UC300ETH HELP
« on: March 02, 2019, 01:57:53 PM »
I am using an uc300eth plugged into a cnc4pc c76 card.If I launch Mach4 with card powered Mach will not load If I launch Mach then power card Mach seems to work .Cheching the out port LEDs they will stay lit after the keys are released.I do not have any motors connected .I have assigned pins and ports in Mach and was trying to verify I have the ports assigned correctly when I noticed the leds getting stuck .Was wondering if this is normal?

Hi,
if the current MDI move or jog move requires that the Dir output be high (LED on) to go in the required direction
it will stay on at the end of the move. In fact it will stay on until there is a subsequent move that requires the axis go the
other way. The Step LED should however blink very rapidly, so fast that it appears just somewhat dimmer than full intensity
while the move is in progress. Once the move is complete the LED should extinguish and not relight until another move
is made.
