For anyone still looking through this thread, the following S3D script will upload the file to your printer (with a timestamp) and tell it to start printing that file much like Slic3r would do:

curl  -F "file=@[output_filepath]" "http://XXX.XXX.XXX.XXX/rr_upload?name=gcodes/[output_filename].gcode&time=YYY"
curl "http://XXX.XXX.XXX.XXX/rr_gcode?gcode=M32[output_filename].gcode"

Copy and paste into "Additional terminal commands for post processing" under the Scripts tab and replace XXX.XXX.XXX.XXX with your printer's IP address or hostname if applicable. As mentioned above, DWC will throw a couple of errors but doesn't seem to impact the print in any way. Happy printing!

@dc42 That was the problem. Thank you very much!

I have an E3D Tool Changer that was working fine on an earlier RRF3.2 revision and now I can't select any of my tools or activate any heaters. Every time I run T0-4 and follow up with T it tells me no tool is selected.

I'm not getting any errors when loading config.g or during any of my manual run of tpre, tpost, and tfree macros aside from extruding without a tool selected, as you might expect. Running T0-4 or attempting to activate a heater seems to just run tpre and then nothing happens.

I've tried erasing the fw from the board and reloading via Bossa but I'm right back where I was.

I have no issues with kinematics or homing and my sensors are working normally.

I'm hoping I just missed something in the documentation but the Gcode reference doesn't seem to mention anything.

Any help is appreciated. Thank you.

Did you ever get any traction with this? I'm contemplating these issues right now and finding myself perplexed why this hasn't been implemented yet. I made a post recently about merging the IR-based filament width monitoring feature from Marlin and was basically shot out of the sky. I could see combining that with this idea could be a powerful combination.

Devs, hear my prayers!

Did a fair bit of searching for this and didn't come up with anything so please let me know if your Google-fu is stronger than mine and I just missed it.

I'd like to make use of this filament width sensor I found on Thingiverse designed by user "flipper" but don't see anything in the Duet documentation that talks about doing this. I'm using a DuetWifi2 and Duex5 if that matters.

Conceptually, I don't think it would be that difficult to program. The board outputs a DC voltage that can be monitored and, depending on the calibration, have the software monitoring that voltage trigger G-Code to set the filament width to the new value. Marlin has this built in, apparently. I was initially thinking of putting it on my Anet but it would be way more badass on my Duet machine. Any chance of this happening?

Thanks!

Mathematically inept person here. I get the principle behind M592 but, despite spending the last 2hrs reviewing vague G-Code documentation and a slew of forum posts, I still don't understand where these A and B values are coming from/how they are being calculated from the measurements you're taking. Can you help me, please?
