Hi Everyone,

I'm part of the team at Modix3D, where we make big printers (up to 1x1x1m, or 60x60x180cm)

We've been using Duet 2 and Duex5 control boards in our printers for the past 2 years, and we're a big fan of the ease of development that RepRapFirmware brings.

I've been working with the team over the past few months to bring some large updates to the configuration and macro files, trying to start to use some of the features that RepRapFirmware 3 bring, in particular G-code meta commands are a game-changer.

One area that we use G-code meta commands heavily is in the homing files. The (move.axes[0].max or min) is something that has made it possible to use the same homing commands across all printers, as it references things from the config.g files.

Things like that have made development a lot easier.

We also use it in the Duex5 enabled printers to do do fully automated tilt calibration, until the tilt of the corners is within a certain range ( less than 0.02mm of adjustment)

While our files aren't the most advanced or fancy ones, hopefully some of our uses can inspire or help you in your own development. We've definitely learned a lot by reading these forums and are hoping to at least give back a little

you can see our latest configuration and macro files on our GitHub: https://github.com/Modix3D/Modix-V3-configuration-and-Macro-files

If for whatever reason you want to store the Z-offset outside of the config.g file (in this example in a file named config_probe.g), here is the method I've found out to work quite well.

This method works for RepRapFirmware 3.4 and up, as we need to use the ability to write to a file using the echo command. It has been tested on 3.4.1

For more info, see https://docs.duet3d.com/User_manual/Reference/Gcode_meta_commands#echo-command

The macro also allows you to automatically compensate for using of a known thickness shim, using the var probing_tool setting at the start of the macro.

Z-offset macro:

var probing_tool = 0.000
; This allows you to compensate for whatever tool you use to measure the nozzle distance.
; It is set to 0.000 by default, you can set this to the thickness of the tool or paper you use for the Z-offset calibration
; A sheet of paper is on average 0.05 to 0.10mm thick.

It's a fairly simple macro, but if there are any questions let me know

@mikeabuilder
I've gone through this list and added all the gcode meta commands, including var and param: https://docs.duet3d.com/en/User_manual/Reference/Gcode_meta_commands

In notepadd++, to change the stylers you can go to language -> user defined languages -> define your language -> pick the language from the dropdown and then you can change the stylers

For the var and param for example. they are in the 3rd group. You can change the styler, or put it in a different styler.

I've used a VERY basic grouping, so absolutely do use and adapt it to your own liking! If you send me a message or a Github pull request I'll very gladly add it to the UDL!

When uploading a filament configs zip with the wrong files, the error message states "fiels" instead of "files"

Version: Duet Web Control 3.4.5

I have updated the UDL I made with better colors based on the latest RRF version, with both a dark mode and light mode skin

I was however not able to figure out how to match the styling of certain parts. RepRapFirmware for example does X200 with the X being either white/black, and then the 200 part having color.

For the life of me, I could not figure out how to implement that behavior, so I just grouped them as one

@grahamsoukup

Make sure to update the configuration and macro files to those compatible with RepRapFirmware 3.4.1

The instructions can be found on the modix support site, and you can download them here

https://github.com/Modix3D/Modix-V3-configuration-and-Macro-files/releases/tag/v3.4.1.a

@ritz One mistake I see is people keeping the negative modifier in the G31 value, as the default value we provide with the printers is G31 Z-3, just so that in the initial setup it

So if you'd for example get a value of 1.25, from the Z-offset maco, and you don't erase the -, but just replace the 3 with 1.25, you'd get a G31 value of Z-1.25 instead of Z1.25. And with that, the nozzle would be 1.25+1.25 away from the print surface.

You can always reach our support directly at support@modix3d.com, preferably with a copy of your config.g files so we can check that as well.

@phaedrux User confirmed that the pause behavior has been fixed

@Trojan3D If you change it to be >> instead of > on the echo, it adds data to the file instead of overwriting it

So in your case it would be:
echo >>"0:/sys/config-override.g" "G31 Z"^{var.Z_auto_offset} ; write the Z-offset to the config-override.g file

This adds the value to the last line of the config-override.g, however you will see it become quite a mess over time, as the echo >> only adds another line

So after doing it ten times, you it would have the G31 Z value added ten times in a row, with the bottom one being the value you're trying to have.

That's why it's generating a separate file called config_probe.g in this example, and then you can load the Z-offset using a M98 P"config_probe.g" in your config.g and homing files

@dc42 Sadly this did not trigger the calibration prompt

Downgrading to 1.24 and then back to 3.4.1 did the trick, it erased the calibration data going back to 1.24 and triggered the prompt going both to 1.24 and then again when going to 3.4.1.

I've created a super simple UDL, I use the night mode in notepad++, not tested it with white background

https://github.com/ComedianTF2/RepRapFirmware-UDL-For-Notepad

Something that would be nice to get added for 3.5.0 would be addressing the info status messages during things such as G32 or G29 commands.

I just tested it out with 3.5.0-rc4 but the messages are still there.

https://github.com/Duet3D/PanelDueFirmware/issues/279

Modix3D created this issue in Duet3D/PanelDueFirmware

closed Add switch to disable status logging #279

It's not possible to set a different idle factor for different axises (axis?)

https://docs.duet3d.com/User_manual/Reference/Gcodes#m906-set-motor-currents

From the notes section:

The I parameter is the percentage of normal that the motor currents should be reduced to when the printer becomes idle but the motors have not been switched off. The default value is 30% and will always be at least 100mA - starting from RRF 2.02 setting it to 0 will disable the steppers after timeout like M18|M84 do and if an axis is related to the motor, throw out the "homing" of it, since it is likely that the position cannot be precisely determined anymore. Note that the idle current is applied globally for all motors and cannot be set per axis.
