Using the 10th Stepper (D axis?)

TechnomadicJim

Hi Duet / All

Thanks for creating such a great board. I'm really enjoying using it although I have one issue I can't seem to find an answer for on the forums or in the docs:

I want to use all 10 stepper drivers on my Duet Ethernet + DueX5 as axes for a CNC project. I can get the first 9 to work fine (X Y Z U V W A B C) but I can't get the 10th (drive mapping 9, axis D) to appear or work. Here's my config:

@TechnomadicJim see https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping

U, V, W, A, B, Cnnn Driver number(s) for additional axes U, V, W, A, B and C (UVW available in RepRapFirmware 1.16 and later; UVWABC available in RepRapFirmware 1.19 and later; UVWABCD available in RepRapFirmware 3.0 and later)

No D in RRF2. You’re going to have to update to RRF3. But that’s okay, it’s the future!

Thanks for your reply Ian. I've upgraded to 3.01-RC3 (I also tried the non RC stable version) but I'm still unable to access the D axis. Is my config.g correct? I'm not sure what else to try.

@TechnomadicJim can you post your new config.g for RRF3?

Ian

If you send M584 without parameters, does the response mention the D axis? Likewise if you send M92 without parameters.

The maximum number of axis on Duet 2 is currently 9. I can increase it to 10 in release 3.01RC4.

It doesn't although it does mention "E3" which is odd.
Driver assignments: X0 Y1 Z2 U3 V4 W5 A6 B7 C8 E3, 9 axes visible

Ahh ok thanks. So I'm not going mad and it's a software limitation? Looking forward to testing RC4

TechnomadicJim

I just upgraded to 3.01RC4 and I can now use the D axis.

Thanks @dc42 for the quick fix. Much appreciated. Also thanks @droftarts for your help too.
