the yellow line is the printing tip, and the blue line
is the base where it mounts onto the peek.
i wanted to put the heatsink i had father down the brass, but it was too big and the fins hit the wood mounts. but i think this may be something worth looking into more for me at least, but i am going to see if i cant find a smaller heatsink.
the second dip is where i had a bigger fan blowing on to it, just to see how it would react. it had a harder time heating up and keeping up to it but it was also a fan from a older amd cpu cooler, not that small little guy i had on the heatsink. it dose go to show just how much a poorly aimed fan could affect your printing, maybe even show how much a properly aimed one could also improve it too.
i think i am going to look into ways i can make this process better, i know i dont want to make it too cool, but i think it could help allot if i can get it to stay about 80C to 90C where it meets the peek. with out making the hot end work any harder than it needs too.
i look forward to doing more stuff like this, i find it very interesting.
