Looking pretty damn nice if you ask me. You're first to print CoreXYU !!! /me jealous.

If you get Hlidskjalf printing soon we can call it a tie!

Firmware 1.19beta7 includes the CoreXYU support. I hope to release it later today.

Great!
Did my first prints today! Still pretty ghetto and a lot to fix on the printer. I have seen better first layers but still a big milestone in my project!

Now I need more axis than 6 for bed leveling... Next firmware hack me think...

Looks nice!

Why do you need more than 6 axes? You only need 3 Z "axes" for 3-point bed levelling, plus XYU makes 6. But I am considering adding another 3 axes A, B and C sometime in the future.

Well, corexyu use v as a hidden axis so that's a total of four plus three for z.

OK, I forgot it used V as well. You can probably just increase MaxAxes in Configuration.h to 6, change the AXES_ macro to take 9 parameters instead of 6, then find all 4 usages of AXES_ in the code and add the additional 3 arguments. I was planning to call the new axes A, B, C. The only complication I envisage is if any of the gcode commands that accepts axis letters already takes an A, B or C parameter to mean something else; but I can't think of any.

DuetWebControl and PanelDue would need modifying to display more than 6 visible axes, however you will still have only 4 axes visible so that doesn't matter.

Finally got my Due flashed using Bossa.
Bastard wouldn't connect until used the native port.

Will be plugging it up to the RADDS tonight, and wiring up the extruders this weekend.

Still have to build my bed up, have the RepRap 300x300 big bed and a chunk of 1/4" ATP-5.
Plan on using a slab of concrete fiberboard under the heater for insulation.

Regarding axes, about homing the U, from what I gather it should home to the left (X minus).
Cartesian printers support this function for multiple heads, however looking at the code don't see this enabled for CoreXYU.
First need to hack my config... can't wait to see Hlidskjalf moving under its own power

I can post my config once I'm back home tomorrow evening. I home x left (low/min) and u right (high/max).

I am so far behind you guys. I'm still designing mine, and once I'm done that, I have to test all of the tolerances and then I have to save up because I'm just a poor college kid lol. I'm starting to doubt that I can finish by the end of summer.

Dood, I started sketching back in August of last year. First CAD renders were posted on Thingiverse at the end of September. If I can get this puppy solid before a year passes, I'll consider myself lucky.

Also are you also gonna try and do the triple Z axis auto bed leveling?

I have 3 independent steppers on the Z-axis so I will use Z axis auto bed leveling.

Take your time, just ordering and receiving the components can take a lot of time.

Thanks Lars.

Keeping an eye on Github. Though I'll need the RADDS version when dc42 gets to it :p

I was already planning to release beta 8 during next week, and I'll include the CoreXYU fixes in it.

I've committed the RRF source code fixes to CoreXYU configuration to github. I also added the ABC axes in the Duet WiFi/Ethernet configurations, but I haven't tested them yet. Nor have I done a release, because I am waiting for more feedback on beta7 in case anything else has broken, and I have other changes to make first before I write a test schedule.

If I build CoreNG for SAM3X8E, get

'Finished building target: libCoreNG.a'

When trying to build CoreNG for RADDS get:

./variants/RADDS/startup_sam3x.o: (.vectors+0x0): undefined reference to `_estack'
collect2.exe: error: ld returned 1 exit status
make: *** [CoreNG] Error 1

So, built CoreNg for SAM3X8E.

Building RepRapFirmware (beta7+1) for RADDS get the following,

c:/arduino-1.5.8/hardware/tools/gcc-arm-none-eabi-4.8.3-2014q1/bin/../lib/gcc/arm-none-eabi/4.8.3/../../../../arm-none-eabi/bin/ld.exe: cannot find -lCoreNG
collect2.exe: error: ld returned 1 exit status
make: *** [RepRapFirmware] Error 1

You need to build CoreNG for RADDS. I just did a clean build and it works for me. From the message you are getting, I think it may be trying to build an executable instead of a library. In C/C++ Build->Settings->Build Artifact, check that the type is set to Static Library when you select the RADDS configuration (the same as for the other configurations). Or get a fresh copy of the .project and .cproject files from github, Refresh the project, and try building again.

Fresh copies, check.

Okay, set CoreNG to build as a Static Library.
Now makes a CoreNG.a in C:\Eclipse\Firmware\CoreNG\RADDS

However, still can't get RRF to build. Been hammering away on all kinds of settings and Google searches to no avail.
From the Properties>C/C++Build>Settings>Build Steps
It appears the output should be a *.elf (executable), so set Build Artifact to Executable with extension of elf.
Still get an error:

The collect2.exe program should be part of your Arduino GCC installation I think. I suggest you search for it, and if you find it, make sure it is on PATH.

Did that, same message.(added to PATH, in Properties>C/C++ Build>Environment)

Also tried adding (then removing after error) the CoreNG/RADDS directory to anywhere and everywhere because of "ld.exe: cannot find -1CoreNG".
Only cause it's listed in the Cross G++ Linker>Libraries. And done wrong messes up the objects.mk file in the RepRapFirmware/RADDS directory (new error message). Ended up restoring back, just like all the other stuff I tried that didn't work.
Hours of fail, though am getting good at navigating Eclipse and crushing empty Dr Pepper cans.

I'd be very interested in a "walkthrough" to make my own RRF version ( especially for RADDS ) but I failed following the BuildInstructions.md.
I just saw there is a new version of the instructions, maybe now I find the Eclipse compiler... ( Don't try to search for "Eclipse" )

It would be very kind of you David, if you could give some pointers in a separate thread. ( Duet folder here or Duet3D forum )

Edited 1 time(s). Last edit at 06/28/2017 02:49AM by o_lampe.

Right then,

Found 2 issues why the "cannot find: -1CoreNG

1. When building CoreNG for RADDS, eclipse left the "lib" prefix off, making CoreNG.a invisible until renamed to libCoreNG.a
easy fix, in properties>C/C++ Build>Settings>Build Artifact, not only set Artifact Type to Static Library, Artifact extension to a, also set Output prefix to lib. For some reason prefix was blank.
Then of course there was setting properties>C/C++ Build, Configurtion to RADDS active, done way back when 1st importing the project.

2. In RepRapFirmware properties>C/C++ Build>Settings>Build Artifact, set Artifact type to Executable, with the extension elf.
Then in properties>C/C++ Build>Settings>Tool Settings>Cross G++ Linker>Libraries, changed "${CoreName}/RADDS/}" to "${workspace_loc:/${CoreName}/RADDS/}"

Unfortunately after a long list of warning, we get to the old error:

collect2.exe: error: ld returned 1 exit status
make: *** [RepRapFirmware.elf] Error 1

And yes, collect2.exe directory is included in properties>C/C++ Build>Environment>PATH (C:\Arduino-1.5.8\hardware\tools\gcc-arm-none-eabi-4.8.3-2014q1\lib\gcc\arm-none-eabi\4.8.3)
Along with the *make* (C:\Arduino-1.5.8\hardware\arduino\sam\system\CMSIS\Examples\cmsis_example\gcc_arm).

I posted the "Paths" above, because on my next fresh drop of the project RepRapFirmware, will need to add them again, again... so i can just cut-n-paste them off this post.

Maybe you could try setting it on the windows path?

I just remembered, Eclipse uses its own path to search for tools. In the project properties, go to C/C++ Build -> Environment and check the PATH variable there.

Looks like you updated the files from the latest commit, but you didn't Refresh the project. So it's not compiling files that were added or moved in that commit.

Okay, did a "Refresh".
No warnings.
Just the same old error:

Same if the artifact extension is elf.

Somehow you have not picked up the full project settings from github or you/Eclipse have modified them, because several of your settings have been wrong. Here is another one. In the C/C++ Build -> Settings -> Cross G++ Linker page of the project properties, check the value of "Command line pattern". It should be:

${COMMAND} ${FLAGS} ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${LINK_FLAGS_1} ${workspace_loc:/${CoreName}/RADDS/cores/arduino/syscalls.o} ${INPUTS} ${LINK_FLAGS_2}

You seem to be missing the bit that ends in syscalls.o because _sbrk is defined in that module.

Mine looks the same, straight cut-n-paste from my install of Eclipse Neon2 Linker Expert settings Command line pattern:

${COMMAND} ${FLAGS} ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${LINK_FLAGS_1} ${workspace_loc:/${CoreName}/RADDS/cores/arduino/syscalls.o} ${INPUTS} ${LINK_FLAGS_2}

Confirmed file by navigating in Windows, C:\Eclipse\Firmware\CoreNG\RADDS\cores\arduino\syscalls.o

Well the syscalls.o bit doesn't appear in the linker command line that you quoted 3 posts ago, but it does in mine when I link the RADDS build, right after --start-group.

Yea, when I build Lars' fork for Duet, it lists the syscalls.o and builds fine.
'll try deleting the reprapfirmware project and importing it new rather than refreshing it.

EDIT:

Same error

Pikefish seemed to have an identical error,

[www.duet3d.com]

IDK, just seem to be going faster in ever decreasing circles...

Downloaded beta8 bin and wrote and verified it to the Arduino Due.
Powered up and now the PanelDue is stuck "connecting".
Traced all the leads, all contacts are solid on the 4 pin outs Tx to Din and Rx to Dout, obviously V+ and gnd are correct otherwise there'd be no display at all.
config.g and PanelDue both set at 57600 baud.
'bout the PanelDue, really like the "Dark" display, maybe it's just my current mood :p
