Would be great to have a full backup function in the DWC, now that filament control have been implemented along with all the other macro's it's starting to be quite a bit of information/configeration excisting outisde the easily to backup /sys/. Don't want / need a way to "import" and full backup to the SDcard, but a way to get all the files off it and to a downloadable .zip or something without having to remove the SDcard and insert it to a computer.

External driver(s) "how to".
So i'm currently upgrading my printer from 1 color to 3 colors.
And for that i ofcourse needed one more stepper driver for my third extruder, that being said i thought the space an Duex2/5 would take up just for one extra driver was a little excessive. So i'm opting for the "Driver breakout board" approach to it.
After reading up on the duet wiki and a couple other sites i came to see that the above mentioned approach didn't have a straight forward guide to follow. So i threw this little "How to" together to maybe help others wanting to do the same thing.
Hope this can come in handy for someone, and for gods sake if any of the graybeard's here see something wrong please let me know so that i can correct it!
RE: Can't deploy BLTouch clone (3D Touch) Duet 2 Wifi
Tbh i just think those sensors are next to snakeoil 😂 Given how cheap the real probes are, it's not worth the potential headache and anoyance any of the knocnoffs can make.
RE: PrusaSlicer with enhanced precision and removal of odd flow math
Isn't precise and accurate more or less synonyms? 😅
EDIT: forget what i just said, googled the definisions and disproved myself 🤦♂️😂
RE: Extruder motor suddenly stoped.
Ok I've got it working again. Almost embarrassed to say it, but i think it's 30% user error. Or well i didn't find anything about it everywhere so i strictly didn't know about the "feature"
Most likely it was a bad crimp or connection in one wire that made the initial mid print problem. And after i fixed that, i actually didn't know that the heater had to be on for the extruder to work (it was active but the temp was at 0c ). So in a final last attempt before ripping out the board and looking for shitstains i set the tool to 220c and the bed to 60c (without filament installed) and tried again. Law and behold now it works.
One never know how little knowledge one have before it's acquired!
"Backup" for 12V systems if powerloss?
Well the title pretty much speaks for it self, would it be posible to have a condensator (a biggun one) "module" or something in series with the VIN for the board to maybe assist with the juice needed to store the values and do the minute Z movement needed?
RE: About filament filter/oiler
I've been, and will keep runing a dust filter. It's as sure as the earth is round that it has some benefit.
In half a roll of filament ( in a room without much trafic) the filter is dirty AF.
Every particle kept out of the hotend is a + in my book!

RE: Run airpump from bed heater output
Ahaa, well then i have to rethink this some more, i believe the mosfet need 5-24v on the control side.
Alternatively i can reasign the bed to e1heat, and run the airpump on the bedheat (with diodes), and throw my led lights on fan0.
Run airpump from bed heater output
So now that I've finaly taken the jump over on RRF3, i thought it was about time to finally swap over to berd-air on my CoreXY, and my thought was to avoid potentially letting the magic smoke out of the fan mosfet.
My printer is 12V but my bed is 24v, so i already run the bed via it's own big external mosfet. The external mostfet's signal input is for the time being hooked up straight to the Duets(2 Wifi)'s "bedheat". And the part cooling (5015 12v) hooked up to "fan0".
Now going over to berd-air my thought was to both free up a fan port or at least not blow one with the way larger motor on the airpump. So my thoughts is to run the airpump from "bedheat", and then hook the signal inputs for the external mosfet up to one of the expansionheader heater outputs. Let's say "exp.heater4" just for reference.
Since i'm all green on RRF3 and the use of the "M950" i wanted to make sure i get my shit straight before i deploy the new config.g.
My config.g "proposal" looks the following:
; Heaters M950 H0 C"exp.heater4" T0 ; create bed heater output on exp.heater4 and map it to sensor 0 M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit M140 H0 ; map heated bed to heater 0 M143 H0 S120 ; set temperature limit for heater 0 to 120C ; Fans M950 F0 C"bedheat" Q100 ; create fan 0 on bedheat and set its frequency M106 P0 S0 H-1 C"Part Cooling" ; set fan 0 value. Thermostatic control is turned off
And when it comes to wiring it's pretty much just to hook up the +/- from the airpump to the "bedheat" +/- screw terminals, and the external mosfets signal + to "exp.heater4" and the mosfet signal - to some GND pin? Or did i get that wiring back asswards in reguard to what should be +/- ?
(Didn't quite know what category this fits best under lol)
RE: Electronics cooling fan on RRF3
Or am i missing something?
Yes. See the RRF3 example here: https://duet3d.dozuki.com/Wiki/Mounting_and_cooling_the_board?revisionid=HEAD#Section_Cooling
M308 S2 Y"drivers" A"DRIVERS" ; configure sensor 2 as temperature warning and overheat flags on the TMC2660 on Duet M308 S3 Y"mcu-temp" A"MCU" ; configure sensor 3 as thermistor on pin e1temp for left stepper M950 F2 C"fan2" Q100 ; create fan 2 on pin fan2 and set its frequency M106 P2 H2:3 L0.15 X1 B0.3 T40:70 ; set fan 2 value
Creates sensors for the driver overtemp flag and the MCU temp reading using M308 as S2 and S3. Creates a fan port for Fan2 with M950. Then creates a fan command to link those sensors to fan2 with a temp range of 40-70 using M106.
Note that the MCU temperature must be calibrated to get an accurate temperature reading. See here: Calibrating the CPU temperature
Doing the intial leap to RRF3 now so i'm still a little shaky on the "new stuff" in regard to RRF2
You'll get there. I assume you've seen this? https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview
Between that and the gcode wiki you can get a lot, but some of the more esoteric things such as this require an example and explanation since they aren't really intuitive. But that's what we're here for.
Physically what PIN of the board should I use in this example to connetc the fan? The Fan 2 pin?
In case would it be possible to use other pins? FAN0, FAN1 and FAN2 in my board are already busy....
I'm using FAN2 yeah, if your using RRF3 it's quite simple to assign it to something else to. If your not using your second heater port for example?
Macro buttons on Print tab
Could it be an alternative to add the same macro buttons from the "Control-tab" into the "Print-tab"? or maybe add an extra folder in the macro system for the "Print-tab"?
For instance, i have "Light ON" and "Light OFF" macros in the macro's folder. And it would be nice to have those in the "Print-tab" as well.
RE: 3D GCode Viewer integrated with DWC
Works like a charm!
One thing i would love is a Zoom-slider or a +/- somewhere on the "viewport" to zoom in on the build area. For instance, i'm using a old AF laptop and the touchpad driver is long before win10 si i cant use the "pinch or open gesture" to zoom or heck even scroll.
Other than that @chrishamm has some issues with the sorting on the release section of the git lol. I've installed an old version more than once just by downloading the top one lol.
RE: New heater tuning algorithm
@Exerqtor How many cycles did it take to tune your 330x300x4mm bed?
I didn't look at it tbh! After 45minutes i went downstairs and watched a movie lmao. Just sent a M500 before i went to bed when i saw it was done, then turned off the printer without thinking more about it 😂😂 i just saw it said 4700 something seconds.
