For anyone who's interested in building/using one of these, the documentation, source, schematics, ... is in On Github

The schematic+pcb+bom is designed for Jlcpcb using their EasyEda application so it's trivial (one click) to have one built.

The current state is: the unit works effectively, the Pico has a tiny Wifi antenna so a nearby router is a good thing, and MicroPython for the Pico W is still beta so the wifi code uses blocking I/O which can be a bit laggy.

I also haven't yet written the extra wifi support for Duet3d SBC since only my printer uses that.

@dvmourik thanks. The filament length in those files is already recognised in the 3.5.0-beta.3 build of RRF. I have back-ported the change so that it will be included in the forthcoming 3.4.6 release too.

@dc42 @jay_s_uk Thank you both for the info.

ps: I just tried this and it worked like a champ. 🙂

@sinned6915 Hi, which connections / pins have you used to connect the encoder to the paneldue? Thanks in advance.

@markz You can find the docs for the RRF HTTP API here: https://github.com/Duet3D/RepRapFirmware/wiki/HTTP-requests

@siam thank you so much. I never saw that chooser.

My guess is that option was set to something not in the list (due to 3.3/cnc install) so Dashboard Mode just looked like a radio container name - it had nothing in the list showing. Once I selected Default (or FFF or CNC) it then showed the contents.

@dc42 Thanks, that's good to know. I'll dumb-proof my macros.

Yesterday I ran a bunch of jobs using various unit settings and they all ran flawlessly, so... I'm going to put it down to user error for now.

I am currently reading some information about Bezier and have a last question (at the moment).

Which source/model/sample is a good reference and for testing? It should be an open source program or a file where the format is specified publicly (e.g. Blender, Cascade, OBJ), so it can be investigated what needs to be supported?

@dc42 Thanks so much. It's already very useful.

@dc42 That might explain why it seemed to start failing with 3.3. Still, it was bad code (imho) since it relied on a side-effect and using relative means I should work either way - so I'm good for now.

I'm running in standalone mode.

@fcwilt Sorry, I could have been clearer.

Let me give an example. My mill is controlled by a tablet. I do things like carefully calculate X,Y zero by moving the head and touching the part I'm going to mill. Then I do an M114 to read that zero value in the console so I can save it in case I have to emergency stop. I may also run one or two small jobs (milling a part requires running 10 or 15 jobs). So, there are a lot of little tweaky things happening with console output.

If there's a mistake or something I want to slightly redo I go to my upstairs office and use a large desktop PC to run Fusion360 to 3d model / generate machining operations. While doing that I need a reminder of offsets and results from the last few tasks (or even just know which mill job I last ran) but I can't read the Duet console because I'm at a different computer.

@jay_s_uk That's a really good idea - I didn't know that existed. I think I'll look into adding something timestamped to my config.g that saves logging info and see how that works out.

@dc42 Yeah, thanks I just noticed. I really really appreciate the help.

Spindle works good. Cant do any hogging obviously but it will cut about anything with a light enough chip load and DOC including hardened tool steel. I have a 10-50k rpm electric version too.
Be sure to post some part pics

@dc42 Thank you for the reply.

I've gone ahead and ordered a Duet3 and I'm looking forward to the installation.

Here's the first thing I tried as a test of my conversion - engraving the word Sweet. It's very good - the photo shows hard shadows making it easy to see the cut.

@jay_s_uk Nice! Thanks to your hint I decided to look at the source code and found that on the Duet2 only fan 1 is turned on at power on - and of course that's the one I was using - so I just swapped my two relays (the other controls the spotting laser - no big deal) and now it no longer turns on at reboot.

Thanks.

Iirc dc42 said firmware does not adjust steps/mm with changes to microstepping for external drivers.

So just configure the external drivers to desired microstepping and then steps/mm to as you would for internal drivers
