Makerbot #453 : When it go bad ....

First extrusion !!!
But after a minute the feed stoped....
The wheel was not enough pushing on the ABS.
Result : ABS burned in the head. Now it's time to remove the head...not realy a easy part. The Tape was burn around the Nichrome wire making it realy hard to remove.
When completed, Time to heat the barrel with the torch to get the ABS out.
