DHT22 are easily available and far more accurate I've found. I used both but standardized on 22's for chamber temps and filament drybox humidity monitoring.

@bot said in New custom IDEX, but S3D and Duet tool changing issues.:

XYZU

Ohh interesting, yeah that is good info to have documented somewhere it is confusing because in the IDEX guide on the site, it has U on the Stepper Driver 3 as well, so it looks like it was just mapping to that stepper number. I'll fix my code now

I have noticed there are a lot of little nuances with the RR coding on Duet that takes some time to figure out!

I appreciate it!

@nhof said in Z-Max End stop? Printer ignoring it?:

he second line M574 Z1 S2 we are actually asking for the Z probe to trigger when the Z reaches min limit. Not what we really want to set up for the subsequent G1 move.
I imagine something like M574 Z2 S1 might serve you better, double check the home sensor state using M119 (or thru DWC) to ensure you have the proper S value

Awesome, I will take a look at these! The G1 syntax specifically could be the issue I was seeing.

@sebkritikel it was my slicer acting weird and specifically for the profile I use for the duplication printing, it was failing.

I may have solved the issue on one side of the IDEX ( the pulley may have been loose... ) but I cant account for the otherside having similar issue.

DHT22 are easily available and far more accurate I've found. I used both but standardized on 22's for chamber temps and filament drybox humidity monitoring.

Since going to 3.2 I am seeing consistent layer shifting on the X Axis. Nothing changed mechanically on the printer, and I thought it was some issue with a stepper, so I replaced it... and still seeing layer shifting (.1 - .5mm ). I haven't been able to pin point any other issues other than the upgrade to 3.2...

Happens on the X and U axis (U is run off the Duex, X is on the Duet), I havent noticed it happening on the Y axis.

I am watching how since 3.2 (maybe even with 3.1.1 but I didn't notice it...) that before uploading a job and immediately after when the job starts I see Buffers were maxed and the error code changes.

@Veti They do sell PT1000s that work natively on the Duet and work in place of the stock e3D thermistor. I am running 2 of them right now and can confirm this. And to the OP - you don't define the T parameter with the PT1000

@dc42

No that was the first time I've seen that happen, after unplugging and replugging it, it worked again. The Extruder body isnt grounded (its on the X Axis gantry, direct drive extruder, so no easy way to ground it. I dont have an extra wire in the bundle going to the printer right now that carries a ground consistently. I could look into running a small ground wire in the bundle to the extruders.

And yeah upgrading to 3.1.1 fixed that stack overflow error.

@droftarts said in Magnetic Sensor - Extruder X reports sensor not working errors:

till feels like an SPI problem between the Duet and Duex to me, ie something glitchy in communication between the two causing the error 4 (Output buffer starvation). I don't know if it is the sensors causing it, or the sensors misreading as a result. One thing I notice is from your config.g is that you have the X axis (X and U) split, with X on the Duet and U on the Duex. I guess you combine these to X with M584 X0:5 after homing X? My thinking is that it would be better to have the motors of each axis on the same driver, and have X, U and Y on the Duet, Z and extruders on the Duex, if possible.

Yeah I am about to print again and I will get the info from them for you.

Also I noticed something interesitng, I just connected to the printer after it was sitting idle for a few hours after powering up. and on connection I heard it reboot the machine. I checked the M122 and saw this:

A Stack Overflow reset out of nowhere? Not sure I've seen that before.

@droftarts @dc42 Thanks!

So tonight I was doing a long 7 hour print, after upgrading to RRF 3.1 on my Duet 2 Ethernet.

The Sensor on E0 that was printing worked fine for ~ the first 4 or 5 hours. Then it had the first "Sensor not working" error, then a second about 4hours later.

The weird thing was after the last one, the sensor went dark. No LED flashing, nothing... After the print I plugged it back in and it started flashing again. Could there be some static discharge issue at play here? (correction - the last event was a "too little movement error" when the sensor was visibly dead) The E0 sensor is the older of the two, I RMA'd the E1 sensor already.

I did see an Error Code 4 come up in the M122, but that happened about hour 2 or 3 into the print, before any "Not Working" error happened.

I am onto another print that I need to get done tonight, but here is the M122 from that (Note I disabled the E0 sensor for this print as I cant have it stop overnight)

I just did the move and to redo the config for my custom IDEX machine with a Duex5, DHT sensors, Filament sensors, a bunch of fans, BLTouch, etc... took about 6 hours to redo the config.g, BLT scripts, macros, etc... Seemed to work out of the gate! I am on 3.01 RC12 and it seems solid.
