Should I be switching out my Duet 2s
-
Hey Duet people,
With the Duet 3 Mini 5+ now available, I'd love to hear some feedback on them.
To my questions.
Firstly, I'm currently sourcing parts for a Hevort based printer. Im using a Meanwell SE600 for power + LRS350 12V, plan for dual z leadscrews (currently happy with that config) and single extruder. Is the Duet Mini 5+ the right board? Not trying to go overboard with my first attempt at a full custom build.
Secondly, I have three formerly Creality cartesian printers. Two are running (gen) Duet 2 Wifi boards, and the other a Duet Maestro. Should I be upgrading these to the Mini 5+.
Lastly, should I wait to learn RRF3 on these new boards or should I go ahead and do it on my Duet 2 Wifi boards?
Thanks guys,
Ryan -
If the Duet2s are working for you now I don't see any reason to replace them with the mini5.
I also wouldn't wait to get started on RRF3 either. It's come a lot way in the last year and 3.2 is a stable release. The cutting edge with Duet 3 and SBC still has some work to go before it's on par with the standalone experience, but it's getting closer with every release.

Hi,
I'm keeping my Duet 2 WiFI/Duex 5 equipped printers as they are BUT I did upgrade to firmware 3.2 - highly recommended.
I have one Duet 3 6HC and two Duet 3 Mini 5 on hand that I am testing.

I'd stick with Duet 2 - more so if you plan on using expansion boards. My printer uses a Gen 3 main board and 3 expansion boards but it's currently mothballed due to a plethora of firmware issues which I'm sick and fed up with after 18 months of nothing but grief.
I'm currently deciding whether to refit the Duet Ethernet + Duex 5 and keep the mixing hot end, or scrap the mixing hot end and just run it as a simple, single extruder CoreXY with just the 6HC main board.

With Switching to RRF3 what are the common stumbling blocks (outside of glitches) to look out for? What have some of you had issues with understanding.
GPIO simply seems like a open ended connection assignment system for both input and output devices. This was preferred way to deal with inputs and outputs on complex AV systems.

It's really rather simple. Some changed syntax, some new commands.
It took me maybe 30 minutes to convert my config.g file from v2 to v3 BUT I created the config.g file from scratch so I knew it well.
Those using the configuration tool often seem to never really learn the command set and the syntax.

The pin definitions are the major thing you'd notice for the config. Using M950 to define the pin before using it in a command that references the pin.
endstops, probe, heaters, fans would be the big ones off the top of my head.
Using the config tool to create a RRF2 and RRF3 config to compare shows quite clearly what's different.

I try not to use the config tool simply for this reason. I've spent the last year learning and understanding GCode as I quite enjoy the programming aspect of it.
So to clarify before I dive down the rabbit hole tonight, upload the RRF3.2 firmware via the system page on DWC, then change the config.g file?
Or am I simply better to use the config tool to make a clean slate firmware? @Phaedrux do you recommend just using the config tool for simplicity?

I was using 2.51 (as I recall) when I decided to upgrade to 3.
The steps (at least at the time) required first upgrading to 3.0 and then to 3.1.1 which as the most recent at the time.
The upgrade went smoothly and I was able to re-boot BUT of course I had to edit the config.g file before the printer would work again.

To start with, yes. That way you have a good example of the syntax to start with.

You'll need to update to 3.0 first.
If you still have access to DWC. Upload these 3 zip files, one at a time. Don't extract them. Reboot after each. Use M115 to verify the firmware has been applied.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.2/Duet2and3Firmware-3.2.zip
That will get your firmware and DWC up to date. -

As for a new CoreXY build, should a stick with Duet 2 products, or just go with the Duet Mini 5+?

Take a look at the comparison here to see if any of the differences would make a difference for you.
https://duet3d.dozuki.com/Wiki/The_Duet_family_of_motion_control_electronics
Duet2 can do 2.4A motors. Mini5 can do 2A.
Expansion is a bit more limited at the moment in case you want a lot of drivers, but the plan for the near future is to be able to use 2 mini5 plus boards connected via CANBUS.

This is what I am on right now on one of the units using a Duet 2 Wifi
If might sounds silly, but I just want to cover everything. So do I still have to load up 2.05.1 if I am there already? During the holidays I updated to the latest I could without going to RRF3.
-
Yes I would still upload that 2.05 zip file. Your wifi server is an old version too. All 3 zip files will make sure you have everything you need in place to go forward to 3.0 and back to 2.05 if need be.
-
if you want to print quieter. then the mini 5 will give you a benefit over the duet 2.
but that applies to slow printing only (up to about 60mm/sec) -
@Veti Thanks for the info. My base printing speed is 60mms, usually doing 80 to 120 for infill. Above that and my printer can't handle it structurally. Thus the hevort based build.
