  @DDD said in Connecting a tool board to Distribution board CAN_OUT: Seems like the RJ11 connector is the one to blame If you don't mind could you do a close up of it? and which tool was used? Might be good to add to the knowledgebank of the hivemind to try to understand why it turned out the way it did.

  @droftarts Thank you. I have a single extruder so I will use the extra stepper driver e.g. M584 X0 Y1:4 Z2 E3

  @psyblue, thanks for sharing that. I did some 5V short-circuit tests on a V0.6 Duet 3 and found that L4 overheated and started smoking fairly quickly. I did this several times, but for no more than about a minute at any time. No components failed. The problem was that the actual internal current limit of U10 turned out to be much higher than its rated output current. As a result of these tests, we added a 3A PTC fuse feeding 5V_EXT on the latest Duet 3 revision, and increased the rating of L4. I am still surprised that U10 failed on your board, and I suspect that the flyback diode may have failed first.

  Not from what I can tell. Nothing seems warm or looks damaged. I live in a very humid climate, but have checked all ICs and traces for corrosion or bridging from bits of debris

  @Nuramori I tried right now the same. But as soon as I plug the RX port in on the Arduino (directly from the PanelDue RX) the PanelDue loses the connection. Arduino is supplied with 5V. Did you the same?

  @Phaedrux I was using heater 7 before on rrf 2 , so moved the control pin to heater 7 and it works.

  @theruttmeister it's hard to get an accurate reading because my hotend is fairly enclosed and has a silicone sock on it. the bed was reading 59.5C when set to 60. I'm running calibration prints now so we'll see how it goes.

  I prefer the contactless approach and just wire in (directly with no extras has worked fine for me) A3144 digital hall effect sensors (~$1 ea.) for my endstops and slap a magnet on the moving part. You can home fast and do a slow back and return and the repeatability has been hands down better over time than contact switches I've tried.

  all the design files and schematics are available for the the duet2 (poke around for older revisions) https://github.com/T3P3/Duet/tree/master/Duet2/Duet2v1.04 ^-- if it suffers bitrot in the future try https://github.com/Duet3D/

  @QuintBrand said in Stepper driver input mode?: . I indeed want to do something very similar to the step analyser with the dynamic analysers I sell for my company. in that case you should be able to get away with a bed of nails type setup with pogo pins for the step/dir signals if you need them. for moderate currents you could do the output as well i guess.

  Wow, that's brutal! Never mind. I've got all manner of bits coming and an E3D PT100 here as well. I feel that 350C would be as high as I'll be going possibly for PC.

  @piranha32 said in My Duet2WiFi stopped responding: I'm worried that it may happen again when the board will be installed in the printer, so I'd like to understand what's happened, and protect against it. first reported case (afaik), and turn off the power when working on it as well as don't work on it without a proper ground strap to ground youself about summs it up i rekon.

  Ah I see, so the bed isn't actually heating at all. Have you checked the voltage at the source pins on the board and at the bed itself with a multimeter?

  @dc42 Genuine, I only use genuine. I just tested with known good probe and it was a faulty probe, sigh. So much time wasted. Works fine on Toolboard.. tried getting it to work on io5 on Duet3 without luck though for some reason.

  @baird1fa said in Mixed voltage for 24V fans on toolboard.: @dc42 I’m not sure I follow all of that. So if 24V was applied to Vin and Vin was used to power a fan as the + terminal and the - was connected to the out1 PWM terminal. You would feed 24V into the 12V supply through the fly back diode. But this would only affect out1 and out2 and not the 5V supply because there is protection internally to the 5V supply? So in conclusion it would only harm the 12V output terminals if anything at all? Correct. You could even connect +12V at the OUT1 or OUT2 connector to VIN. Note, I haven't tested this yet, I'll try to do this tomorrow.

  Just make sure the ribbon cable is connected and configured to pass power from the Pi to the Duet and you should be ok. But without Vin you can't test much more than just the basic communication (if you have Vin connected then you might want to leave the jumpers at the default settings which feeds power from the Duet to the Pi)

  @elixirtrip well some info is already here. For now there is a board that can go to can bus without a driver and you can attach your own external closed loop (leadshine, odrive ..): https://forum.duet3d.com/topic/16257/ac-servo-motor-driver-control-by-duet-3-mb6hc-help/5 https://forum.duet3d.com/topic/17148/duet-3-expansion-1xd-can-fd-single-external-driver-controller?_=1592917797395 https://forum.duet3d.com/topic/15975/duet-3-nema-23-closed-loop-with-z-axis-also-using-elec-brake/16
