Lower case axis letters

theolodian

@theolodian

OK, this bit of config.g:

Gives this result:

So only 10 axis, and must be declared in XYZUVWABCD order still in RRF3.4?

There's a lot of strange stuff going on here. Definitely trying to insist on XYZ?

Here are the console messages from a single startup:

And here is the config.g (I tried declaring and reassigning X Y Z to no avail):

@theolodian TBH I've never tried more than 9 axes in SBC mode and I've just figured out that various codes would fail with lower-case axis letters. I'm going to fix this in 3.4-b7.

dc42

@theolodian axes X, Y and Z are created by default and will be assigned to drivers 0.0, 0.1 and 0.2 by default. You can use M584 to reassign them to different drivers if you like.

Other axes can be created in any order you like. Letter E does not specify an axis, it specifies an extruder. Letter F is not valid as an axis letter.

I just ran the following in standalone mode:

M584 A0.3
M584 B0.4
M584 C0.5
M584 U1.0
M584 V1.1
M584 W1.2
M584 D2.0
M584 'j2.1
M584 'k2.2

M584 now reports:

Driver assignments: X0.0 Y0.1 Z0.2 (r)(c)A0.3 (r)(c)B0.4 (r)(c)C0.5 U1.0 V1.1 W1.2 (r)(c)D2.0 j2.1 k2.2, 12 axes visible

So the assignment appears to have worked exactly as it should. Does this work for you? There is a possibility that SBC mode might behave differently.

PS - in future, please post your config lines as text not as images, so that I can copy and paste them.

EDIT: I see that the reply from @chrishamm crossed with mine.

Thanks kindly both! Any target date for Beta 7? Cheers

@theolodian it should be within the next few days.

Bump for visibility.

Also, maybe related to this? Firmware installation issue?

https://forum.duet3d.com/topic/26435/toolboard-1-1-driver-not-present

dc42

@theolodian have you powered the system down and up again since upgrading the firmware to 3.4.0beta7?

If you send M409 K"boards" what response do you get?

theolodian

@dc42 Yes, I've tried several sequences of booting it up. I replied in the other thread. Thanks!

dc42

@theolodian thanks, the issue isn't the lowercase axis letters, it's that the main board hasn't received or hasn't processed the announcement from the 3HC. I'll close this thread.
