My experiences with that thing may save you some heartache & confusion: http://softsolder.com/2011/01/06/thing-o-matic-extruder-controller-power-supply-improvement/ http://softsolder.com/2011/01/07/thing-o-matic-extruder-controller-mosfet-supplies/ The MK7 extruder uses a cartridge heater, but I still recommend electrically isolating the thermocouple from the block, as their method of securing the bead to the hot end leaves a bit to be desired. http://softsolder.com/2011/02/06/thing-o-matic-mk5-extruder-protecting-the-thermocouple/ http://softsolder.com/2012/01/07/thing-o-matic-improved-ec-thermistor-connector-orientation/ It is a rather expensive & complex board, given that you'll be using only one thermocouple readout and two MOSFET drivers. It's not obvious that the RS485 interface is as simple as it appears, either, because a common failure seems to involve the Motherboard losing contact with the Extruder Controller. -- Ed http://softsolder.com ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
