Ramps 1.4 : Losing COM connection during prints: HELP!

Hey Reprappers,

While making my 2nd Ord bot, using Ramps 1.4, I have encountered an issue:

"The printer seems to freeze and lose connection to COM3 about 43 seconds before print ends."

Has anyone encountered this type of an issue? I switched USB cables and USB ports. Though perhaps the connection on the USB port on ramps 1.4 was broken. Not sure through.

Please advise.

Did you switch to a heavy, shielded USB cable and make sure to route it as far away from the power cables as you can? A shielded cable with ferrite cores at both ends solved all of my strange little communication issues. Also, have you tried changing your baud rate? If you're at 250,000, try 125,000.
