Ok, great. Time for some head cleaning. I'll certainly add that to my maintenance list.

I've been using my own technique to remove dust and I guess it's working because I've had no jams. I take a TecPad and cut a 1" strip. I wrap that around the filament a few times and then as tightly as I can secure it with some scotch tape, but not before folding the very end over to create a "courtesy tab" we call it in the photography business. That way you can just lift that small end that hasn't stuck down and pull the tape off if you want to remove it without having to slice on it. I put two of these little wraps on the filament, one in front of the other. When I pull that filament off of the machine, it travels in place on the filament to my moisture-free bucket for the next use. Every so often I replace the wraps but with two of them I'm pretty sure the first one has snagged the debris but for sure the 2nd one collects it. So far so good but I may look into a more elaborate one like what's in your link.

I am glad to see an accepted method to clean the head though. Very nice. One thing that newer users than me might need to consider though is if you have Ramps and Marlin, you may need to go in and raise the safety temperature of your head or the machine will just shut off due to excessive temperature readings. I think the default Max Temp is well below 270C.

Thanks
