Have you tried to use a speeds and feeds calculator?
I think that cuts like 8mm depth of cut 4mm width of cut at 3500mm/min feed at ~20.000rpm is wrong, too deep and too fast.
Drilling aluminum at 6000rpm with a 5mm drill is OK but you need to have a pretty low Z feed rate and you must peck drill, using a drill bit, not a cutter.
I think that cuts like 0.5mm depth of cut 8mm width of cut 4000mm/min feed ~7000rpm is wrong because of low rpm and high feed rate. I would increase the rpm.
What sort of cutters are you using?
How about reading the manual...? I mean, seriously, these are very basic basic questions, pretty well documented and you should REALLY study those 25 pages before asking to be spoon fed... In the long run, YOU are the winner if you read the documentation delivered. Sorry if this sounds arrogant, but laziness is not a virtue. While many times we can blame the Chinese for poor documentation, in this case it is definitely not true.
Never the less, here is my answer.
Your config is already set up for the relay, as I would like it, so no change is necessary there. Screw terminals 14, 15 and 16 are the relay contacts, as stated on page 11. Page 5 shows the relay and tells you that:
Lk = 14 = normally open
Lb = 15 = normally closed
Lz = 16 = common
You need to use screw terminals 15 and 16 if your e-stop circuit uses normally closed circuit, connect the relay in series. If you are using normally open circuit then you need to connect 14 and 16 in parallel with your e-stop circuit. This is not a good design, normally closed design is better and safer.
Anyway, now I close your manual and you should open it and read it because it is YOUR manual and it gives answers to all your questions except the feeds and speeds.
