RE: [CAD_CAM_EDM_DRO] 48V 10A! Mauch 2A board?

The biggest problem with the higher voltages is the heating of the L298
is difficult to manage. I have tested the 2A drivers to about 40V but
have extra large heatsinks on the L298's and you must have a good volume
of air blowing across the heatsinks.

"I've been having random intermittent dropouts (where an axis will stall
and
whine instead of moving) on my Sherline (Mauch 2A board, 24V 8A
switching
supply) and remember reading that switching supplies will sometimes not
have a tolerance for the spiky voltages produced by a chopper driver. I
do
have a 4700ufd 50V cap across the output terminals of the supply."
