Hi gencab, just now saw this. I know you didn't buy from us, but if you contact us (Filastruder) using the contact page, we might be able to help.

Sorry you had a bad experience with M3D, seems you are not alone unfortunately.

Detailed documentation for what you're trying to do doesn't really exist for the simple reason that your approach is an odd one. Instead of using the Duet PT100 daughterboard like most everyone would do, you're using a third party board.

This is like buying a Honda Civic, and then then being upset that Honda does not provide detailed instructions for installing a Ford engine into the car.

I don't know why you spent 30 minutes of searching to find that page, if you go to the Duet documentation, type in "PT100" in the search box, that page you linked is the first result.

At any rate, the info in the table does match, though it is for generic PT100 boards and Duet 0.6/0.8.5. Assuming you have this specific board from Adafruit:

https://www.adafruit.com/product/3328

Then look at the schematic for the Duet 2 Wifi:

https://github.com/T3P3/Duet/blob/master/Duet2/Duet2v1.04/DuetWifi_Schematic_v1.04.pdf

Connect the Vin pin on the Adafruit board to pin 8 of the SPIO temperature sensor board connector and so on.

@dc42 said in Duet3D-2 New install uncertainties:

I think the reason nobody has ported any other firmware to the Duet is that RRF is so hard toi beat. Whereas RRF has been so successful that others have already ported it to LPC1768/1769 boards, and a port to STM-based boards is under way.

Gotta say I agree with that. No way I'd go back to Marlin after experiencing RRF.

@onerob That'll do it!

I've gotta say, I appreciate the honesty. Happy to knock $50 off a Duet 3 6HC if you want to purchase one from us (Filastruder). Just email support at filastruder.com with a link to this thread, and you'll get a coupon code.

@t3p3tony Just wanted to chime in that as a reseller working with many companies, Duet3D has done an outstanding job of navigating supply chain issues. Well done!

@random_task_1 Your pinout is incorrect.

I've taken the photo in the documentation, and overlaid your wire colors in text. The 4 pin side represents what your 4 pin side is. The 5 pin side represents what your 5 pin side should be. Looks to me like you've got the RX/TX flipped, which is why your screen is powering up (5v and GND are good) but not communicating.

Got the board from @srgallagher13 , it does not present as a USB port. Diag LED is on continuously. We'll work on it and advise if we come up with a solution, in the meantime we've provided him with a Duet WiFi instead.

@nhof I think that's your comment in the resume.g file in Joel's video

Posting this image here because the customer sent it via email, refuses to post to the forum.

Customer further states:

I made a 4 pin JST PA female plug to snap into the duet 3 scanning probe. As you can see the 5 vdc red power is on, >green can is on and the blue is on steady. It is supposed to flash with communications which I have not seen yet. >When near the bed the Cartographer 3D V3 turns blue. When 3 or more mills away it turns off.

Point is the adapter board is using the same wires and connections and works.

I pointed out to the customer that several of his crimps are improperly seated, he's using a cloned toolboard, and that again, he needs to use the forum for support.

@oliof No, I'm referring to the SZP boards that OP claims keep arriving DOA. Have never and will never sell Cartographer.

Just to chime in here as Polyneutron21 bought the boards from me (Filastruder), have tested our stock and they test OK.

With a 2.2kohm pull up and cold temperatures resulting in 208kohms of resistance, you're asking the ADC to accurately measure about 0.03 volts relative to the 3.3v rail.

3D printer thermistors/boards are designed for accuracy around 200C, (at this point, thermistor and pull-up are similar so there's loads of accuracy/resolution), they don't have much accuracy at low temperatures. I wouldn't sweat it.

@mitch Lots of places to shift electronics (ebay, craigslist, offerup marketplace), I'm in agreement about saving it from a landfill. But seems really disrespectful to come here to do it. Just my 2c.

@RodrigoRMaraujo said in Duet maestro - Diag led does not turn off:

I've been buying Duets on AliExpress since 2019

Just curious, since you’ve benefited so much from their work without buying genuine hardware, have you offered to contribute to the Duet development team?

Is that a genuine product? It sounds like a clone. Super bold to come onto the official Duet3D site, funded by purchases of official Duet3D hardware, to sell a cloned product.

You're effectively asking someone to do development work for you for free. You've gotten a fair bit of (free) help so far. If that's not enough, you could consider contacting Duet3D to set up paid development work.

Seems like another possibility is that the ribbon cable isn't fully seated, photos would be useful.

@remzirecep Yelling for help is not a path to a solution.

Posting the aforementioned photo is a path to a solution, as is posting the changes you've made to the code.

You're getting a reply from the lead firmware author. Maybe a little appreciation for that would be helpful too.
