    • RE: Duet3 freezes

      Good morning!

      Just wanted to finish this thread by confirming that it is (was) a power-supply issue.
      yesterday night after almost 3 hours printing i was able to capture the problem:
      hevo_fail.jpg

      It was a cheap Chinese brand 480W power-supply and the time increased from 1 to 3 hours because i did some re-soldering for the transistors inside to get them align better to the heat sink (in this case aluminum block connected to the chassis).
      Anyways i received yesterday brand new MeanWell power-suply and hope that it will finish my waste of filament for good.

      Thank you for your help!

    • RE: IR sensor and 2 differen Flexplate system surfaces

      @dc42
      Thanks again for the ultra-fast response.

      I thought about it but this will involve calling this macro before every print.
      I was wondering is it possible to make it more permanent - like to change the value for good in config.g/config-overwrite.g from PanelDue (or something like this), until next macro is run?

    • IR sensor and 2 differen Flexplate system surfaces

      Good morning/day everyone,

      I know it is a pretty newbie/stupid question, but can someone please point me in a direction on how to do a simple (or not so simple) thing:
      Currently i have a Buildtak Flexplate system with two plates with different surfaces. First one is a Buildtak for general printing and the other one is using "Painters tape" for printing of flexibles and Nylon.

      Is it possible to make some kind of macro that will change Z offset value depending on plate currently in use?

      Printer is using Z-min end-stop for homing and IR sensor is used for bed leveling only.

    • RE: Paneldue screen protector

      Hi,
      i just went to a local shop who sell/install screen protectors for tablet/smartphones and they cut a peace for my 5i from a slightly bigger screen protector for a tablet.
      No problems with it so far!

      Whatever you choose must work with it as PanelDue is a restance type touch screen.

      @dc42 said in Duet3 freezes:

      Did you power the machine down and up three and a half minutes before you ran the M122 command? If you didn't, you have a power problem.

      No i did not...

      Yesterday i was trying to capture the power-supply on my USB scope, but as you can expect - it did fail shortly after my laptop battery depleted
      I think to repeat this procedure tomorrow and hopefully this time will be able to catch the spike (if one)

      Today i did a quick "stress test" for the PS (bed heated to 110 and hotend to 260) and i think i did get a power drop but it did not reflected on the Duet.

      In the mean time think to purchase new PS - to be on a safe side.

      PS
      Thanks for the advise on the grounding - will do it. For sure it will not hurt (especially considering that i use IGUS bearings everywhere).

      Updated PanelDue to 1.24 as suggested - same behavior when problem occurs. I did managed to notice that on the problem display restarted.
      This time after hitting reset on the display (which didn't made it operational as it was before) i did disconnected and reconnected it back and it worked (I was able to home the machine while the nossle was still hot).

      Worth mentioning that i disabled completely the second extruder for this test in config.g - because i don't have motor connected there yet.

      Here is the M122 reading:

      I was monitoring machine closely this time and measured the temperatures on the drivers an CPU. E0, X, Y and CPU both read around 36deg on the top ceramic part Z was cooler to touch and I dint measured it. Also all the voltage regulators were a bit cooler to touch.

      Here is the result of the M996 command:
      06062020_5thrun.txt

      One thing that bother me at this point is:
      can it be a PS problem?

      Reason for the question:
      When it happened i immediately looked at the DWC and saw main voltage reading increased 5>14>23.9V ...
      it was in less than half a second though so i didn't manage to see the other reading for 12V.

      P.S.
      and while on the Power-Supply theme a question:
      I saw your Z-Bot images and wonder - shall i ground all the motors and frame to the PS and Duet? I mean can this be a problem that i didn't do it?

      my PanelDue FW is 1.23.2

      no error messages on the display or DWC upon freeze.

      current config files:
      config.g config-override.g

      and because i did power-cycle of the machine (decided to go to bed and then i saw your answer) on boot i discovered the log file in the System part of DWC:
      05062020_3rdrun.txt
      but it seems to be empty

      At the moment - no, but i touched all major components when it happened for second time and they seems "OK"...
      This was my thought at the second freeze...
      ...because on my first machine (old i3 clone) i had overheating issues when i first installed TMC2310, but they were way much hotter than all the components on Duet now (burn finger within less than a second).
      Also i cannot understand why display stops responding to the commands, but still shows all information on the main screen correctly.

      Can measure the temperatures if you advice to do so

      @jay_s_uk said in Duet3 freezes:

      The mesh bed levelling issue is only present when the duet is attached to a raspberry pi.

      Completely forgot to mention - the board is in standalone mode.
      @jay_s_uk said in Duet3 freezes:

      Can you also post the gcode file thats causing you an issue? Or is this not restricted to a particular gcode file?

      Last two of the files attached - tried only with this one for the moment as i want to print a case for my board.

      Edit: it is stopping approximately at 4th layer
