Place to show off PCB Effector assemblies

Ahh good to know, now I need to find them in 24V and that would be perfect!

Can your confirm if the 12V ones work properly with PWM?

9.5cfm out of these. PWM works fine.

If you mean the 40x40 then I don't know the 30x30x10 fan I have - 5v one, will work at 12v but they do sound like they are working hard.
I just pull 5v off the duet 5v rail and ground it via the fan0 GND pin.

Yep, they do. I can run them from 25% to 100%

For my part I used these blowers fan 24v 404010mm : https://www.aliexpress.com/item/2PCS-Gdstime-40mm-40x10mm-4CM-DC-24V-0-1A-Mini-Turbo-Blower-Cooling-Cooler-Fan-For/32799434002.html

10.25CFM, 24V works with PWM (without tuning M106, with default frequency F250)

thanks for the link, I've just ordered a couple as for some reason the standard fan+shroud didn't fit my smart effector correctly. I just hope not to get burnt by Ali express again. The bed heater I ordered from there got lost in the post but they favoured the seller so I lost my money.

I ordered two sets as well. I don't currently run 24V, but the time shipping takes, I might get the itch before they show up.

Mike

Isn't it a lot more convenient to just run the fans from 12V? Sure, you need a step-down converter or a separate 12V PSU, but the choice of fans is so much greater. A DC-DC buck converter is below 10 money units on amazon.

Np, hope you like them. I'll share my fan mount for the smart effector once I finish my duet wifi box

This is my smart effector with fan duct based on David's design (its on thingiverse 2521716).

I have used my existing Traxxas rods with mounts that I put on thingiverse too (2492092). They seem to work very well - my best 8 parameter residual error is 0.005. As you can probably see, using Capricorn bowden tube, which seems excellent. Retraction of 2.4mm seems fine on the 60cm tube on my Kossel XL. Probe works wonderfully well. Not sure if my picture is going to appear though - haven't done this before.

Thank you (how did you do that?)

Jarery

Nice, what material did you use for the fan ducts ?

number40fan

I uploaded the picture to imgbb.com.

I used e3d edge 'very black' PETG for the fan duct. I try not to leave it too long with the hot end hot and the print fan off - OK so far.
