Hi all, hope everyone is having a great December. Owned a Chinese 6040 with 1.5k spindle for a couple of month. Loving it - even though there is a little screech on the far-end of the y-axis

I've been making LED stands for acrylic engravings - mainly out of HDPE. Unfortunately, that stuff takes a lot of burning, sanding and polishing to get decent finish. So I'm looking for cheap materials to use that don't need as much work. I've made a few designs using a mix of aluminium, black acrylic and brass spacers. I'm also considering aluminium composite. Thing is I've not tried cutting any metals yet and I don't to rush straight in without getting any advice off you guys first.

What ER11 would you recommend for cutting aluminium - and aluminium composite. And what feeds, speeds, stepover, etc, would you recommend?

Thanks.
