orion hot end wont heat

[Navkram]

just happened during a print, working just fine I walk away and come back later notice that it stopped extruding plastic, get looking and the filiment pushed out the side of the ez struder, thought well there is the problem, cleared all that and re threaded the filament, went to reprint and waited and waited and the hot end will not get over 209??? any thought on where to start.

Make sure that the Thermistor is where it is supposed to be. Ensure that it has not pulled out of its hole, AT ALL.
Inspect the resistors to see if one may have cracked. If you used connectors on the thermistor and resistors you can disconnect them and measure them
with the multimeter. The thermistor should read 100K ohms at room temperature. The resistors at the connector should read approximately 3.4 ohms.

I just had the same thing happen to me . No sure where to start. The connectors are crimped together . They seam to be loose in the two out side holes an also the thermocouple is loose . How do you reseat them .I think this is my problem. I was thinking of replacing the head with the E3D v6 hot end so i can print nylon, any thoughts .The printer only has 7 days of printing on it . Thanks again ..

I only had 3.5 days of printing when my resistors kicked the bucket and I had to replace them as my hotend wouldn't go above 215-218 or keep a constant temperature.
I went with a 40W heat cartridge and while I had the hotend off of the printer I went with a screw in thermistor.

It served me well for about 6days of print time until I installed an E3D V6.

Use a heater cartridge and screw in thermistor, much better than the stock setup.

or better yet install a E3D v6 and be done with it !

ok i bit the bullet ordered the E3D v6 head this am .A Nice upgrade so I can print nylon . I understand you have to change the arduino code to get the max temp ?. Any suggestions would be Great , just waiting for the new AWESOME E3d and some different size extra nozzles ...wooot

[Fester]

OK I need help . i Have been looking all over on how I hook my computer up to arduino to configure for the new 3 E3D v6 hot end ?

There is a max temp setting in firmware you need to find out which thermistor table you are using, usually it is one and the table needs changed to number 8.
Then find a statement like this one: #define GENERIC_THERM1_MAX_TEMP 300 to change the Max Temp to 300C.
These settings are in configuration.h and after changing them you must upload the firmware back to the Rambo with Arduino.

and then, at the bottom of the config h file is a setting that limits the maximum temperature you can set the temperature from the control panel. I think it is currently set at 240.

When you get a chance would you be kind enough to list that setting? I have not run into it yet because I do not normally exceed 240c.

Thanks so much your help . Any one use kisslicer ? what settings do i need to change here .I cant seam to find nozzle size any where .
This may be what he is talking about .

I love this solution.
How did you deal with the mounting hardware incompatibilities?
