Ok... the UC100 arrived. I followed the instructions for the automatic installer. I let it install the drivers, plugged in the UC100 to the computer via the USB, rebooted the computer, started Mach3 and let it do it's thing.
Now I'm having an issue where when I hit the reset button on the screen the following happens briefly:
On the G540
1 - The red "fault" light goes off.
2- The green "power" light turns on.
When looking at the UC100 In/Out Monitor:
3- The red "Estop" indicator turns off (blank).
4- The blank "idle" indicator turns red.
5- The Pin State of "15. Inp ." (yellow) goes blank.
6- The Pin State of "16. Out." (blank) flashes red.
7- The motors go active (not moving).
8- The Blue and Green LEDs on the UC100 are lit constantly, the Blue flashes off when the Reset button is pressed.
The above lasts about 1/2 seconds.
Then it goes back to the previous state.
Motors inactive, "Fault" lit red,"15. Inp." lit yellow, "Estop" lit red and "Reset" button flashing indicating "Emergency Mode" on the screen.
When I watch via the diagnostics page, I see none of the indicators lit until I push "Reset". When I do that, the "Emergency" indicator flashes briefly.
All of the limit and home switches are showing the proper indications on the diagnostics page.
I had outputs 3, 5 and 7 indicating red in the UC100 Monitor until I checked "Dir LowActive" for X, Y and Z axis in "Motor Outputs". With those checked, those indicators are blank. Even with these unchecked, the machine still does the same thing, except that the indicators for Outputs 3, 5 and 7 are lit red.
I do not see the change of indicator expected when changing the Estop switch position. There is no indication on the diagnostic page or the UC100 monitor.
I was using the older XP based computer for all of the above testing. I decided to try a newer 64 bit Win7 machine. I loaded Mach3 and repeated the driver installation procedure on the new computer only to get the exact same results.
It seems that no combination of Active Hi/Low for any of the inputs including the Estop will get this thing to stay active. I didn't have this problem before the UC100. Without that, inputs 3 and 4 were not making it to Mach3. It would go active, it just didn't respond to inputs 3 or 4. I have tried this with the Max Step Rate set to 100kHz and 50 kHz. Also just for giggles, I tried Dereference axis on Estop both ways, no difference though.
So, no joy as of yet.
