@dc42
Hey, thanks for getting back, There was an M107 in the gcode file, which the slicer added and it disabled all the fan ports. one of these fan ports was powering the Arduino.

Hi,
I am using i2c to communicate with an arduino as an external controller. I use the M260 command to send bits to trigger the arduino controller. I also use M400 before this line as I realized i2c would not trigger somwtimes in the cgode without the M400.
I am able to get this setup working with Tool1. But during a print where I have two tools, after I change tools from Tool2 to Tool1, the i2c command never issues. I found this happens only after tool changing.
I have to restart the machine for i2c to be working again.

Running Firmware 2.03 on a duet2+duex2 board setup.

@dc42 Yeah, I guess that makes sense. I did get a build done after I downloaded CoreNG-dev3 yesterday.

ah, that was it. i followed the build instructions for 2.03, didn't realize they weren't updated for V3.
thanks.

Hi, I was trying to build the newly released Reprap v3-dev on Github using Eclipse and i ran into the following error:

Is there a simple fix by just changing the variable type or is it something more that i might be overloooking?

Thanks

Thanks a lot.

hey @dc42, I was able to use the custom firmware. I want to change the name( instead of 2.03beta3 (2019-03-25b6)) to something that i wont mix up with the original version. any suggestions on how i should do that?

Thanks for that correction. All projects build.

Thanks for all the help! finally got a build running.
im writing a code to add a linear voltage pyrometer. i have written the code but now im getting the following error:

Return without value, in function returning non-void GCodeBuffer.cpp /RepRapFirmware/src/GCodes line 501 Code Analysis Problem

do i decided not to build the duetwifisocketserver project, but directly build reprapfirmware. i ended up avoiding most of the errors i was getting but now im stuck at this:

I checked the path for syscalls.o and the file exists in the directory.

what path do i set for esp8266? i cannot locate the esp8266 folder in ...\arduino\hardware
I also downloaded esp8266 toolchain from http://gnutoolchains.com/esp8266/ which has xtensa-gcc because I coudnt locate the arduino path.
Im still getting the same errors as before for DuetWiFiSocketServer

Changed the manes of all projects, and I was able to build CoreNG, FreeRTOS and RRFLibraries. While building DuetWifiSocketServer ( release config) i am getting the following errors. The Readme file in your repo suggests adding XtensaGccPath. how do i find this on my system or do i have to download and add this seperately?

I built CoreNG and FreeRTOS before building this. it seems that some fles are missing. PS I used the branches that were mentioned in BuildInstructions.
