Mach 3 isn't swinging the voltage during jog direction change. After reading through other people's posts and trying what they did, I still haven't solved the problem...any ideas? Here is what I've tried so far.
With my BIOS set to "Normal" for the Parallel Port:
High Voltage with the Port Monitor is 3.3V
Low Voltage is 0V
With my BIOS set to "EPP" or "EPP+ECP" for the Parallel Port:
High Voltage is 4.5V
Low Voltage is 4.0V
Either of these setups Mach 3 does not change the pin voltage from High Voltage to Low Voltage after jog direction change; it just stays at the high voltage. I am reading the voltage straight out of the motherboard port. I have an option for "Enable Legacy PnP detection" in my device manager for the parallel port and I've tried that, but it didn't seem to do anything.
Yes, I have:
Enabled Port #1 and verified Hex Address shown is the same as in Device Manager
Enabled X->Z axis
Set Step Pin# to 0 for all three axises (just for verifying port)
Set Dir Pins to 2->4 for X, Y, and Z
Set Dir and Step Low Active
Set Dir and Step Port as #1
