Help there, One of the fans of my Ultimaker 2 does not work anymore. Unfortunately, the spare is not available at my usual shop (Makershop in France) and will request a few days to be delivered. Is there a possibility to buy a PC-fan and mount it ? Does someone has the specification of a compatible fan ? Is there any drawback to use such a replacement ? Thanks, Jean-Philippe

I had a strange behaviour of my Ultimaker 2 extended yesterday : the filament was going backward ! The feeder was confusing up and down, back and forth. Impossible to move filament except with the advanced settings. The answer was given to me by Sander : I did a wrong firmware update, using the UM2+Ext firmware instead of the UM2 Ext. So, for those like me that a dumb enough to download the wrong driver and before your take a screwdriver to unmounted the feeder, or before crying on the shoulder of the support : check the firmware !!! Yours, John Doe (so ashamed!) NB : thanks for Sander vG. who did promptly solve my problem. Not only this company makes excellent products but they also deliver great services. Who wants more ?
