Your extruder thermistor is the 100k EPCOS part and the bed thermistor the 10k on the Lava, so it should be
Code: Select all
#define TEMP_SENSOR_0 1
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 4

cvoinescu; that is what i have.

I know it works because of the ramps test i ran, the bed LED turned on and the bed heated up so what could be the cause of this not working

The RAMPS Test doesn't look at the thermistors at all!
So It doesn't test them.

These definitions are in Marlin
#define TEMP_SENSOR_0 1
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 4

When Marlin is loaded --- the RAMPS Test code is gone!

Sit tight for a day or two, I am up at micron in Boise fixin a robot. Probably be back home on Friday, I have a lava and ramps 1.4. I will try and figure out what your doing wrong. Probably a marlin setup thing. I think the settings I see here are correct but I have to confirm with my setup.

Remember, after you make the changes to the configuration.h file and save it you need to completely power off the arduino. Unplug the 12 v power supply, unplug the USB cable both. Start arduino, load your marlin.pde file, upload, start pronterface and you should see temp readings for your hot bed. Set the temp and turn on the hot bed. The blue led's will come on and the temp will start creeping up. Mine works ok, I wish it had a bit more power for the 110c abs stuff.

Glad to hear you got it running. We're all figuring this out at the same time.

I believe you can hookup the fan to the D9 outputs. You might have to enable it in marlin, can't remember. Even after you have it setup properly, the fan is not going to run until you send it M codes from pronterface.

M106 S200

Or

M106 S255

Or

M107

Look at this for m codes

Let me know what you do to get it working, I have mine wired directly to 12 v. I would like to have pronterface control over the fan.
