Marlin Cold Extrude

So I am trying to use cold extrude to operate a motor on a Sanguino using Pronterface due to x/y/z axis all being used. To achieve this I have tried:

• Commenting out #define PREVENT_COLD_EXTRUDE in Configuration.h
• Commenting out the #ifdef of case 302 in Marlin_main.cpp

The printer I am working with has no temperature sensor, so just removing the section of code that disables the cold extrude would be preferable, however if there is a way to dodgy it up i.e. set minimum temperature to 0 Kelvin or something would be just fine too.

newer marlins comes with fake thermistor options that always just read what ever temp they are set to


* 998 : Dummy Table that ALWAYS reads 25°C or the temperature defined below.
* 999 : Dummy Table that ALWAYS reads 100°C or the temperature defined below.

// Dummy thermistor constant temperature readings, for use with 998 and 999
#define DUMMY_THERMISTOR_998_VALUE 25
#define DUMMY_THERMISTOR_999_VALUE 100

so all you need to do is set #define TEMP_SENSOR_0 999

Unfortunately I am using an older version and that didn't work, something like TEMPTABLE_999 not being declared. I will attempt on the newest version of Marlin, however that involves reconfiguring.
