E3D v6 maxtemp issues
July 18, 2015 07:52PM
Hi all, just got my E3D v6 in today, so I put it all together and got it all connected to my printer. However every time I turn my printer on I get ERROR MAXTEMP on my LCD. and it shows 739/0C for my extruder. I checked with my multimeter on the pin connector that goes into the ramps and observed 1.6 OHMs resistance. I dont know what it is supposed to be but a non 0 value to me would indicate it isn't shorted? Or is it supposed to be more like 100kohm like it says in the config file? Otherwise is my thermistor I got bad? I changed my Marlin configuration to :

//// Temperature sensor settings:
// -2 is thermocouple with MAX6675 (only for sensor 0)
// -1 is thermocouple with AD595
// 0 is not used
// 1 is 100k thermistor - best choice for EPCOS 100k (4.7k pullup)
// 2 is 200k thermistor - ATC Semitec 204GT-2 (4.7k pullup)
// 3 is mendel-parts thermistor (4.7k pullup)
// 4 is 10k thermistor !! do not use it for a hotend. It gives bad resolution at high temp. !!
// 5 is 100K thermistor - ATC Semitec 104GT-2 (Used in ParCan) (4.7k pullup)
// 6 is 100k EPCOS - Not as accurate as table 1 (created using a fluke thermocouple) (4.7k pullup)
// 7 is 100k Honeywell thermistor 135-104LAG-J01 (4.7k pullup)
// 8 is 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup)
// 9 is 100k GE Sensing AL03006-58.2K-97-G1 (4.7k pullup)
// 10 is 100k RS thermistor 198-961 (4.7k pullup)
//
//    1k ohm pullup tables - This is not normal, you would have to have changed out your 4.7k for 1k 
//                          (but gives greater accuracy and more stable PID)
// 51 is 100k thermistor - EPCOS (1k pullup)
// 52 is 200k thermistor - ATC Semitec 204GT-2 (1k pullup)
// 55 is 100k thermistor - ATC Semitec 104GT-2 (Used in ParCan) (1k pullup)

#define TEMP_SENSOR_0 5
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 6

and reuploaded several times. I am out of ideas and have no idea what is wrong??

I couldn't find a way to remove the post, but it was a short. I looked into it more and the torque from the screw that hold it in pulled the insulator up the leads a bit and they were shorting on the block. a 100kohm resistor shouldnt have a reading of 1.6 ohms im a dummy.
