Currently studying maths at Vienna University of Technology
Hey,
I recently updated to firmware version 3.1 and I really like that the simulated print times are now displayed in webcontrol.
It would be cool if, after printing a file not simulated before, the actual printtime could be displayed as „simulated time“ in webcontrol.
@shirnschall After trying to get this to work for weeks, I found the error right after posting.
I used the old RRF 2
M106 F25000
to set the pwm frequency when it has changed to
M950 Q25000
in RRF 3.
The fans now work down to around 40% as expected.
@oliof I think I was using .6 or .7 with a long Bowden tube (as recommended on the duet PA website). I have since switched to a direct drive extruder (lgx ace), so this is really no longer an issue for me.
@phaedrux Thank you. Yes, I have looked at the documentation beforehand. I was unsure if I have to use the external 5V input on the duex if I am using the external 5V input on the duet itself.
To avoid confusion/errors I am now just using the external 5V on both the duex and the duet. Everything is working great.
Hi, I have recently upgraded from duet2 + duex 5 to a duet3 6hc with duet 3HC expansion board. However, I am having issues configuring/using the expansion board.
My setup has a small 5V psu that powers the mainboard (and previously also the duex board). When I want to start a print I use the pson pin to switch mains to the 24V psu and turn it off when all temperatures are back to normal. This worked great with the duet2 but since I cannot find a way to add 5V to the can expansion board it is off when I try to configure it/cannot read sensors when the 24V supply is off.
What is the intended way wo use the pson/ext5V when using expansion boards on duet 3?
@jay_s_uk
Thank you for the reference! After thinking some more about it I think the current in both legs of the ntc should be common mode? I will test it as soon as possible.
Hi,
I would like to measure the stepper motor temperature by placing an ntc (100k, without a metal case) directly on the stator winding. However, I am unsure if the E/B field of the motor causes a problem for the electronics/measurement.
Has anyone tried this yet?

Hi, I am trying to get a 120mm noctua nf f12 industrial fan (12V, 4pin pwm) to work as apart cooling fan. I have connected it as described in the documentation and as shown in the image below.
The problem is that the pwm control is not working correctly. The fan turns off at any level below approx. 80 and only turns on at 90 and above.
I have tested two different nf-f12 fans with the same result.
My setup:
I am currently using the duet2 wifi with the duex5 running at 24V with an external 5V supply. I am using RRF 3.4.1 (2022-06-01) and in my config.g I configure the fan using
M950 F2 C"!fan2" ; fan 2 part cooling fans nf-f12. output is inverted for 4-wire fan
M106 P2 C"Adv-Part-Cooling" S0 F25000 ; set fan 1 name, value, PWM signal inversion and frequency. Thermostatic control is turned off
I have also tried adding a 10k Ohm pullup between the pwm input of the fan and +5V as mentioned here: https://forum.duet3d.com/topic/25179/wiring-configuration-of-standard-4-pin-pwm-fans-on-duet-3-mb6hc
Increasing the B-value as mentioned here https://forum.duet3d.com/topic/25127/configuring-a-pwm-4-wire-fan causes the fan to spinn up briefly before spinning back down again.
Hi,
has anyone tried printing the perimeter or even just the outer most perimeter with half the layer height of the other features?
If done in the following order it should work shouldn’t it?
Sorry if this is already a slicer feature. I was unable to find it.
@dc42 Thank you for the clarification 
I have already updated to the new version.
@phaedrux Hi,
yes I am using DWC 3.4.0 as well.
Please download the gcode from github as it was too large to upload here.
Here is the M122 output (just in case).
