Hello all reprapers! I'm currently working on a project where I need to control the temperature of a metal block using a 40w cartridge heater and 100k thermistor. at the moment I am using an arduino mega, a ramps board and a smart discount controller. This is OK in the fact that the PID in marlin works so well but I have far too much kit going on and need to shave it down. I would like to isoby omurray - Firmware - Marlin
