On a functional 4 axis rig, the UC300-USB was removed and replaced by a UC300-ETH, on a UC300-5LPT board.
UC300 plugin version v1.020, Mach 3 version X.066, running on Win 7, 64 bits.
One C11G BoB from Arturo (CNC4PC) connected on physical port 2 of UC300-5LPT. All pins assigned to "port 2" in Mach3 menu Config / PortPins: works flawlessly.
Connected second C11G on physical port 3 of UC300-5LPT, and assigned pins to "port 3" accordingly in Mach 3 No success.
One Wizard (thank you again Gerry) in this forum and the manufacturer of the UC300 board could not help.
The second C11G card is brand new, and wired in a similar way as the first one.
Sending a signal that makes its way through "port 2" in Mach 3 to "port 3" and connecting the original working C11G card to the appropriate physical port 3 on the LPT5 board fails. This seems to indicate that port 3 on the LPT cannot be addressed.
The alternative test, taking one pin along the "port 2" route and assigning it to "port 3" in Mach 3, makes this pin unavailable. Thus Mach 3 makes a difference between "port 2" and "port 3", regardless of the actual route beyond.
How can one port only on the LPT5 be defective ? (cable tested to be OK)
Has anyone another idea ?
Enjoy your week, Philippe
PS: the monitoring window of the UC300 plugin reflects the exact observations made trough the whole controls chain.
