Referencing single-quote axes

drivetrainsystems

I see that duet3d supports axes past D now which is vital to my application. However, I am having trouble referencing these axes. For instance:

G0 'a100

does not affect the 'a axis but rather the A axis.
Am I using the correct syntax?
I am using a Duet3d Mini5+ and firmware 2.5.1

The config tool will let me create configurations for lower-case axes such as 'a. But the home files it creates affect the A axis. For instance, the line

G1 H1 'a-155 F1000 ; coarse home

does not power the 'a axis but rather the A axis. This appears to be the case with all G-Code commands; commands for single-quote axis do not affect the single-quote axis, but rather the capital-letter access.

@drivetrainsystems I've merged these topics as they are essentially the same.

I am using a Duet3d Mini5+ and firmware 2.5.1

Do you mean 3.5.1? If so, please update to 3.5.4 and test again. https://github.com/Duet3D/RepRapFirmware/releases/tag/3.5.4

How many axes do you have defined? The maximum number of supported axes is 10 (not including extruder drives) on a Mini 5+, if it is being used as the mainboard. See https://docs.duet3d.com/User_manual/RepRapFirmware/RepRapFirmware_overview#firmware-configuration-limits

Please post your config.g file as well.

@droftarts sorry, yes I meant 3.5.1.
I will update to 3.5.4.
I have 16 axes total, using 3 Mini5+ boards connected via CAN.

My config.g config.g

Update: initial tests on 3.5.4 look like the issue is resolved! Thanks.

@drivetrainsystems Great, glad this is resolved for you. Though I can't see anything in the release notes https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x that specifically addresses this issue.

@drivetrainsystems are you running with attached single board computer? I think there was a problem in early 3.5.x versions of DSF when lowercase axis names were used.

drivetrainsystems

@dc42 no, I am controlling via USB from a laptop. I am using DWC for diagnostics, and it is hampering that DWC and RepRap config tool only allow limited number of axes. Also, RepRap config tool does not supply the latest firmware.

I have at least three symbols on my keyboard looking similar:

'  ` ´

Just wondering if it was a typo error? But then the FW upgrade seems to work, maybe it's more typo-tolerant ?
