SVG CLI error: object of type 'LaserOperation' has no len()

Trying to use the command line options to parse and execute a job:

meerk40t -zaS 100 ~/circle.svg

I get the following error:

I figured it out! I just ended up deleting the actual operations, since deleting the elements didn’t really work.

Here’s the final command line:

meerk40t -z -e “timer 1 1 home” -e “inkscape locate input 304705.svg text2path load” -e “element* translate 0 0” -e “element* translate 3in 3in” -e “timer 1 2 operation2,3 delete” -e “timer 1 3 elements* engrave -s 110” -e “timer 1 10 plan copy preprocess validate list append home blob list spool” -e “timer 1 50 quit”

Sorry for the delay.

I guess maybe delete the other elements. I’ll track down the reason this is happening and make those commands a bit more robust since I couldn’t use them to see if it was working weirdly.

element1,2,4,5,7 delete will get rid of them from the list. Then they certainly can’t end up engraving.

The menus do exist in Mac OS X. They conform to Mac OS standards instead though; and appear in the regular menu bar at the top of the screen; next to the Apple menu, and MeerK40t menu. They are only active when the Jobs window is in front.

The Camera window will also override menus to show those are specific to the camera window as well.
