Hi,

I needed a way to use use the offset command OFF J and make linear moves (plunge straight down). I couldn't find a way to do this with what the AR4 v4.4 currently offers, so I implemented a OFF L command, which does what it says in the name: it offsets from a register position linearly. I didn't actually write anything new here, the command is just the OFF J and MOVE L commands mashed together.

If you want to use this yourself, using the AR4 Mk4 control software source, use this patch file to add it to your own version. Apply with `git apply LinearOffset_AR4-v4.4patch.txt`

Would be nice to see something like this implemented in the official version (though it's not out of the question there's a way to do this already and I'm being a massive fool :)). I can't be the only one who could make use of something like this. Thanks!
