New RepRapFirmware config tool

[chrishamm]

@garyd9 This JSON file only contains the inputs you made in the config tool, I thought that is what you meant. The firmware does not update this file, though. If you'd still had that JSON file on your printer, you could have used it to restore the inputs you made before.

Thank you. I have a question on the configuration generated when selecting a PT1000 thermistor. (I'm asking because I'm getting a PT1000 but I'm not quite certain the proper way to configure it.)

The tool generates something like "M305 P1 X501" (no "R" parameter.) However, the duet wiki suggests that a "R" parameter is required for PT1000's (or at least it's shown in all the examples.) (https://duet3d.dozuki.com/Wiki/Connecting_thermistors_or_PT1000_temperature_sensors)

Is it needed?

@chrishamm Any chance of adding the independant Z motor configuration?

[chrishamm]

@garyd9 The 'R' parameter is basically obsolete for Duets newer than the 0.6 because it defaults to 4.7kOhm in the firmware. I'll add it back for consistency, though.

@madhunm Yes, I think I can add it soon but in the meantime I still have to have a look at a few DWC requests that have come up.

Edit: The configtool now generates an extra 'R' parameter for PT1000 sensors.

understood; will look forward to the update when it happens. Thanks!

@bot Yes, support for DueX2/5 is already included. You can configure every heater+motor that is supported on a DueX5.

I'm not sure I'm seeing this, except for extruders. Where can a U, V, and W axis be created?

How would one configure an idex printer using this tool?

On the Duet 2 Maestro, the series resistor is 2.2K, not 4.7K. I think it's best to leave it out of M305 commands and let the firmware provide the default.

[chrishamm]

@dc42 Yes, of course you're right, sorry - I accidentally looked in my outdated RRF directory when I looked it up.

[mikebridge]

@chrishamm Yes, I meant having the firmware update the .json if changes are made to the .g system files manually, but I guess that would be more of a DWC change

Sorry to dig up this thread.
I have a question regarding the thermistor coefficient calculator.
I remember seeing that there were some changes in code for this, but I cant find the thread where it was discussed.

So in the new version I get this:

In the old one:

And that lines up with:

What is the correct value?
Also every time I go in to custom calculation the default R25 value is 10000 instead of 100000

[wilriker]

@obeliks The documentation says

Bnnn If the sensor is a thermistor, this is the Beta value. For the Steinhart-Hart thermistor model, this is the reciprocal of the B coefficient

So in your case

1 / 5090 = 1.96464e-4

though given this is not clear at all from what is displayed.

[OBELIKS]

OK, thanks
Are then the presets wrong?

[wilriker]

@obeliks Which presets do you mean?

[OBELIKS]

Never mind, completely false alarm. The B values were visually so close to old beta values that I was under the impression we are looking at the old ones.
Thank you for the explanation and sorry for the confusion.

Am I crazy, or is there no way to configure an IDEX printer, or any printer with a duex attached, using the configuration tool?

I see no way to add a U axis. I see no way to reference the fans on the Duex.

[dc42]

The online configurator doesn't cover advanced configurations such as IDEX. You will need to edit the config.g file to create the new axis and assign the correct fans. See https://duet3d.dozuki.com/Wiki/ConfiguringMultipleIndependentXcarriagesCartesian

Great work!!

[bot]

@dc42 thanks, I will make my own files.

[dc42]

You can use the configurator to generate most of the commands, by telling it you have a dual extruder machine. Then edit the resulting files to account for IDEX.

[bot]

That is what I ended up doing. I'm well on my way and finally getting a hang of all the changes since I last configured a new printer.
