I adjusted the hot end spacing with the paper method and will print fine for a while, my hot end will sometimes clog but It will unclog with the wire method. Then I will do another print but the first layer will be super thin, and the hot end spacing will be off. It seems that my hot end will clog because it ends up to close to the heated bed and the filament cant go any where. when I last pressed the home command, I looked at the hot end and the bed.....the hot end is way lower!!I have noticed black plastic from the bottom of the PEEK and am wondering if the whole barrel/ heater assembly is sliding out of the peek. the highest I've printed at is 200C. Please help!
