Hi @chrishamm
today I got the following error while porting the gcode meta command printjob into an macro.

echo >{"0:/filaments/PETG-1.0-coldfusion/config-auto-nle-1.g"} "test"
Error: expected an expression

the same code is working in standalone mode and was working in the job processor.

just to make sure, the following will also fail

I don't know if this is already fixed upstream, as I'm on the +6 dev version. But I was not able to find any related commit so maybe worth it posting it here.

btw. since I swapped the rock pi 4c+ with an rpi 4b and running the +6 dev build, the unit is printing rock solid!

@timschneider I just tried to reproduce this problem but it works as expected here, both from DWC and from a macro file. It's possible that one of my latest commits had an effect on this problem, although to be fair I wasn't aware of it before. And good to hear your machine is now working well apart from this issue!

@chrishamm ok, thanks! I've updated the printer to dev +8 and it is indeed fixed!
