After a break, I'm back to work on the firmware..
Here's an image of my project folder from eclipse

So I got that to build without errors.. thanks!

however the RepRapFirmware\src\DuetNG folder and the file Pins_DuetNG.h are still greyed out..

Pins_DuetNG.h was the file kazolar mentions modifying in the forums to add additional motor control channels..

under my current build I have access to RepRapFirmware\src\Duet\Pins_Duet.h should I start with this file instead?

Thanks for your help

So I have modified my build as you suggested and now have the following:

RepRapFirmware: dev: Duet2_RTOS
CoreNG: dev: SAM4E8E_RTOS
FreeRTOS: main: SAM4E
RRFLibraries: dev: SAM4E_RTOS
DuetWiFiSocketServer: dev: Release

when I build I get errors.. see the build log attached.
0_1553634404249_build log.txt

thanks.

so I was able to build the latest beta pre-lease 2.03beta2 using the updated recipe from the build instructions:

• package: branch: configuration

---

• RepRapFirmware: main: Duet2_RTOS
• CoreNG: main: SAM4E8E_RTOS
• FreeRTOS: main: SAM4E
• RRFLibraries: main: SAM4E_RTOS
• DuetWiFiSocketServer: dev: Release

I think I may still have the wrong configuration set for RepRapFirmware as I'm using the Duet2 Wifi and the DuetNG folder containing the file Pins_DuetNG.h is still greyed out..

Pins_DuetNG.h was the file kazolar mentions modifying in the forums to add additional motor control channels.. under my current build I have access to Pins_Duet.h should I start with this file instead?

Is Duet2_RTOS the correct configuration of RepRapFirmware for my Duet2 Wifi board? It builds without error and when I uploaded it to the board, the web interface reports back "RepRapFirmware for Duet 2 WiFi/Ethernet" for the firmware name. The possible configurations for RepRapFirmware are below:

Alligator
Duet085
Duet085_RTOS
Duet2_RTOS
Duet3_V03
Duet3_V05
DuetM_RTOS
PCCB_08
PCCB_08X5
PCCB_10
RADDS_RTOS
SAME70XPLD

Thank you for taking a look at this.

thank you for clarifying the branches and configurations..
So I believe I have all of the correct branches and configurations set in my project..
I also installed the new release of Gnu Tools ARM Embedded..
however, when I attempt to compile RepRapFirmware I get errors while building the file: ../src/Movement/Kinematics/HangprinterKinematics.cpp

here are some of the first error messages..

I have attached the console output below..

Hello, we have the Duet Wifi and DueX5 and plan to use it to control a large custom 3d printer.
We plan to control 6 motors off of the Duet3d as well as an additional 5 from the DueX5.
We also plan to use the extra 2 stepper channels found on the CONN_LCD..
But we would still like to use 1 or 2 more..

so we are interested in hacking the firmware to add 1 or 2 more independent stepper channels.
I have seen that this has been accomplished by @kazolar in the forums.

so far I have been able to build the RepRapFirmware 2.02 from source in eclipse on a pc using the master branches of the following:

CoreNG, FreeRTOS, RRFLibraries and RepRapFirmware
I also have DuetWifiSocketServer, CoreESP8266 and LwipESP8266 projects loaded in eclipse

I can get this set to compile without error.

now to proceed towards repurposing pins and adding additional channels of motor control. From reading through posts in the forum.. I believe I need to use v2-dev branches of CoreNG and RepRapFirmware..

so far I have tried v2-dev branches of CoreNG and RepRapFirmware
compilation yields hundreds of errors like this one

'__are_same' was not declared in this scope RepRapFirmware
line 383, external location: c:\program files (x86)\gnu tools arm embedded\7 2018-q2-update\arm-none-eabi\include\c++\7.3.1\bits\stl_algobase.h C/C++ Problem

all of the visible errors concern the same file stl_algobase.h
am I working with the right branches? if so.. How do I fix this?

from @kazolar 's posts I was planing on modifying the Pins_DuetNG.h file for starters.. however the DuetNG folder containing it is crossed out in the RepRapFirmware src folder..

any help would be appreciated.

thanks!

Hello, We are building a large cartesian 3d printer and are hoping to drive 16 stepper motors.

2 for the X axis, 4 for the Y axis, 4 for the Z axis
and 6 for extruders

We plan on using 12 nema-17 stepper motors for the X and Y axes as well as the extruders and 4 nema-23 stepper motors for the Z axis

Upon studying the forum and the documentation, we are planning to use the duet2 wifi, the duex5 and the 2 additional motor signals sets on the CONN_LCD.. however this only nets us 12 independent channels of control.

on the Duet2:
We're planning to run the 2 X axis motors off the 2 Z headers on the Deut2.
We also plan to run the 4 Y axis motors on the remaining 4 motor headers on the Duet2

on the Deux5:
We're planning on running 5 of the extruder stepper motors on the Duex5

on the CONN_LCD:
We plan to run the 6th extruder off of the signals for E10 on the CONN_LCD (Stp10, Dir10, En10, and Stop10)

Is there a way of driving multiple motor controllers with one set of control signals so they run in parallel?

For example could we run our 4 nema-23s on the Z axis via 4 separate motor controllers working off the same signals from E11 on the CONN_LCD (Stp11, Dir11, En11, and Stop11) ? If we can are there drawbacks to running them off of the same signals?

We were curious if anyone has tried to use a second Deux5 custom wired to the CONN_LCD connector to get 5 more controllers?

Finally, we saw talk in the forums about a new version in the works that supported additional motors.. Is there a timeline for this new version yet? Are there opportunities to beta test it before its released?

Thanks for any help!
