I have been in the process of rebuilding my CNC router machine. I am now get it rewired. When I shut it down everything was working properly.
The controller is:
UC300ETH-5lpt
Uccnc software.

The problem is that when I power the system on I get nothing out of the UC300 -- no led at all. I have verified there is 5 volts at the board plug in and that the jumper is set for ext 5 volt. From the CNCDrive forum I was told that it means it is not getting the 5 volts.

I need to determine if the problem is the 5lpt motherboard or the controller board. So I am looking for the pin out of the UC300 controller board. I would like to know where to hook up the 5volts directly to the UC300 (rather than via the 5lpt) to see if it will light up.

Thanks for any help.

Are the pins labeled?
According to the document I have, L1 (Left 1) is the 5V input, and L3 and L4 are ground.
The 3 dual rows of pins are Left, Upper (Top), and Right. L,U, and R.

They are not labeled. It is v4.0 if that makes any difference.
Can you tell me where you got the document? I've looked for it without any luck.

Are the L1 L3 and L4 when looking at it from above or from the pin side?
Also is the numbering up then down (like a parallel port numbering ) or side to side?

Thanks

Not sure which is which, as the document I have has no pictures. I got it from Balasz at CNC Drive.
