@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:

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

@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.

@jay_s_uk okay, I will try to update the firmware and see, will it help

@jay_s_uk I can try it, but those network faults might brick my Duet, I think. Also, the same version worked well before, so I am wondering, why it behaves like that

Hello @jay_s_uk !

Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.04 (2019-11-01b1)
WiFi Server Version: 1.21
Web Interface Version: 1.22.6

Hello,

I have an official Duet 2 WiFi for several years, and recently (a week ago) I started having a problem - DWC frequently falls and shows "Connection lost: host is unreachable". I have provided the dedicated IP address for the Duet MAC, but it didn't help.

When that happens, I see an error:

GEThttp://192.168.0.200/rr_download?name=0:/sys/oem.json
[HTTP/1.1 404 file not found 75ms]

XML syntax analysis error: root element is not found
Address: http://192.168.0.200/rr_download?name=0:/sys/oem.json
Line 7, symbol 1:

Also, the hotend cooling fan started to stop at certain places (not sure, are those issues linked). Fan MOSFETS were replaced about 3 months ago.

What could be an issue in that case? It is pretty annoying because disconnect often happens during the first commands, and when connectivity restores - I cannot anymore set baby stepping.

PS: printer itself works even during the lost connection.

@droftarts will test for sure but before I need to reprint the carriage Due to heavyweight of Titan with its default stepper, my 'arm' for flying extruder probably tilted LM8UU too much so extruder carriage stopped while effector continued its movement... Yeah, it was loud.

And about bug - pretty easy to reproduce. Set 4th arm in the delta configuration, set some temperature (hotend only should be fine but better both), then run let's say G32. If there is no warning, try some print - in my case it looked like extreme underextrusion or filament clog.

@dc42 yes, it solved also the printing problem. So, in short - if 4th arm is configured, some mechanism prevents the printer from actual printing due to triggering of heater failure

@dc42 yes, cold calibration was without warnings, 40C both hotend and bed as well, now I am going to try an actual Gcode

@dc42 Surprisingly 3 lengths still o_O While config-override is not updated

@dc42 3 length reported in that case.
