Hi,
I'm new to the forum but not new to automation. I purchased the UC300eth-5lpt to play with on one of my CNC machines. I use the UC100 USB dongle on two of my cnc's.
I did all of the install as per the manual and got the com running with no trouble. I did the firmware update at initial start up with Mach3 and went on line.
I set all of the pins and ports to the new Port-2 and 3 to suite my machine. This is where the fun begins. Only output pin 5 will toggle 0-5vdc when the X axis jog key (button) is activated. But, even though I want X motion, the output for the Y axis direction changes state. If I move pin 5 (in ports-pins) to a different axis, pin 5 is the only axis that works.
I changed from LPT-2 to LPT-3 and got the exact same result. I did the install on one of my other CNC computers and got the same result.
I removed the UC300eth and did a close examination of the board. Using my 20X eye loop. I looked at all of the traces and pins. I found solder beads and smears on the board and several of the pins on the main LSI chip had excessive flux between the pins. I cleaned the flux and solder off the board and tested it again, only to have the same results. I am having a hard time making my self believe it is the hardware because both LPT ports react exactly the same.
If anyone has some input on this please let me know. The UC300eth is just a toy for my new CNC I just made from a Grizzly G0705 Mill/Drill.
Here's a link to the Youtube video I made of it.
