i eventually re flashed the extruder board. this seems to have cleared things up. i dont know why as the TechZone boards are meant to work out of the box and for the most part did. just waiting for some PLA and then it's time to print. WAAHHOOOOby dobo - General Mendel Topics
it is defiantly close to a short. i couldn't get a noticeable difference when hot but i am using a cheap old DMM. i checked all my wiring for continuity and they all seem to be ok. dose the the thermocouple being a short mean that is defective or is that how it is meant to be?by dobo - General Mendel Topics
i dont seem to be getting any voltage drop across the thermocouple. so i assume that the thermocouple is dead. is there any way of confirming this?by dobo - General Mendel Topics
hi all, first post here. i have just completed the mechanical build of my techzone LC mendle, and started hooking up my electronics. i have all the boards talking to each other and all the stepper motors moving using repsnapper. i also have the hotend heating on demand through the AD board. however the thermocouple is not reading properly. i am getting either 0 or 2000 degrees in repsnapper. theby dobo - General Mendel Topics
