@Phaedrux Yes it is. Glass beaded pa-12

Apologies if this was addressed before but I was wondering why the choice of using the 5160 and it's built-in encoder input was not used?

Greetings programs.

I was wondering if anyone had encountered any problems with fam rpm signals not showing properly. I know its nothing to be concerned about, but for those of us who have a touch of the ocd, well then you will know what I am talking about.

When on 100%, fam rpm is correct. But anywhere in-between 1-99%, my values are horrifically overpowered. These values are skewed on both out1 and out2 if I try said fan on those channels. I am starting to think its just the quality of the tach sensor inside the fan as my noctua does not show any of these signs. Pictures will be attached below.

My current fan section looks like this.

The fan I am using for my part cooling is this one: http://www.nidecpg.com/fanpdfs/gamma26.pdf
I have the A33998-58 variant

I am using one of these to power it all.

5v feed to the duet3 is also disabled

https://www.amazon.com/gp/product/B07R45W1LN this is the top board

https://www.amazon.com/gp/product/B07MCW4KCM this is the right angle pin adapter

And if you're interested, this is the nvme adapter im using

You can always do what I did.

I got it working after a reboot. But now I have another problem.

My hotend fan is running even though it is supposed to be under thermostatic control.

When the hotend reaches 50 degrees the fan actually turns off

@dc42 Can you not use 2 tacho signals at the same time?

@dc42 Cheers

I was looking at replacing my regular heat sink fan with a pwm model. I looked up the wiring from noctua and they list the pwm signal at 5v. The tool board wiring diagram lists the pwm as 12v. I assume I won't be able to use a 4 wire fan, but instead will have to use a regular 3 pin or just use 2 pins for power it?
