Hey thanks for that great idea. I actually had a noctua fan that was the exact right size for the psu laying around. I just put it in and the psu is at least 1000 times less noisy than it used to be. Awesome!

Re: M2 rev.E - black z motor leadscrew pitch?
Thank you for posting this information guys, I'm really interested in the Duet 2 for my M2 rev D with 24v and V4 because I want wireless connection without setting up pi. and I'd really like the new drivers with all of those benefits. I'm looking for a little more comprehensive build log to give me the confidence that I could do the upgrade without having the printer out of commission for months. The firmware was my biggest concern but I feel better knowing that someone has already sorted that out for the most part.
Thanks for your knowledge contributions.

Re: M2 rev.E - black z motor leadscrew pitch?
Real old post but doing this myself and not finding the pitch of the lead screw.
Wiki says
four start 8mm pitch leadscrew with a metric trapezoidal thread. Four start means that there are four individual threads along the length of the leadscrew; 8mm pitch means that the center to center distance of the thread is 8mm but that is not apparently the same as what they are asking for.
A google of "For start 8mm pitch leadscrew" comes back with a T8 with a pitch of 2mm and lead of 8mm
So really confused as to which to use.. 2mm or the above data of 3.1750 mm for a 1/8"??

Thanks to anyone who can answer this one.

Re: M2 rev.E - black z motor leadscrew pitch?
The number you want is "how far does one rotation of the leadscrew move the Z axis", which is the thread's "lead": 8 mm.
Wikipedia is your copilot:

Use a Sharpie to confirm the diagnosis:
That's in a CNC router with a two-start leadscrew and a 2 mm pitch → 4 mm lead: one turn moves the follower nut 4 mm.
