  @gbiski said in Stepper motors and Duet 2 - Duet X2 compatibility: @fcwilt Thanks for your reply. The current limit of 2.4a of the duet is per phase ? Because if not I cannot go over 50% for these stepper motors... Well if is not per-phase I've been doing it all wrong. But, to date, none of my boards have released the "magic smoke". Frederick

  @Phaedrux appreciate the follow up. the wording still seemed confusing to me. perhaps they will update the docs to be more specific with the requirement. also thanks for the tip on removing the unnecessary lines, all is working well now.

  @kauedg said in Diagnosing a probably bricked Duet2: How can I diagnose the C4 capacitor of the 3.3v regulation system? good in-circuit esr tester would be the easiest thing, but, when you blow the circuit like that I always recommend replacing all capacitors on the power rail, especially main output cap like C4 in this case... so just trash it and put a new one in, will save you lot of grief later

  PWM might work. It won't hurt anything to try. The main problem will be the fans interacting with each other. All motors are generators as well, and during the PWM "off" moments, one fan might drive the other,etc. I don't know about the flyback for sure, you can check the schematic. I'm about 90% certain the 1.5 is per output.

  @satre said in Will cutting power to Duex5 only cause damage?: M581 Z S1 T0 ; invoke trigger 0 (i.e. M112) when a rising edge is detected on the Z endstop input You can do this for any endstop, XYZE, so I imagine you could use the E3-E6 endstop inputs on the Duex as well if you wanted. Indeed you can. Suggest you add C0 to that command. Although CO is the default, I always like to explicitly declare these things, just in case something goes amiss with a future firmware update which might inadvertently change the default behaviour. At one time, I had an emergency stop button which would act just like a switch connected to an end stop but which would do an emergency stop any time it was pressed. You can also change the "T" parameter to something >1 which will run a macro in which you can put your own commands, rather than simply doing an emergency stop or pause.

  Heated bed thickness

  @deckingman: the adhesive handles 200-220C just fine, only not much more if you want it to last. And if you turn on your 2kW heater with the temperature sensor on top of the plate the adhesive will become hotter than that before the surface reaches 180C. I agree that a sensor close to the top and away from the edge of the hotplate is best for sensing/controlling the bed temperature, and I agree that having the sensor at the heater location slows down reaching final temperature a lot. But I would still like to have a cap on heater core temperature, which is best sensed with the thermistor integrated by Keenovo. I have a hard time implementing these kind of things exactly as I want them with Duet hardware though. A lua interpreter, softPLC, conditional G-code that runs on a timer trigger, whatever would be extremely welcome. Regarding insulation: I am using a ceramic mat that is used to rebuild two-stroke silencers between the hotplate/silicone mat and the support structure, available at your nearest moped dealer. Insulation properties are decent but not great. With the bed at 110C the support structure directly under the hotplate goes up to 50 degrees or so over a timespan of a few hours, I can live with that. At least that stuff won't decompose or burn when something goes wrong. Cork is another option that works well up to 200C and which can handle short-term temperatures up to 350C.

  @Veti will look forward to the conditional gcode @JoergS5 I'm thinking for more along the lines of identifying which tool is present if the machine is switched off and the tool has not been placed back or if an emergency reset occurs. I did think about adding more information but I was thinking of something simple for now.

  Hi, Just one other thing. It's really just about terms. Many folks think of "homing" as moving to 0,0. The firmware considers an axis homed when the endstop switch for a given axis is triggered when doing a G1 move for that axis with a H1 parameter. When X Y & Z have been homed the printer now "knows" where the print head is located in the three dimensional space bounded by the min/max of each axis. At the point the printer is "homed" but that position may or may not be 0,0,0. On my printer the homed position of X & Y are at the max limits of each axis. When homing is complete then I can move to 0,0 which is the center of the bed. Frederick

  Is there any fix to this, I am having the same problem too. And also is there any documentation on how to set up a new sd card if the other one got corrupted. Also when this happened to me there was a little bit of smoke coming out from around the sd card. I assume thats what fried my sd card.

  @BearcatTD said in X Endstop not being recognized: Sweet Jesus. I'm so sorry for wasting everyone's time. Pat Problems like yours can be hard to diagnose over the internet because we sometimes make assumptions that the basics, like things plugged into the correct connector, have already been verified. Glad to hear you got it sorted. Frederick

  @BearcatTD said in Hot end thermistor problem...again.: Changing the M305 and the thermistor number seemed to work! Thanks all! Glad to hear you got it working. As to the heater tuning question I posted - have you run heater tuning at some point in the past? Frederick

  I should specify, I am using a breakout board at both ends so the grounds would split off to their specific connectors from the breakout 2 all three connectos for the sensors on the duet board

  @crchisholm said in no connectivity - no blue light.: Using an older backup (cant find the more recent one) I got the blue light to come on for a short time and accessed DWC. Homed the Y axis, and the light promptly went out half way home and I could no longer ping the ip. I have a copy of the config.g file from one of my posts on this forum. If I remember correctly, that is the only thing I’ve changed. If I find an older version of the SD, can I just update config.g, copy in the newest update file and see where that leaves me? Yes, you can do that. You may need to update Duet Web Control on the SD card it it is very old.

  Unless you are really good with SMD soldering, connecting signals from the LED's themselves would be hard. But a lot of these signals (vin/5v/3v3/heaters) are easily accessible with led's wired to their circuits at the mainboard connectors themselves, power connectors, heater outputs, etc. (don't forget the current limit resistors for them). For the status (wifi, etc) LED's it's harder, though maybe the lines are accessible in easy to solder locations. To be honest, especially if you are not into very fine electrical work, then your suggestion with fibre optics from (eg) clips over the led's themselves sounds pretty good. Lots of flexibility in how you lay them out on the front and quite fun/special too.

  Seems to have sorted itself. I disconnected then reconnected the fan and its working how it should again.
