Short list of what I have seen/ found thus far,
I am using Mach 3 software on an XP computer system. I have downloaded a program to verify the software is putting signals out through the parallel port.
What I have found so far,
1 of the 3 motors does not "lock" once power is applied. It becomes a little bit harder to turn with the power on but I am still able to turn it with two fingers.
I have the EN port wired directly to the 5VDC input.
Each motor is wired per the schematics listed on the webpage where I purchased the drivers under the KL-6050 driver page.
The Emergency Stop has been wired also and the software does recognize changes I make by pushing or resetting the E-Stop.
So far I have not been able to get any sort of movement out of any of the motors. I have checked the out-puts to the driver card and with an o-scope probe not grounded I can see pulses (maybe 5mV) as I try to move an axis, once I ground the probe I am not able to see any pulses.
According to Parmon I am only seeing outputs change when I do a negative movement. I should be able to move X & Y with the key board arrows or the manual jog screen. IE.. I push the up arrow the #2 pin goes high, I then when I push the down arrow #3 pin goes high but #2 pin also stays high.
