Cannot define heatbed sensor

Hey peeps,

I'm running Marlin 2 on Ramps 1.4 board, using the Arduino IDE. Everything is working perfectly and Marlin is compiling and flashing to the Arduino just fine, until I change the #define temp_sensor_heatbed 0 to #define temp_sensor_heatbed 1. I've tried changing the 0 value to all sorts of other values (the bed thermistor is a generic 100KOhms NTC), but no matter what I change it to, it always fails to compile. If I change it back to 0, everything is fine and dandy once again.

The error messages are as follows:

Any ideas what's going on? and how I can fix it?

Thanks in advance

#define TEMP_SENSOR_BED 1

works as expected


temp_sensor_heatbed is not valid.

you cannot randomly change defines or the case of the defines, the code must be updated to match

You would need to upload your configs for closer examination

Cool, I've attached the files

Sorry I was just typing it out in the post, in the config I havn't changed the case, just the value that denotes which thermistor I'm using. It works fine when defined as '0' but not as anything else, like '1'

#define BED_MINTEMP

this needs a value after it

Thank you so much!

Problem solved! - much appreciated @Dust
