Thanks Jazz,

Is there a preferred circuit or supplier of parts for a suitable linear supply?
Need 48v at up to 10A.

Keep the BOB on the SMPS?

The radio interference has been nagging me since i got the plasma going - same drives, motors and PSU again, no help at all from CNC4YOU of course.

I always use shielded motor cables, grounded at the drive end, and even used shielded wire for the step/dir signals on the plasma.

No objections to building a psu but cant risk over-volting the drives by building it wrong, they are ok up to 50v

Thanks
