Duet 3 mini 5+ wifi expansion needed
-
What expansion board would I need to add a thermistor and heater out put to my duet 3 mini 5+ Wifi. I’m currently using all the stock outputs on my rat rig v-core 3 for the heated bed, hot end, and heated chamber with its own thermistor. I would like to tie in directly a inline active filament dryer like the thordson IFD-175 FILAMENT DRYER to have it controlled by the mother board but I need one more hotend output and one more thermistor output to make this work

The smallest option may be a toolboard.

You could either install the toolboard at the toolhead and free up the connections on the mainboard, or use the toolboard as an expansion for just filament dryer.

@ratrig0331 you can connect a thermistor to e of those io_in ports on the Duet 3 Mini that support analog input. You can use a fan output or io_out port to control a SSR or mosfet switch that controls the filament dryer heater.
