Hi guys I had a problem with the r271 blowing (yep cleaning the tip with power) on and so as per the fine information on this forum I did the repair as suggested. All went well and it started a demo print via the built in sample and it laid down the first layers then started cooling down (the extruder). So off with the cover and oops the inline fuse I added was popped so replaced it this morning, turned on the printer went to change filament (not cartridge )and it started to heat and then pop it blew that fuse. I've checked my soldering and nothing else was affected. Any idea what to check for? Until the extruder stopped I have had about 350hrs on it without any trouble.
