Repetier firmware excluding temperature sensors.
Repetier firmware on hardware without hotend and without hot.
I can not understand how to exclude the temperature sensors.
If you have no hotend you also need no extruder and can set NUM_EXTRUDER to 0. If you have some special thing using still extruder, you can use temp. sensor type 0 (Fake sensor). in 0.92.3 firmware. Just remember to never set temperatures in gcode then.
