Ok, was just a thought...

I have had the odd issue with mine from time to time (the "it wont turn off/disconnect" thing) on the old computer we had... cant tell you how many times I had to do a hard restart on it because it would lock up completely.
Never really had temp issues tho...

Also, how much memory does your computer have? and how many other things are running in the background?

Upgraded our computer not too long ago from an old IBM Lenovo/Win XP box with only 2Gig of Ram to a refurbished Win 7 and added gobs of memory to it (12Gig in total - came with 4gig installed) - haven't had a problem since. I can even browse the net, and/or run 123D Design (a memory hog) while running a print with no problems.

Have also run 2 printers from the same computer at the same time with no problems. smile

Simplify3d works very well as well but its not free or cheap.

The only thing that is working is closing and opening repetier between prints. >_>

When I turned it back on it went strait up to 210 then stopped.

I think its repetier... I just turned off the hot end to try to auto-tune the PID and the hot end is still on. If I try to disconnect, it asks "do you want to turn off the heaters?" I press yes, and nothing happens and also repetier doesn't disconnect. Weeeird.

One successful print and now its doing it again. If you look at the graph you can see where it was at 222, then drops when my print finished, then I turned on manual control to preheat to 222, and you can see it oscillating around 211.

Weird how the first one worked...

The fan is blowing at the fins, but it could be hitting the heating block a bit.

So far the RAMPS reset is working.

I'm not even sure what the PID is but I have seen those settings. The thermistor is set to whatever Folgertech provided with the kit.

You know... I forgot about the reset button on RAMPS, I did that and its working this time. Hopefully it stays working.

What is your cooling fan setup? Any blowing directly on the heatblock?

Fan is pointed at the fins.

What thermistor did you choose in your firmware? Did you maybe change itm Have you tried to autotune the PID?

Do you have a fan that hits the nozzle instead of the fins? A part cooling fan will blow on the nozzle, but its output should be very low. It is meant to just cool the layer slighty faster than ambient air. If you have too much air hitting the nozzle the heater cannot maintain temps.
