Re: [CAD_CAM_EDM_DRO] Jumper innovation?

Hi Peter,

Try to find a miniature header connector. These headers on the driver
module are smaller then the old .025 x .1 headers (I don't know what
they call the new ones!). Otherwise it would be easy to find a ribbon
cable with the appropriate connector.

On another thought, are you putting the jumpers on upside down? Look
closely at the jumper, they only go on one way (I think). Look at some
you haven't touched, that might give you a hint.

They ARE tiny!

I'm thinking I want to select the current resistors with a switch. This
way, I can use the driver/power supply to drive different systems
conveniently. I had thought of putting the resistors in the motor
cable's connector. That way the motor can "select" the current it
wants.
