Error when setting up independent motor bed levelling on CoreXY

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.

@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).
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.

@sebkritikel By all means! Bear in mind that I have made no changes of my own beyond what was discussed/posted in this thread (except for the fans but I find that irrelevant given the topic) - in other words, the new firmware is an amalgamation of the code cited here. In any case, I will link all relevant code snippets below in the hopes that they serve someone in the future.

config.g M671 X105:105 Y0:150 S5 ; leadscrews at left (connected to Z) and right (connected to E1) of X axisThe only discernible change I see is the change from S1 to S5 - maybe thats all it took?
old M671 X105:105 Y0:150 S1 ; leadscrews at left (connected to Z) and right (connected to E1) of X axis -
I tried changing from S5 to S1 and I observed no difference in the way the printer behaved.
As a side question, how do I mark the thread as Solved?
-
topic tools, ask as question, then topid tools, mark as solved.
