@tinchus thanks for letting us know what the resolution was.

@pcr bad cable/connector, dead driver, controller board that has gone insane...

@toddel DSF on the Pi has an API suitable for programs such as Octoprint to send the data through. Octoprint would need to be modified to use it. There is a version of Repetier Server that already supports this interface.

@dang472 said in Accelerometer Wiring:

@dc42 Sorry for the delay. I have 2 daughter boards total. Both stacked on the duet ethernet.
The duex5 does not have any daughterboards on it.

In that case you can connect the accelerometer to the daughter board connector on the DueX5.

@ben_pauza said in Expansion tool board immediate heater fault (Duet 3):

@fcwilt A PT1000 sensor may work. I print at very high temperatures and would like to maintain the performance of a thermocouple though.

To date I've only used thermistors. As part of my ongoing education I just got a few PT1000 units to try.

I've heard of thermocouples but know little about them.

Is there any sort of device that can allow using a thermocouple to a connection that supports a PT1000?

Thanks.

In general, the accuracy of limit/homing switches is only a factor if there's something else on the machine that needs absolute registration to those switches... for example, fixtures, which are things bolted to the machine so you can put stock up against them (or clamping fixtures that hold the material themselves), assume their position is correct, and you can start the job.

Most CNC'ers place the material somewhere on the bed, secure it, and then using things like touch-probes to locate the piece and set work zero, and go from there. Working in this fashion isn't effected by the accuracy of the limit/homing switches.

@paulhew

Got it working! Thank you all!!!

@jay_s_uk I powered down as you suggested, changed the plug to pin Fan0 and now it all works ! i have a controllable part fan 🙂 thanks so much for your help, it was driving me crazy ! turns out i was changing things with power on.

@pfn said in Best Z Probe for Duet 3 Mini 5+:

This isn't actually a problem, only one of the 2 switches is aligned to activate.

I think this is exactly the problem, At the time that the main switch activates, the other switch is not necessary at its activation point (e.g. fully pressed or fully released) which introduces a an error. But anyway, you can always fix it latter with babysteps. 😉

BTW, it just occurred to me that now that the inductive probe is gone, I can mount on that small clickey bracket an accelerometer. It's a good position, close to the nozzle, and with convenient route for the wires.

@t3p3tony

Thank you for the explanation.

I do believe I found the gremlin that started this, seemed the power wires to the fan's PCB start to fray and looked possible that they were shorting... but I tossed it just in case it was something else.

I sure hope this repair isn't too tricky.

@justin-0

AWESOME!!!

@bwoods if it's just for shielding then you can use the ground pin on any of the 5-pin I/O connectors.

@oozebot Yes, I get 2 warnings when loading the config. It doesn't seem to matter. Will start a test print with it tomorrow. Unfortunately, I don't know why M999 doesn't work for me in the macro.

@messiahman make some good pictures from your Duet board and post it here

@dc42
ah what I forgot to say.. the tool was completly cold.
I´ve never printed with more than 220 degree.
with the original e3d pt1000 I have the temperature you see on the picture. with a german pt 1000 I have something with 500.
I only changed the toolboard and now everything works fine.
Same configuration and sensor...

Try with a 9-volt battery first to make sure it turns on and triggers. Keep in mind, you need a live and a return line (ideally plus a ground). If the neutral line isn’t open (possibly triggered from a SSR) it’ll still look like it doesn’t work.

As the other have said, If you pass the 9V test, check your pwm frequency and correct wiring.

Also make sure you haven’t blown the SSR. :). I had a few problems with knockoffs so make sure you have a good relay to begin with.

When i use the SD card without any structure, so just put a gcode file on the blank card it doesnt get recognized.
Only when i create a folder on the card, it gets read.
Even i can name it "new folder" and leave it empty the SD card is recognized as such.
So the card appears to need some structure on it to able to be recognized.

Its not that biggie but Marlin does read the Gcodes directly, i dunno if you could change the connect commands in such a way that it detects the card wether or not it has something on it?
detect media or something?
