i bought an AKZ250 usb card. two steppers and installed Mach3
In works well with motors and limit switches, they are reflected in simulated leds of config tab
i have configured supossedly right the pins, not low active, but the response of the card is incorrect,
            volts in card
output     off    on
   1         0.5   0.8
  2-5       0.5   0.1
I wonder if that correspod to a damaged card, if it is replaceable the corresponding chip in the card or another thing. Do somebody knows how to solve this?

CNCDIY doesn't have any support team answering, it seem they are very smart saving even the salary of the support team.
I complaint about it and instead of trying to solve, they blocked my account.  So if somebody is evaluating to buy this card or equipment, consider their null support and inexistent client care, frequentlly found in oriental companies!!
