ok

another question, when you tell the machine to move, as you said it does not physically, but do the values on the DROs on teh mach3 screen change?

also do you have an oscilloscope?

when I press the arrow keys or turn the wheel on the pendent, yes the values do change, but no movement.

if i type code in, nothing happens, except for m3, spindle will turn on and off and i can change the rpm

no scope

ok what about a voltmeter/multimeter?

i try to find a way to get you to test if pulses are actually coming out of the control card to the stepper drivers...

maybe someone on this forum knows a way to measure with simpler tools...

Well you should be able to measure around 5v and 0V on the DIR pins depending on which way the axis is moving. So X axis DIR pin will be high in one direction and low in the other.

THe pulse pins i imagine will be 0 or 5V when not moving then on a multi meter, it will effectively average the pulse levels, so it might be ~ 2.5V when moving. Or it might dance around when moving, it could depend on the meter exactly, but the point is you should see a difference in measurement between stopped and moving.

If that is a go then next step i would measure the power supply to the stepper drivers them selves. Probably it is 24 V DC on this machine, but look for the power supply it will say on it i would bet.

yes it does

if i look at the screenshot of this reply
step pin is 1 for all axis. that cannot be ok.

Manual says it it 2,4,6,8     X,Y,Z,A
anything is possible, just try it.
if you find some mistakes, in my bad bavarian english,they are yours.

i dont think it matters with this card what the pin settings are for each axis bc they have dedicated pins on the card. see page 3

worth trying though if nothing else is working :)

fair,  i used to have this card though, i could be wrong but i remember not having to config the pins. it could be a problem though if you set them all to the same pin, who knows.
