a little cleaning


here is my hot end, i thought i would try to clean it today, turned out to be a bit of a chore





i am going to have to get more of this stuff from maker gear, but the pla leaked into it and made it pretty solid on that side



here you can see the difference from where the PLA leaked onto it and where the
heater core was.



it took some effor but i did get it out, i also bent it just a hair, so i think i will order another
 one soon for spare parts.







and today i found the real issue causing the missing steps




you can see here where the motor mount bent, i think it got soft from the heat. for some reason this stepper has always run hot, if i turn down the pot it will start to skip so the power is about righ, but i should think about replacing it soon wish one that should run cooler. but i need to figure out how to get that piece flat again, i am thinking a flat sheet of metal, and using a hot air gun to soften up the PLA so that it would then become flat again.

now i just need to buy a hot air gun next payday.
