    • Duet Power Panic - Review request

      Hello,

      First off, let me apologize for the crap PCB design; I am nowhere close to @T3P3Tony or others on this forum when it comes to PCB design / routing.

      Some background: I have my printers on a UPS; however, if and when there is a power cut, depending on how many printers are running, the UPS may get overloaded. Before the UPS circuit breaker trips, I switch off the bed heating to make the power draw a little less.

      I wanted to 'automate' the process and here is what I have come up with: a mish-mash between the Prusa Power Panic and a Duet capacitor bank.

      The goal for this is to enable the bed to be switched off automatically; while allowing printing to continue / duet power recovery to kick in.

      Please note, the Panic_In signal comes in from a non-UPS outlet.

      Please review the attached schematic and board files and let me know if you see an opportunity to make this better.

    • RE: WiFi disconnecting only when printing

      @dc42 ,

      any thing else I need to do?
      I can confirm that this issue exists with DuetWiFIServer 1.22 and Duet FW 2.02 as well.

      THanks,
      Madhu.

    • RE: WiFi disconnecting only when printing

      okay; heres a change in the situation:

      • When I lost the connection to DWC, I sent M552 S1 to check if the board would connect to WiFi. It just replied OK and did not do anything
      • I then sent M552 S0; it gave me an error that the wireless mode could not be changed
      • Sending M552 S1 again switched the WiFi on and the board was able to connect to the network.

      And, I have carefully noticed; the DWC connection drops the moment the pre-heat is done and the printer starts to move.

    • WiFi disconnecting only when printing

      Hello all,

      I Have a Duet 2 1.03 with FW 2.03, DuetWiFIServer 1.23 and DuetWebControl 1.22.6

      The issue I am describing was not present in Duet FW 2.02 with DuetWiFIServer 1.23 and DuetWebControl 1.22.3

      What happens is this:

      • If I am not printing, the Duet stays connected to the WiFi indefinitely; no issues.
      • The Duet stays connected while preheating, mesh bed level and probably for the first couple of lines of printing
      • I havent determined the exact location in the Gcode for the disconnect; but, after about 5 minutes into the print, the Duet disconnects from the Wifi. The blue LED on the ESP turns off

      This happens on ALL prints, regardless of which slicer I use. I have tried S3D, Prusa Slicer 2.0

      I dont know whats happening. Any help would be highly appreciated.

      Thanks,
      Madhu.

    • RE: Problems with new Laser Filament Monitor

      What about somehting like this: https://www.thingiverse.com/thing:3091625
      the part in that thing is just an interposer... but, the skelestruder project has the other parts.
      sensing off of a rotating bearing kinda sorta makes sense to me.

    • RE: Running Prusa MK3 with Duet 2 Wifi

      Hi Florian,
      Other than the filament sensor, you should be able to use everything else.
      Duet3d has their own spin on the filament sensor; it is not compatible with the PR one.

      Rgds.

      P.S. Nice job on the robot arm.
