I use my printrboard on a different printer and when I designed the casing for it, I made it so that it supported the cable so that it can’t flex. If you have a Printrbot you might want to design a small bracket that allows the cable to be supported/not move during a print
We are in beta for a revF6… Usb-B 
and push push micro sd. Likely to be the board for the new firmware… Which will not even need usb or sd, oddly enough, if people want to use the “micro host” with LCD touch screen and wifi… An internal (second) micro sd and wifi will handle moving the files without sneakernet or isn’t cable.
Planning on improving the experience/robustness for all choices: those that want the files on sd , those who want to use usb cable, those that want the ease of use of wifi/internet connection/cloud services and those that want to load a file over wifi directly and locally (w/o cloud or internet connection).
Without the micro host (separate board and purchase), the printrboard revF6 will work as it does now. With older boards, the firmware can be loaded and you can add the micro host with its benefits- either to drop the usb or or add wifi w or w/o cloud services.
Lots of ongoing development with hardware, software, firmware and electronics! It takes time and everything must be released at the same time. Getting closer every week.

Brook Drumm I volunteer to be a beta tester. If I cant break it no one can.
There’s an app for that! Not really, but +1 on epoxy. If you have an SD, use it instead of cable (I have a Flahforge Creator pro with SD).

I’ve used a glue gun in the past and glued all around them. Makes it 10 times stronger.
