@jay_s_uk its all e3d volcano, just replaced everything with this build. Granted it is extremely warm and humid where I am right now.

This is what I am using for the thermistor:

M308 S1 P"e0temp" Y"thermistor" T100000 B4138      ; configure sensor 1 as thermistor on pin e0temp

I believe that is correct?

@noblebran if you're using an E3D thermistor, no

M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.060000e-8

Can you confirm what you purchased?

I do not have the e3d thermistor then. It is just a regular type k thermistor. I will order a new one, but I ran it on smoothieware for years and never had an issue. odd I how I don't have a problem now, I am buying a new block that allows the use of a cartridge but the one I have now isn't big enough for a cartridge.

Do you know of anyway to compensate or reduce the power to the cartridge to allow it to heat up less?

The cartridge is 12v also, not sure if that matters. I would think if it is 24v (set up that way) wouldn't it burn up?

Do you mean type k thermocouple?

Yikes, yes it does. It looks like you're running a 12v heater at 24v. Hence the insanely fast heat up. DO NOT DO THIS. Replace the heater with 24v immediately and don't use it until you do.

Okay, thank you!

Can't believe I overlooked that!
