@jay_s_uk @alankilian I have done both - it worked, thanks! Life is a magic if I don't know physics well enough

@dc42 thank you, that was exactly the reason!

Tried to put the firmware into the /firmware folder, update seems to go well, but PanelDue still stays in the Connecting state. But at least DWC works, so WiFi appears to be okay.

@dc42 just tried, terminal shows the percentage and indicates that the installation was successful. But when I try to power it from 12v, PanelDue stays in the Connecting state.

NB: as I was updating from the version 3.0, I had to put the binaries into the /sys, could it try to install the WiFi driver from the /firmware instead (I might have some older version within this directory)

Hello,

I have recently installed the 3.4.5 firmware from the 3.0 version, DWC upgrade hanged, so I have had to install it via the SD card and USB interfacing.

Now, I face the really weird issue - when I turn on the board via the 12V or USB, I can see that it cannot initialize the WiFi connection. If I use the M552 command to stop the interface and start it again, it properly connects to the hotspot. If I reconnect the USB, WiFi connection works, but if I unplug USB and run 12v - no connection happens. If I plug in USB again, connection doesn't happen until the M552 cycle.

This is the output I see from the terminal emulator:

RepRapFirmware for Duet 2 WiFi/Ethernet version 3.4.5
Executing config.g... HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Warning: Heater 1 predicted maximum temperature at full power is 549°C
Done!
RepRapFirmware for Duet 2 WiFi/Ethernet is up and running.
WiFi module started
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.4.5 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2022-11-30 19:36:12
ok
WiFi module is connected to access point skayred-aux-tw, IP address 192.168.0.201

Any ideas what could be a reason for that behaviour?

It actually started working way better with PLA as a side effect

@jay_s_uk yeah, I have Haydn's arms, so the result position should be like S-n-s-n-s-n around?

@alankilian hello, did i understand correctly, that i should try rotate the fan let's say 90 degrees counterclockwise keeping the effector position?

I was also wondering, should I give a try to the remote fan (connected with PVC hose), would that be sufficient for the hotend cooling? My effector is pretty small, so there are no other places where I can mount the fan

Hello, I have a Delta printer with magnetic arms.

Some time ago, i started having a weird problem - when I move effector in X-Y plane, fan RPM varies depending on the position - for example, in 0/+40 it nearly stop, while in the center it has about the normal RPM and works pretty loud. I have replaced the fan with the new and quiet one, after some time I have the same problem again. When I unscrewed the fan, I have found out, that the fan behaves so when it is located close to magnets, it seems that magnetic field makes the bearing loose, until the friction goes to high - that explains the noise.

My effector looks so:

Did someone have the same problem? Is there any workaround without changing the effector design?

@dc42 hello, sorry for the late reply. I have managed to install the latest firmware and Web Control, also tried to assign the static IP to the Duet - some of those measures seems to help.
