I’m building a 3D printer from your kit, and I have finished the all the hardware and wiring. I’m trying to connect the printer to my laptop, drivers are loaded, Repetier installed, but the port is showing me Code 52 error, and so I cannot connect over in Repetier.
In Device Manager, Windows showed me this message in the port’s Properties: “Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)”
Repetier showed me this message: “The connection with the following error: The port ‘COM3’ does not exist… Make sure your printer is connected, enabled and connection data is set correct. Open printer settings?”
Both LEDs on the board is on, one red, one yellow.
My Windows is Windows 7 Professional 64-bit, the driver I installed is VCP 2.12.06 from FTDI, Repetier version is K8200 Repetier Host v0.95F.
Please help me, and let me know of any suggestion at all. I’m doing this project for a class. Thank you!
