Error extruder switched off MAX TEMP !

[jojobuddy13 0]

I am currently making my own 3D printer using a Rambo 1.3 board.

After taking apart an old MakerBot Replicator, I used the part from that printer.

I am using Cura and I plugged everything in powered it up and downloaded all the software I need to.

I pressed print to USB and an error sign came up

"Error Extruder Switched off MAX TEMP ! Reached"

I tried to research this and it said to switch my thermocouple's, which I did, and I still got the errors.

Please Help!!!!!

The UM has a AD595 tiny circuit board on the print head combined with a thermocouple. Is that what you have do you think? You should ask people in the makerbot forums (oh - right - they block this kind of post, :???: ).

Well is there a circuit board to go with the thermocouple? Or is it maybe a thermistor instead? If it's a thermistor measure the resistance at room temperature and at say around boiling temperature and then find out which thermistor in the set of thermistor tables match the part you have.

And please update your country in your "location" settings as advice often depends on country.

If you *do* have the ad595 solution, measure the output voltage of that board - it should be 0V for 0C and 5V for 500C and linear in between (200mv for 20C or room temp).
