I'm finishing retrofitting and Zund table plotter with new steppers, Windows 7, a Gecko G540, UCCNC, a UC100 controller, 2017 Screenset. My issue is when I start UCCNC everything works (motors run and I can execute gcode) as it should for a few minutes or less and then I get the message that UCCNC has lost connection. I shut down UCCNC and try to restart but of course with a lost connection, it come up in Demo mode. I have to then re-start the computer (though it doesn't want to finish the shutdown) and load UCCNC again, only to repeat the cycle in a short period of time. Not sure where to start. Windows, my UCCNC setup, the UC100? Everything is new except the windows 7 computer and the table.
I bought most of the hardware from Automation Technology, so I'm hoping there are no issues with the UC100 being a fake. I've had some other issues with the power supply fan and shipping damage but that's probably for another thread.
Any thoughts?
