so most of the time i print with an sd card however ive been trying to connect to simplify3d through the provided usb cable. however, it doesnt seem to be working. it tells me that another device is connected to serial port com3. now ive gone throught the device manager and the only device connected to any serial port is the printers mightyboard (no other usb devices are connected to the laptop). so the mightyboard is detected but for some reason the printer will not connect. i had the same problem in repg.

if anyone can give me some guidance it would be much appreciated.
