Error when setting up independent motor bed levelling on CoreXY

@Phaedrux I concur, tilt correction is a more accurate term.
Also my full config.g:

M584 must come before any M350 or M906 commands. https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping
After that is fixed, definitely try running each line of homeall.g through the console to see where the issue is.

I've put the ;Independent motors leveling section right after the drivers assigning part of config.g and it has made no difference. As a side note, is there a resource I can follow about the recommended sequence of gcode and/or what are good practices when setting up firmware (kind of like M400 before M913 which was discussed above)?
I get the error on the "G1 Z5 F420 S2" line.

I think the M913 and M584 both have notes in the Duet GCODE Wiki saying what other commands to look out for (M913 is a little less clear when it comes to the note on M400). Many other commands have notes/dependencies for other commands.
I get the error on the "G1 Z5 F420 S2" line.
That... doesn't make sense why it would fail there? For kicks, could you try changing the S2 to H2 instead? For your application, and being on 2.05.1, S2 and H2 should function the same.
-
No change.

No change.
As a test reboot your printer and enter that command (G1 Z5 H2 F420) in the DWC Console, just to be sure it is generating the "not homed" error.
Thanks.

Every gcode is documented here: https://duet3d.dozuki.com/Wiki/Gcode#main
It's a good idea to check the relevant gcodes when trouble shooting.

How is your config.g laid out now? Can you post it again? The M584 should be above the M350.
The homing file you've posted is from the /system folder right?

@fcwilt When I start with (G1 Z5 H2 F420) as per your suggestions I get a little but further, namely to G1 X5 Y5 F600 (line 8 in homeall.g) and I get the same error (Error: G0/G1: insufficient axes homed).

It really seems like your endstops are not actually working.
Can you confirm what firmware version is installed with M115?
And then can you confirm that the status of the endstops changes when you click them by checking with M119?
Earlier when you send M98 P"config.g" it didn't seem to echo anything back. Can you try again? There should be at least some response.
-
The result of M115:
M115 FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.05.1 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-02-09bM119 correctly reports X and Y endstops (first/bottom is homed; then/middle is not; last/top is not for X and Y but I was tapping the nozzle to trigger the piezo):
M119 Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: at min stop M119 Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: not stopped M119 Endstops - X: at min stop, Y: at min stop, Z: not stopped, Z probe: not stoppedNo echo on M98 P"config.g" only green background on the message.
-
I guess your config.g is stripped down enough that some of the usual things like showing HTTP and FTP enabled etc aren't present, so there's nothing getting echoed.
Can you try adding M117 "Loading Config" to the end of config.g and when you save and reboot and send M98 P"config.g" again it should at least echo that.
Ok it looks like endstops are reporting correctly.

-
When I run M98 P"config.g" I get no new messages in the console but I see a "Loading config" floating message in the bottom right part of DWC.
My homeall wasn't matching what you have laid out. The difference was the H1 instead of S1. In any case, there is no change - same behaviour and error. For the sake of completeness I ran that line by line as well and it again fails on G1 X5 Y5 F600 with Error: G0/G1: insufficient axes homed.

I don't understand what you mean by "get a little further"?
I just wanted you to execute that one command from the DWC console right after a reboot BEFORE doing anything else.

By a little bit further I mean that I manage to execute more lines compared than before i.e. a bit further down the list of lines. I might have misunderstood you then. The (G1 Z5 H2 F420) command executes fine and I'm able to get to G1 X5 Y5 F600 (line 8 in homeall.g) before I get the error.
-
Ok at least we have confirmed that our config.g is being executed. You can delete the M117 now if you like.
At this point I think it may be useful to backup your current /sys folder files. (check box to highlight all files and then right click and download as zip.)
And then try a fresh config set from the web tool. something is wrong in there and it could even be hidden characters throwing it off. A fresh set of files would cross that off the list.
https://configtool.reprapfirmware.org/Start
If you have a recent config.json file in your /sys folder you can upload that to the tool to get your basic config settings populated, otherwise refer to the values from your existing config.g.
Bear in mind that you would need to manually add in the drive mapping for the second Z driver.
-
I was actually going to bring up creating new config from scratch myself. I will do that (hopefully) tomorrow evening and report back.
Thanks all who tried to help!

Thanks.
So the line G1 X5 Y5 F600 is the command that is generating the error?

Yes that line should back off the endstops fine because the endstops have already been triggered, which makes me think your endstops are inverted, but your trigger test with M119 seems to say the endstops are fine.

I confirm that after setting up the firmware from scratch everything works as expected. There are still a couple of things that need to be ironed out but I think they go beyond the scope of this thread as tilt correction works.
Thanks to all who helped, I wish I could buy you each a beer!

Glad to hear its mostly sorted! Any chance you could post the relevant updated files for us to cruise through? Would be interesting to compare & learn from.
