Tried the reflash, timeout,

Recieved the printer in Sept 2014, up to this point happy with product, but …

When the controller is just connected to the USB 2 LEDs are on (red & green). When appling 15V they go out and a green LRD flashes and goes out. All as it should be.

Several reasons for Repetier not to connect.

  1. Drivers not installed or incorrect drivers. Installing V0.95 should install drivers but not the latest. This forum has plenty of info on the correct and newest drivers.

  2. The USB port is not the correct 1 with the drivers for the controller.

  3. When I had this problem it was only fixed by getting an exchange board from VellemanUSA.
