First error hurdle

Hi all,

Just tried to get the electronics working and have this error;

start
echo: External Reset
Marlin: 1.0.0 RC2
echo: Last Updated: Dec 14 2012 14:20:23 | Author: nophead

: Extruder switched off. MINTEMP triggered !
Errorrinter stopped due to errors. Fix the error and use M999 to restart!. (Temperature is reset. Set it before restarting)
Resend:1
ok

Not sure what to do here. The electronics are RAMPS 1.4 and the extruder stepper is plugged in but not the thermistor or hot-end. Will that cause this error? Guess I should connect them and find out.

You need to plug in the thermosistors or disable the temp/ thermosistor setting in in marlin fimware . .someone correct me but on the top of my head change to zero "0" value . .this is good if your are testing motor functions . .or calibrating your x,y,z axis

I got that error a couple of times.

First time, my thermistor (the one that reads the temperature) wasn't connected properly.

The second time was because I had blown a few resistors, so I tried a suggestion of Vik's and built my own resistor out of nichrome wire wound around the heater block and imbedded in furnace cement. This time it was intermittent and I finally figured out htat the furnace cement hadn't dried 100%. After a few faulty goes, it heated up enough to dry completely and I haven't had a problem for a couple of months.

Alizier21 - any idea where in the code that switch is? I didn't see anything in either the configuration.h or the configuration_adv.h (could be a "man" look of course!)

Otherwise I'll wire up the head tomorrow - which needs to be done anyway.

Cheers
Colin

loading marlin to ramps 1.4<< not sure how to upload video so it will show here




The link is a video loading marlin onto ramps 1.4 . .

Just change the "1" to a "0" value for the hot end and the bed . .

Hope it helps . .

Its in config.h BTW . .

Just check marlin . . I>>change to "0" to disable ( not used)n config.h tab, line 78 . .

Sumptin like this:

#define TEMP_SENSOR_0 1>>> change to "0"
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 1>>>change to "0"

Note that you have to change this back to whatever your thermosistor value is
before using your hot end and heat bed . .

Excellent, thanks, that makes perfect sense now I look at it.
