Problem with Marlin and No hotend

Hey,

I'm new to 3d printer setup. I'm building a paste extruder 3D printer where no hotend is needed, neither the head, nor the bed need the temperature control for now. I'm using Marlin firmware on Arduino Mega with Ramps board to operate my 3d printer. Marlin won't compile if all the thermistors are set to "not used = 0".

Does anyone have an idea how to overcome this problem?

Thanks!

Just connect a thermistor, you don't have to use the temperature control in the slicer, so you can compile the code and just ignore the temperature reading. That would be the simplest thing to do. If you want to do it in the code, find out at what line the error is reported. You can try commenting out the #ifndef and see if it compiles.

... for using Marlin and Marlin4Due without extruder I've jumpered a resistor across the thermistor pins

yea a 100k resitor over the thermister pins is the easyest
