-10V to 10v circuit

[EddyCurrent]

Sorry I can't be much help here, it's something I've not looked into with Mach3

using -10v to 10v is normally carried out with a joystick control and a VFD, -10v is the reverse direction whereas +10v is forward direction.



To generate the -10v to 10v you could use a simple potential divider across a 20v supply with the centre tap connected to zero or you
could search for a better circuit on Google for example using the search term "Dual rail power supply"

There's some info here that might help.
