Mini Mill Control Board

Hi VC,
I have found this wiring diagram but it may not be exactly the same as yours. How did you get on finding a replacement pulse transformer ?

Les.

The terminals marked A- and A+ go to the motor, P1,P2 and P3 go to the speed pot, L1 and L2 is the 240v ac input.

The P terminals, 2 is the pot wiper( middle tag) 1 is the left tag looking from the knob end, 3 is the remaining tag...

This info relates to the KB board or the chinese equivalent, NOT the Sieg boards.

Depending on whose mini mill it is, there may be another seperate board with a relay and some passive components. The AC and motor wiring goes via this board....

Thanks Les have seen that diagram but does not turn a light on for me my neighbour is a hottie on electronics so he has repaired the board so don't want to let the smoke out

and thanks to John but once again not making any sense to me

What I need and would like if someone has the same X1 mill where all the wires go

board has gnd know what wires to put there L1 and L2 not sure about these two the "pot" has a a three plug so thats sorted two other wires with k1 and k2 so ok there two wires left on switch 4 and 8 too A+ and A- so thats ok

now just left with brown and blue 6 of the little buggers 2 from the mains and 4 from the EMI Filter

Thanks for the replys

Hi VC,
You will need to say whose version of the mini mill you have before anyone knows if they have the same one as you. Failing that I would start as John suggested and connect the wires that are easy to identify. If your mill has a reversing switch then the wires from the motor will connect to that then two wires from the reversing switch will connect to A+ and A- (It will not do any harm if they are the wrong way round. The forward and reverse positions will just be transposed.) Some pictures of the wiring would help. If you put some markers on the end of the wires that would be a great help so we can say something like connect wire "A" to terminal. This will be easier than trying to describe which wire we are talking about.

Les.
