Hey guys.
After owning my mill motor for well over a year & still sitting in the box, I thought it might be time to wire it up. I've followed a few examples on the net but I can't seem to get power from the power supply to the mill motor.
Could someone drop some photos in here describing what wire goes where. I've wired up the 240V side so the power supply powers up, the red motor wire in top port of green pcb board, black motor wire to the bottom of the pcb board but I'm stuck there.
I've got this power supply,

Can you post an actual photo of your motor and wiring?

Are you having trouble with the power supply side or motor side wiring?

I found this... might be what you are looking for.



From what i can gather, pink line is positive and green is negative.

I looked at that but my PSU is different.
From the left of mine, I have +V for three ports, -V for the next three ports then E,N,L. I would assume one wire goes to the +V & the other to the-V but not too sure where those wires then go on the green pcb board. I've got it wired different to above so I might do what is done there. I'll give it a go.
Cheers

Can someone that's wired up their Motion Dynamics mill motor show me what wires they put where from the variable speed pot to the little green board. I've tried wiring it up in so many configurations but the motor just runs flat out, no speed control at all. I'm starting to think I have a faulty board.

Don't know if you have already looked at this Crusty
Thanks for that. That's the package I have.
I just can't seem to get the speed control to work. The potentiometer is fine, I've measured resistance with a volt meter & it works but when I wire it up to the PC board, nothing, no matter in which configuration I wire it.

Give them a ring tomorrow
Will do but there's shit loads of people on here that have wired them up & was hoping to get some insight. I'm stumped with what's going on. It's wired correctly as far as I can tell & I'm a bit suspicious that my board is cactus.

Best way to look for old threads is through Google. I was going to suggest Jaycar if there was one near you, but they will be in lockdown the guys there a pretty helpful.
Just Google motion dynamics Aussie Home Brewer, tried to link it but it didn't work.

Have you got it on the right jumper settings?



According to this, you need it on J1 2-3 for the potentiometer.

I'm not sure. I have it wired to the same three ports as in the picture.
The bottom three ports on the left. The motor works fine just no speed control.

Do I need to have a switch inline to possibly power the pot? Maybe that's the problem. If I don't wire a switch in, can I just use a jumper lead into the top block?
Where my thumb is, out the top & in the bottom of the same block, the very top one.

On the right hand side, numbering the terminals from 1-8 top down.
In the drawing they have a jumper from 1-2 and 7-8, I cant see the same on your board, it might be that the control isn't being powered.
Mind you I'm OK with wiring power but electronics isn't really my thing.

Thanks Mark.
It's so bloody confusing. This came with it as the instructions, different again. I don't think you need the jumper wires for 30A, according to instructions it's for 50A as ports 1,2 are the same, 3,4 are the same etc.

I ran a jumper lead into that first terminal block & a green light activates so there's power but still no bloody speed control.

I even tried soldering the pot.
