Hello from London

[JAZZCNC]

Thanks for the suggestion JAZZCNC, I didn't show the X axis well enough, it's two pieces of box steel that should help with resonance? Also definitely planning on adding some bracing

The design as you show it isn't strong enough for a gantry and it will flex/resonate. 50mm box section with 3mm wall is like spaghetti so you will really need to brace it good with nice high up triangulation.
