Help with speeds/feeds please?

Thanks Paulus, I will try that.
Anyone got any advice on the aluminium parameters please? I understand that there are many variables that effect this but am just confirming figures roughly so that I dont snap the 2mm end mill within first 5 mins of cutting. Thanks.

Nobody can answer that question correctly because you don't give enough detail.
Even then with such small tools it can be lottery and you'll need to adjust on the fly while cutting. Coolant and good Chip clearing is MUST.

Honestly knowing you have only just got your machine working I think your being a little too ambitious trying to cut aluminium with small tool without any experience of machine or material.!! . . . Expect to break lots of tools.

Cheers Dean, after doing the first cuts yesterday it did sort of click that I was trying to run before I could walk For others, this is what 'cooked by end mill' MDF looks like

It was just so tempting as I had the material and tools all at hand so thought why not

The tools and details I am using are the following, all cheap eBay 2 flute cutters, aluminium grade either 5083 or 6082 as I could get either:
Cutting Pocket 1mm depth 40mm diameter - 6mm ball nose (50mm total length, Carbide tool, 20mm stick out)
Finishing 3D relief (1mm overall depth) after roughing with the 6mm ball nose - 2mm ball nose (50mm total length. Carbide tool, 14mm stick out)
VCarving text at depth of 0.35mm - 6mm 90 deg Spot Drill (67mm total length, HSS tool, 20mm stick out)
Profile part at 5mm depth - 8mm End Mill (61mm total length, HSS tool TiN Coated, 30mm stick out)

All tools got hot but the final profiling end mill was the one that got REALLY hot. Getting air connected will be easy enough as pipe, parts & 3 nozzles at spindle are setup but think I might have to start work on the mist setup sooner rather than later. Could I get away with air blast with manual spray of WD40 for now with smaller runs? Thanks.
