Hey folks,

Ever since I've built my MendelMax, plugging/unplugging 120V tools interferes with the communication between my laptop and the printer (which is over US. I've tried reducing the communication rate from 250 kbaud to 102.5 kbaud, but that didn't resolve the issue. The USB cable is quite long and I'm not sure how good the shielding is. Could a lack of shielding of the USB cable be an issue? The power supply is plugged into a surge protector, if that matters.

Thanks for any suggestions, as this is a huge annoyance.

On a related note, if the prints stops due to communication error, is there an easy way to resume the print in Repetier Host?

Fortunately, it appears that the problem was solved with a different USB cable .

Sounds like a grounding issue... the other usb must have a better ground. Check to see if your power supply ground carries over to your printer.
