My Cheapo Chineese 3020t mini CNC Build (more like improvements) leanring all the way

I just dont know how to supply power from the enclosure box to the large silver power pack which is mounted on top for the spindle.

It has these connections on it:

Hi there, could you explain a bit more what you mean when you say power pack on top for the spindle?

The photo you have there is a typical Chinese power supply, it will need to be wired to 230v AC - Mains.

I don't understand the question. You connect the mains to the L and N, the Earth to the one beside N and the spindle to the + (normally red wire) and the - (normally black or blue wire). If you have a regulator to adjust RPM then you connect that in between the power supply + and - and the motor + and - terminals. The PWM module should have some kind of documentation describing this, or printed on the PC board there should be clear markings.

hi mate, basically I have wired the small pcb that came with the spindle to the controller from planet cnc. However I dont know how to supply power to the silver power pack which is for the spindle. Been trying to get documentation for the spindle stuff but the ebay seller is not playing ball at the mo

hello alex,
sorry didnt see your reply, yes thats the box im trying to supply power to, but not sure how to tap of the power going to the controller box

Hi Ravi,

You need to connect that Power Supply you have to 230v AC - Mains Voltage.

Looking at the PSU you have the far right three terminals: Earth, Live, Neutral.

Get a common Kettle Plug (For a PC or a PC Monitor etc), cut end off and use it to power the PSU.

USUALLY - in a typical plug it is as follows:

Blue - Neutral
Brown - Live
Green / Yellow - Earth

If you want to be neat about it then you can get one of these: Click Me

That will you mean you can just plug it in and have it modular.

Once you have the PSU live, you just need to (I assume - I do not know what you have been supplied to control the spindle), power the PCB using 48v DC from the PSU using any of the remaining terminals. You have 3 sets of -V & +V on the left hand side of the PSU.

I'm really tired today just travelled 1500 miles but looking at it Earth, live & neutral to the mains and you have 3 positive rails and 3 negative rails for the DC out.

e2a alex beat me to it with a better explanation lol do what he said.

Thank you very much lads for the help, so on the back of the bottom enclosure box I have 3 pins which a kettle like cable plug into:


This currently is plugged into the power supply box for my controller, can I just taop into these 3 pins and then wire some more wires to the spindle controller l, n and gnd?

I imagine that would be fine, can't see it drawing more Amps than that plug is designed for.
