I have searched the site to find a similar problem with all the posts concerning this, they are all incomplete, with no real answer..
I have followed the directions from the cnc4pc site. it is an old board but I bought new and just now getting to use it..
pp/millopp/checked the box set to step/dir
pp/motoroutputs/checked spindle set to pin 14 for both pins port 1 (vol/acc I have tried from 500 to 2000 in 500 increments and have the step/dir pulse set to 5)
I did try setting only one pin for step/dir to 14 leaving 0 in the other, and all 4 combos with the dir/low. well back n fourth for 3 hours with different setting here
I have tried almost ever config with dirlow/lowactive
I can get the pin14 on the 5vdc side to work, but not the 0-10vdc?

I have all 3 axis working, plus flood/mist
the charge pump on pin 17/jumped properly(x,y,z will not work with this setting incorrect?)
I am using a baldor smartmotor as my spindle(which at this point doesn't matter because I can't get the required 0-10vdc. on the out of the EPOT)
I have tried many different setting in the pulley setup.....
Anybody got any ideas?
BTW this is not a mill/lathe/router/plasma/laser it is a 3 axis machine with a spindle which has no meaning really just gonna answer now..lol...
HELP PLEASE, I want to final test this soon.... I can run the spindle manually but I have already tested that way...
