Run macro that does:
-G10 L20 P2 X0 Y0 Z0
-G55

Alternatively, use P1 in the G10 command instead of P2, then you don't need the G55.

This is true... but... a lot of people like to leave G54 matching machine, because there the controller is always in some Work Coordinate System, and it just makes more sense for the human to have G54 match the physical layout of the device, G55 match the first fixture, G56 the second fixture and so forth.

Again, there is no "right or wrong" here... and some people do it a completely different way... the most common practice I've seen is leaving G54 alone (or, technically, G54 has a 0,0,0 offset to G53).

To be fair, I'd already realised it was an rpi image and I'd need to reformat it, I just had no idea which type it needed to be. Even a sticker on the bag it comes in would be a bonus for newbies like me lol

@Phaedrux
Thats a good point, I will do that

It is possible to tell RRF a transformation matrix (M669), so transforming the machine coordinate system to match the workpiece could be done with some conditional G code. I think you would need variables though, and those are not supported yet.

I've submitted a small fix to the Cura devs that stops the small line segments being created when you have curved walls lying immediately adjacent to each other and the overlap compensation is enabled. It should fix the project discussed above but doesn't really tackle the underlying problems that the overlap compensation has. Fixes are currently taking many months to get merged into Cura (assuming it is accepted) so don't expect the official releases to have this anytime soon. The next development version that I release will have this fix in it. See https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

That seems to have worked! Thanks!
