I recently got 3 Printrboard clones (GEEE Tech) on ebay. Only $60 ea with free shipping from China. (I still don't see how that works.) The boards looked good except they weren't cleaned well - a uniform resin film over them. I figure their cleaning vat solvent was long over due for changing. Not being hugely familiar with Arduino stuff (I had managed to wrestle a Brainwave board into submission once), and with the very confusing verbiage on the geeetech.com wiki page, I had a hell of a time sorting out what type of bootloader was on the thing and whether it was actually working or not. After stumbling around for a few hours, I finally got Marlin built and downloaded.
So I figured I'd go ahead and flash the other two boards. For the life of me, I couldn't get either board to enter bootloader mode like I finally had managed with the first board. At this point, it dawned on me that maybe the reset button was faulty. But on both boards? Then I remembered the flux residue. Sure enough, neither board's buttons were working, and as I though back, I realized that the first board's button wasn't actually working to begin with either. I had to take apart the reset buttons and clean them out with a toothpick. Now everything's working. I guess you get what you pay for...
Does anyone have a suggestion for the least offensive solvent I can use to clean the rest of the boards? Unfortunately, the flux residue is not water soluble.
