@samlogan87 said in Which Duet 3 board to get:

Will 2 of them work at a decent speed off a mini

Yes 2 will work well using a duet 3 mini.

By the time we have them available for sale i will have some max step rate comparison figures for you.

@o_lampe you can use the emf calculator here. plug in the motor details and see what the different voltages allow:
https://www.reprapfirmware.org/emf.html

@bartekp do you have a spare fan header. you can use that to control an SSR.

RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.3 ELECTRONICS: Duet WiFi 1.02 or later + DueX5 FIRMWARE_DATE: 2021-06-15 21:45:03

I did the changes PCR suggested otherwise i would never have found the solution 🙂
@PCR
Thanks mate, by removing values from the config as you suggested, the odd behaviour of the software was gone and round pancake worked.

@nick9one1 switch or filament measuring?

Thanks. My Fault. Dotstar on Dotstarconnection. Didn't check the wiring

@jens55

Thank you..

You will have news, I hope that no, but... If you see in the press at the end of January, in the events section, that there has been a fire in Valencia (Spain), by a 3d printer ... it may have been me

@verminsup Yeah!

That Rhinomc.com driver looks perfect for your job although I can't find it on their page, so maybe they don't make it anymore.

It's great you've gotten your machine running again.

@fred-y, oliof

Thank you both for the fast and really helpful reply! Mike

Glad my diagram helped!

I never got it working on the Duet2 WiFi, but have recently upgraded to a 3 Mini 5+ and trying again...

@nick9one1

Maybe I posted too soon. M956 is working now and generating CSV's.

For some reason the Accelerometer plugin doesn't like the files?

the CSV looks ok, with 684 samples but the last line shows the same error as the plugin

0_2021-11-09_20.38.25.csv

@vincent I would say this is a Chinese clone board, you can try to fix it when you replace the voltage regulator here you can find which type you are need : https://duet3d.dozuki.com/Wiki/Connector_and_spare_part_numbers#Section_Voltage_regulators_1

@dc42 Thanks for confirmation. The different pin naming was really confusing...

@merlin246 I suspect that your university WiFi uses WPA2-Enterprise. This is not supported in RepRapFirmware yet, however we have work in progress which will make it easier for us to add support in future.

@dc42 Exact same issue happened to me when building the last printer. Was a bad connection in the CAN cable. I had uses a solder sleeve to attach the tool board wires and when the cables got moved just right it lost connectivity. Re-did it with direct solder and its been fine ever since.

@t3p3tony thank you

@o_lampe assuming that you don't have a DueX connected to the Duet, RRF will know that they are not TMC2660 drivers. Just configure the microsteps/mm value in M92.

@gixxerfast Brilliant!! I didn't notice the jumpers!!

@timtom you will need to fill in the form anyway so that we can contact Filafarm and authorise them to replace your board. Yes Brexit is a horrible mess and makes things difficult, so we will arrange for Filafarm to provide the replacement.

@modix2021 WiFi disconnect screen shot.png

We thought that since the wifi was connecting when the Modix was turned on, everything was fine. Wrong. After some minutes of printing, the disconnect/connect behavior begins again. See screen shot. I have a new board sent b y Modix, so we will put that in next week. The adventure continues.

if you run a direct extruder or a kinematic setup where one stepper is moved around (lokemthe flying X setup on an ender 5) and you get this on high speed moves, it might be showing when you pull the wires around.

OK; that wiring is now exactly the same as my fully working probe + 6HC setup.
I have just done a continuity check from the probe to the board to 100% confirm that is how it is connected.

The Crealty diagram shows the CL version uses exactly the same electrical wiring as the BL one.

So, either the Crealty documentation is wrong re. the probe control values etc. and it needs different parameters in the config file compared to a BL-Touch, or the probe has been damaged by reverse supply connections earlier on..

@chazrogers each tool has configurable offsets
https://duet3d.dozuki.com/Wiki/G10#Section_G10_Set_workplace_coordinate_offset_or_tool_offset

This allows you to have (say) 1 tool at 0,0 on XY and then another tool with a different offset when its picked up by a toolchanger. these offsets are applied as described in the documentation you quoted.

@j3d the reason is that we want file uploads to be as fast as possible, and SD cards prefer large block writes; so RRF uses a 8K write buffer. In contrast, it's rare to download files from the Duet, and other file reads from the SD card don't need large blocks of data in one go; so RRF uses much smaller read buffers.

@mikeabuilder said in All All SD card data lost after web estop:

none of the files on the SD card are ever changed by the fw

there are some files which are changed:
config-override.g <- every time you send M500
heighmap.csv <- every time you probe the bed and save the height map
*.json within the /sys directory <- various DWC and plugin settings that can change

The firmware binaries and other /sys macros are not changed by the printer. and in the case of the /www directory and firmware binaries, those are on github to download again.
