How do you make af work on nikon 3000, using a sigma 70-300 f4-5.6 dg macro lens?

Unfortunately, you don't. The D3000 does not have an autofocus motor; it relies on the the lens having one. This particular Sigma lens, unlike its Nikon equivalent, does not have a motor.

Nikon calls their lenses with an autofocus motor AF-S. Sigma calls theirs HSM.

The autofocus of my Sigma lens 18-200mm not working

You have just two choices then as it is not a DIY repair:-

1. Live with it until you decide to upgrade to a better lens;

2. Send it to Sigma for repair.

If you choose the second option, then if you're in the UK Sigma have a fixed price servicing menu, your repair would cost £93.99 on tariff no.6. Pretty cheap compared to a new lens, but expensive compared to just turning the focussing ring on an otherwise good lens.

The choice is yours...

I hope that you have found my answer to be of use, if so then please take a moment to rate it.

My Sigma 70-300 doesn't workin autoFocus mode. It

That lens is not an AFS type lens. The D40x camera only uses AFS compatible lenses. You could still mount and use it in M, but it will never give you autofocus or TTL flash.

Autofocus not working

If you don't know how to fix it yourself send it to Sigma UK (01707 329999). They are quite resonable charges for that sort of fault. Their website give a price guide depending on lens and fault. Steve

70-300DL Macro Super autofocus problem

It is likely that the lens will need parts. Sigma is not the best for repair parts. Typically, the small nylon gears that control the AF break. It is still a useful piece in manual focus. Repair costs would likely exceed its value.
