Greetings all,
I am a newbie building my first CNC project which is to be a 10'x9'x5' hotwire foam cutter, I have all my electronics situated in an enclosure and my steppers connected for testing. In trying to text my computer's parallel port, I opened MACH3, set the screen to Program/run mode, selected "config">ports and pins>
Port Setup is "port #1 enabled
Port Address is 0x378
Motor Output > x,y, and z axes are set to 2,, 3, and 4 respectively
Input signals > "e stop" is enabled and set to pin number "0"
I clicked apply, OK
Went back to the program run screen
clicked "reset" so that it was not blinking
stuck a paper clip in the second hole at the bottom, on the "wide side" of the computer's parallel port.
but....I'm reading 4.44v no matter which arrow key I press
What am I doing wrong?
Thanks
Here are a couple of shots of my controller...
The box was an outdoor solar-power enclosure.
