This crops up quite often, so I hope this helps some people who’ve asked about speeding up their work.
We all know engraving takes time, this is because the head has to move back and forth for every line (specified in your Lines Per Inch setting), but there’s also “overshoot”, the extra distance needed for the head to slow, turn around, and speed up again.
If you need to produce multiple copies of your design, you can easily copy and paste, and line them up to make best use of your material. The problem here is that each copy will be treated as a single piece, so the engrave will run once per copied piece, like so:
The issue here is that the movement of the head at each end of the pass can take as long, if not longer, than the time it’s spending actually engraving the material. With the latest speed improvements, that extra time can be significant.
The solution is to combine multiple copies of the engrave portion of your design into a single large component. This means it will be processed as one element, drastically reducing the amount of time to print:
