No PT100 or K Type on Tool Boards?

[DocTrucker]

Am I right in thinking there is no way of adding a daughter board for KType thermocouples to the current CAN tool board?

@DocTrucker you are correct
The Fly-RRF36 supports PT100's

@jay_s_uk Thanks, I hadn't come across that. That may just do the trick if I can't make use of what's already on this machine. Would have required two tool boards for two; extruders, hotends, thermo couples, and fans. Not to mention a swap to pt100 or pt1000. I was tending towards hardwiring the lot through the cable chain!

@DocTrucker thermocouples are more problematic than thermistors, PT100 or PT1000 sensors, so we advise using them only for very high temperatures. The sort of hot end using very high temperatures would normally use a very hot heated chamber too, so would not be appropriate for a tool board.

PT1000 sensors are widely available now and are less trouble to use than PT100 sensors. So we don't see much use for PT100 sensors going forwards.

@dc42 it is moving towards wiring everything down the cable chain as it does appear a weird mix of add on boards. An extruder breakout board with on board thermocouple amps, and two mosfet switches for the fans. Then daisy chained off this is a board with an arduino beetle for controlling the servo. Makes little sense to me when they have got a high tier processor on the control board. That said they also love tinning hot end and heater bed wires so searching for logic may well be futile!

@DocTrucker what machine is it?
