Woops I posted to the wrong post.

Here's mine. I used your idea and made one to fit my control board. Makes a big difference. The heat sinks used to get hot but now they get only slightly warm.

I have an M-201 printer and when it works I love it. But the problem is I need a new heater resistor for it. I HAS to be a 24V, 14 ohm unit for the PID values to work. I've been told by Greeetech sales that they DON'T sell a replacement heater for that unit! I was told that I should just replace the ...

Nice. I might copy that, I do the same thing sometimes.

That still doesn't answer my question about running PID autotune.

Even if I change the heater resistor to use the "24" volt on, the PID still will change since the mass of the single extruder is so much smaller it will heat up and cool down much faster than the larger 2 in 1 unit that the PID is ...

Well that's not right according to this link.

I'll measure it when I get home and double check.

I have an M201 printer and found the 2in1 out extruder to be too tempermental so I replace it with a single extruder purchased from you. The problem is that the PID settings are all wrong for the new extruder (of course) and there is no way to run PID autotune. I have firmware v. 1.0.4. If I change ...
