@tony73 said in how to recompile the firmware.bin:

now i bought a duet 3 6ch and i don't know how to recompile the firmware to add the hidden 4 axis !! can you help me ? or tell me if I find documentation and where? if I can help you too but I think you know more about me on rrf for duet !!!

See https://github.com/Duet3D/RepRapFirmware/blob/dev/BuildInstructions.md. Development of RRF is currently on the v3.02-dev branch.

Please upgrade the firmware on your Duet 3 to version 3.1.1 and check all is OK before you try to install your own firmware.

duet 3 6ch arrived from 1 day I'm connecting it to the scara !! all different from rrf lpc on skr v1.3 ..... m122 tells me this

version 3.01-rc9 !!! I don't know how to update to 3.1.1 is there a guide? and T: -273.1 can I use this 100k thermistor on duet 3 6ch? it went on rrf3 lps + skr v1.3

I have no idea how to update the firmware !!! thank you all !!!

Download https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip, then upload it to the Duet from the System page of Duet Web Control. More at https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware.

Yes you can use a 100K thermistor.

@dc42

sorry but an example of config.g how to set up a 100k thermistor could you give an example or is there a guide? do I need an expansion card for this thermistor? thank you!!!

@tony73 https://configtool.reprapfirmware.org/Start

Have you seen the config tool yet? You can choose your sensor there and set the values and it will generate a full config set for you to further modify.

Thermistors do not require any other hardware.

@Phaedrux

hello the problem and I don't understand which code to put in the web configurator for that type of thermistor !!! I'm going randomly and nothing changes simplify 3d always marks (T: -273.1)

@tony73

problem solved now goes !! in the duet 3 6ch there was the firmware 3.01 rc9 I reloaded 3.1.1 maybe that was the problem !!!

[Phaedrux]

So you've got it sorted out now?

@Phaedrux

hi yes I have solved it now with version 3.1.1 the temperature is seen by the thermistor 100k !!! question is it possible to load the rrf 2.05 version on duet 3 6ch? because scara on version rrf 2.05 with G0 x-200 y-200 reversed the arm like the scara helios and could go in the unreachable area !!! but with the rrf version 3.1.1 it doesn't go anymore !!!! thank you !!

example scara helios from minute 0: 50 to minute 2: 02 inversion in the unreachable area !!

@tony73 No it's not possible to run RRF2 on the Duet 3.

I'm not familiar with any changes to scara movements. I suggest you post a new thread with that question.

@Phaedrux

hi now everything works! also the inversion of the arm to print in the unreachable area as scara helios !! used rrf 3 lpc with skr v1.3 I had this card and I took the opportunity to try rrf3 with scara !! since it works well I bought duet 3 6ch. I would like to recompile the firmware to add this in scara kinematic cpp "" "motorpos [3] = irntf (-1 * (theta + psi) * stepspermm [3]);" "" "" "to have a fourth hidden axis that keeps the extruder always parallel to axis an axis. with rrf 3 lpc and this very detailed guide https://www.jayuk.org/compiling-and-running-reprapfirmware-on-an-skr-1-4-and-other-lp17xx -boards / and a bit of luck I had recompiled the firmware. I am little expert of this thing I would like to recompile with windows the firmware and try it with duet3 6ch. kindly @ dc42 gave me the link to do it
https://github.com/Duet3D/RepRapFirmware/blob/dev/BuildInstructions.md but I can't prepare everything, it is possible to have help video link or anything else would be fine !!!

[dc42]

@tony73, if you tell us what you are having trouble with, we will help you.

Can you explain in a little more detail your extension to the SCARA kinematics? If it is generally useful, I could add it as a new kinematic type.

@dc42
thank you for the answer I have to fix the 4th axis on scara cleaner and I will make a video to show you what I would like to do, thanks again !!
