Is this AxiDraw v3? Have you gotten any commands to work?

[nestcodehouse]

Yes , it is AxiDraw3 , only when I issued "axi on" I heard some noise from the AxiDraw , Any command that involves movement failing with this error

[fogleman]

@oskay any ideas? My code only sends QS but this error says !8 Err: Unknown command 'QS:5153'

[oskay]

Outdated firmware?

[oskay]

The QS command was only added in 2.4.3 (very recent) and isn't used in any of the software that we're publishing.

[nestcodehouse]

so is it recommended to update the firmware to fix this issue or remove the usage of QS from the axi python module ?

[fogleman]

@oskay Did any AxiDraw v3's ship with older firmware? @nestcodehouse Did you change the firmware on your device?

[nestcodehouse]

No , I am using the firmware it came with

[fogleman]

I'm suspicious of the ":5153" part, but I have no idea where that would be coming from.

[oskay]

Try running the firmware update, and see if that helps.

I had the same issue using an Axidraw V2. Updating the firmware fixed it for me.
