Solved Programs think hot end is heated when it isn't

Should I buy a new hotend? That would replace the thermistor entirely, right?
Also, how would I identify bad ramps?

 

I got a multimeter...
And I have no idea what these readings mean or if I am testing correctly. I placed both positive and negative lead on the thermistor and at first the reading was 85 or 70, and then quickly dropped to 10, and continually dwindled down to around 0.2-0.1 and hovered around there. Pictures are hopefully acceptable...Just wanted to upload one my wife took while the resistance looked like 2.4, but it still dropped to 0.1-0.2.

 

So I pulled out the wires from the coppery piece and have started putting the test leads against the appropriately colored wire at the end. Once I do this I am getting readings in the 290's and they are consistently around there. Is this the appropriate way to test the thermistor?

 

Oddly enough when I turn the printer on and do the same thing I can't get anything other than 0.0

 

I read this article which seems to indicate the Arduino board (Is the mega 2560 considered the RAMPS, or is the board on top of the mega 2560 considered the RAMPS?). http://kevinrye.net/index_files/replacing_the_arduino_and_thermistor_in_my_robo3dr1.php
Anyways, I found some cheaper parts on amazon and when I have some money I will be ordering some new thermistors along with some new wires, as well as the two boards and trying this out.
Please still let me know if I used the multimeter correctly as I wills till need that knowledge

 

I bought this one refurbished a couple of years ago and it has been nothing but problems since. It seems to have the defining characteristics of the r1+, but I cannot say for certain.
The bead came out because I was trying to pull the entire thing out and could not get any purchase on the brass tubing. That may be my bad. Learning curve. If I order new thermistors, what is the process of placing those in the brass tubing again? Are they naturally form filling with some sort of adhesive to keep them in there? Or do I need a special compound to get it to stay in the brass tubing?
Tomorrow I plan on buying all of it, the wires, the thermistors, the two new boards, because I can get them on amazon for fairly cheap and the software side I don't have a problem with. I can do that just fine.

 

I was thinking about going with this hotend, as the videos for upgrading seem to think it is one of the better options out there and modifications to make it work are minimal.

So in that case since this comes with it's own thermistor and i was already planning on getting one, this one seems to come with all the parts needed, I was thinking about getting this and the boards. Once I get all three I will let you know how things turn out, but it could be a while. Thank you both for all of your help.

 

Alright guys...bad news.
I have the new e3d v6 installed, new arduino board and RAMPS. Even tried two separate thermistors with the new e3d v6 hotend...I am still getting the same issue. Where do I even go from here?

 

Hang on.
Followed the wires. The thermistor was connected to what the heating element should have been connected to. I connected them back to the appropriate wire and now the thermistor appears to be working? But the heating element jsut keeps raising in temp. It doesn't stop for anything...

 

I have to apologize guys...the heating element was conected to what the thermistor should have been connected to. The thermistor was connected to what may have been the fan? And the fan was connected to the heating element...Things are back in place...will try a test print here soon...
