      This has been driving me crazy for months - can confirm console output is restored for G32 (and others for me) with with 2.1.1

      Thank you.

      It's also worth mentioning that the Duet 3 will keep its config.g parameters while the Pi reboots. When that is the case, the Duet 3 remains functional quasi-standalone mode with the previously processed configuration. If waiting 20s after a hard power failure is an absolute no-go, perhaps it is a better idea to use always-on fans or even a small UPS.

      @kraegar said in M220 apply to only printing moves:

      I'm talking about for a print already on the printer and printing... you know, like when you'd say "oh, I'm printing too fast, let's slow it down a tad..."

      Ah... Understood.

      Slice thermistors

      Stupid question? What is a "Slice thermistor" - Is this an extra thermistor I should purchase for my Duet 3?

      On my existing printer running Repetier I have one thermistor for the hotend and one for the heated bed.

      It's a high temperature thermistor intended for hot ends, made by Slice Engineering, https://www.sliceengineering.com/shop/high-temp-thermistor. So it does the same job as a standard hot end thermistor, except it can go to higher temperatures.

      Unfortunately, the high resistance at low temperatures of this and other high temperature thermistors make them difficult to read at low temperatures when using the ADCs built into microcontrollers. We could make a daughter board with a precision ADC on it to better read these thermistors, but we already have other high-temperature options such as PT100, thermocouple, and PT1000 (which requires no daughter board).

      Though not a safety device per se, if I had a thermistor on the heater itself, I might be tempted to just connect it and set a maximum temperature for it, if only to have more instrumentation. (I'm kind of a fan of having instrumentation, as anyone who has seen the dashboard of my car will tell you.) Having more data available about what's going on is useful when something starts not doing what you think that it should.

      As a shutdown trigger, I don't think that it can be compared to another one with the firmware, but it can have an upper limit for itself. If it were (As an example) 150°C, that's probably fine for anything up to a 110°C bed, but wouldn't give you nearly the warning for a 60°C target bed temperature, though a human watching the temperature graphs might notice a discrepancy if the heater was starting to lose good contact to the bed surface.

      Human attention is one of the best (and worst) safety mechanisms.

      As a follow up, remapping driver 2 to Z caused issues, extruder wasn't turning, and getting "Error: motor phase A disconnected on drivers 2"

      Removing driver 2 resolved it.

      You could use a Adruino Nano and use the Fan from the Duet.
      Write a Sketch for Example aslong as the Fan is "on" turn the Servo I don't know 90° Degrees.
      After the Fan is Off turn it back.

      Should be not to hard to wirte. 😉

      @alex-cr I haven't printed anything yet as I wasn't sure of my results and have been trying to get some ringing under control first.

      My values were: A=0.1214 B=0.1786

      I tested using PLA at 210c on a Titan Aero with 0.4 hardened steel nozzle. I've never had skipped steps that I could tell during normal prints.

      I'll have to run the tests again with smaller intermediate values as you suggest. Get some more data points and then actually try and print something.

      Ok, my fault. Didn't have the 12v_EN jumper on. Only the 12V on the fan select.

      Connecting as you recommended and inverting the PWM works a charm. Thanks!

      Using it as an upper limit in this case would be the ideal situation.

      I think he'll be putting them up soon, but if you email him he can probably get you a set. Maker@713Maker.com

      These would let you use your trick trucks, the magball arms, and the Smart effector.

      Issue is resolved, was something strange going on in my slicer(s) with sphere prints. Not sure what all contributes, but it was having 4 perimeters + 4 bottom layers. I lowered that to 3 perimeter, 2 bottom layers, and they print beautifully. Worked to resolve it in both s3d & slic3r.

      As for the steppers, I did lower the currents a tad from where they were. Didn't have to be 50%, but did have to go down some.

      Could you use styrene-acrylonitrile (SAN) instead of HDPE for the side panels?

      HDPE: https://plastics.ulprospector.com/generics/27/c/t/polyethylene-pe-properties-processing/sp/5
      SAN:
      https://plastics.ulprospector.com/generics/47/c/t/styrene-acrylonitrile-san-properties-processing]

      SAN has a high Flexural Strength, and 1200X800X4 mm sheet is ~35€ and is transparent.

      What are the important mechanical parameters of the plastic panels of the railCore?

      Ok, I set it to 32 steps for x/y/z, homed, and then re-ran my test. I am seeing results smaller than a full step now. Perhaps I'd done something wrong in my past tests, it's been a while since I tried that.

      The WiFi firmware version didn't change with the 1.18 release.

      We could produce the table you suggest, but it would contain a lot of "don't know" entries because when we upgrade DWC and RRF at the same time, we don't normally test different combinations of versions together.

      For version 1.18.1 onwards you will be able to go to the appropriate Release in the RRF github repo and view or download the complete set of files for that release.

      I think things are looking better. I took everything apart once again in all 3 towers. Stripped the belts, idlers, steppers, all of it.

      Found two possible things… one, my pulleys on my steppers weren't as well aligned as they could have been. Adjusted that, which cleaned up the belt path. (They weren't bad, just a tick off)

      The other is the Z stepper wiring was directly laying on top of my 12v PSU's output ports. Not sure it was definitely getting any interference, but it's probably something to avoid. The first layer looks better now, so it's promising that was it. Need to run through a few prints to see.

      Some notes based on questions I've gotten - test your sensor, mine's marked for pitch & roll, but be sure you know which is which before you mount it. The output is Actual Roll, Deviation from starting Roll, Actual Pitch, Deviation from starting pitch… as I have it in the code above. There are lots of other outputs you can enable, just by removing the comments for them. The ones I'm displaying are the kalman angles. For testing, especially with a different sensor, I'd enable more of the output.

      maxDev is defined as 10... and not currently used. You can see I've commented out the bits for it in the output section, but that's where you could set it so that if the angle is more than 10 degrees from the start angle, send a hard stop / pause / warning or whatever to your printer.
