Hi

The title is a bit of a mouth full but I'll explain.

I've converted an Optimum MH28V mill to CNC and it uses a KBIC copy speed controller for the spindle.

I read somewhere that using the CNC4PC C6 card would allow me to control the KBIC speed and direction via 0-10V output.

I've got a voltage output from the C6 card but it is only 0-2.9V

Does anyone have any experience in this area and any ideas as to how to get the output voltage higher please.

Cheers
Phil
