PID auto tune with fans on?

I've upgraded to an E3DV6 extruder and installed the included thermistor. I'm attempting to do a PID auto tune because I keep getting the temp fall error. I upgraded to a 40 watt heater before the E3d, and haven't had any issues until I used the included thermistor. I run dual fans so I've been keeping the fan speed at no higher than 80% with no issue. Now, even down to 25% I'm getting the error. I'm using S3D and I can't get the fans to stay on during the auto tune. Any other programs that will allow it?

 

Do you have the sock for the V6? That helps with fans blowing on it and it keeping temp.

 

Ah gotcha, I'll have to change the thermistor type. What do I change it to? I haven't done too much with firmware besides tweaking auto level speeds. I haven't had any issues until now so I'm sure that's the problem!

I haven't socked the v6 yet. I haven't even looked at them yet but I'd like to. Those are the silicone sleeves for the block right?

 

You change it to a 5 in the configuration.h tab. Yes the shocks are the blue silicone covers. They only fit the newer cartridge style heat blocks.

 

Thanks for the help guys! After updating the firmware and still having temp drops after 5-10 layers, I did some poking around and found that it my solder job on one thermistor wire was loose! At least it was an easy fix! I wish they didn't have such a thin wire going to the thermistor. And that damn braided insulation is a PITA!
