Thanks Neale, i'm definitely still feeling my way with the machine and software etc for that matter. Didn't alter much g code wise from what fusion 360 CAM spat out. Other than adding G91.1 and G54 commands because it just wouldn't work from the original post process. I certainly need to learn more about feeds and speeds to improve on efficiency. Each one of these cuts took 8 minutes but it felt much longer chasing the cutter around with an old dyson. I need to get a little more organised!
