**SOLVED** Cell Phone Causing Interference?

I haven't had a chance to triple check.. I just built this Rostock and need to finish printing the second fan mount..
I decided to start using the SD card to print, twice the printer has stopped printing with no error message. Both times happened when I walked near it with my cell phone in my hand. I will try to validate this after I get these fans installed.
If anyone is having similar issues with their prints just stopping and no error.. chime in.

It isn't impossible for it to be the cell phone, just unlikely. Still, I remember I've had plenty of speakers pick up cell phone interference right before a call came in. I If it is the cell phone causing the issue, I believe it would not be the only factor involved, just the one that is the trigger. So there are likely more things not quite right to let it happen.
If you want to test it, you're going to have to try various things such as removing the ribbons to the panel from the rambo, checking your voltages on the power to the board (short of using an o-scope, if a multimeter is picking up any AC voltages or an unsteady DC voltage they would signify this as a possible problem). Another thing is checking what else is on that outlet and maybe even breaker circuit if you have something that might be causing some noisy power. That's all I can think of off the top of my head for simple to check issues.

Can confirm it was not cell phone interference as it has happened without the cell phone present and I have completed prints with the cell phone. Seems to be a lose connection with the USB was causing my files not to upload all the gcode to my SD card. Thanks for the comment. I knew I was probably over thinking the situation but it seemed to have failed both times when I had gotten updates on my phone. Just a coincidence though.

Are you using the original SD card that came with the LCD?
If so you should consider upgrading the SD card to a faster card (class 10)
Do not purchase Kingston. It is documented that the original SD card will cause
problems like you describe.

depends how old the machine is, we have been supplying with sandisk cards now for a while to eliminate that problem.. the main problem ones were the white and blue label "high speed" unbranded cards

Thanks for the update Guanu, I was not aware that you changed the cards to Sandisk.
