Re: [CAD_CAM_EDM_DRO] Re: Delagrange stepper driver board

It says that now. They also claim 50 volts, or did then. 12 volts and 6 amps fried it. The hexfets arent or weren't even on a heatsink. A 10 amp rating should mean about a 12 amp failure conservatively. Would anyone expect to get 50 volts and 12 amps through a hexfet out in mid air and nothing to sink on?

my Bridgeport as the seller claims it is a 10 amp stepper driver
board. The 10 amps refers to the relays on the board for the spindle
and coolant control. The actual drives, I could never get a straight
answer to their amperage rating (after I bought it).


The web site is VERY clear. and I quote


"It is built to handle up to 10 amps per phase per motor"

I didn't see anything in my very brief look about the voltages.

But, I am sold on microstepping. HobbyCNC has a kit that is pretty
low in price if it is in the range you need. Next step up from there
(in my opnion) is a Gecko.
