A year ago, when trying to control spindle speed on my Sherline mill with another brand of spindle control, I burned out my spindle controller and the 0-10v board because I didn't use an isolated power supply, and
Now, I've got it working on my Sherline lathe, and want speed control on the router as well. Will the Gecko handle this?
