3ph?
The board has BLDC on it ?
Is this a PM field motor?
What is the application for the fixed speed?
What is the motor data plate show?

On the right side of your pic is a yellow and red wire. Can you move the yellow wire and take a pic of what it says under?
my cnc is general cnc 40-915These motor appear to have also been used in the low end CNC market, How come the spindle has been set at a fixed speed?

I suspect the 3 pads on the PCB at right are either for connection of a speed pot or hi/med/lo digital inputs, which are bypassed by the red and yellow wires for constant hi speed. There is also a spot for what I suspect to be a trim pot beside these pads ("ADJ2") which has a fixed resistor soldered in place.These motor appear to have also been used in the low end CNC market, How come the spindle has been set at a fixed speed?

no the s command dont work its just 21000 rpm probably because its a wood router but i want cut aluminium and for that i need to reduce rpm and i dont think the support show me how hack this board@steevens does the table manuf. have a support line?

If you're on board with the idea of stomping the board to pieces (which you absolutely should be, in my humble opinion) then you have nothing to lose. Why not try desoldering the red wire from the "H" pad and resoldering it to the "L" pad? It might fry your board or it might do exactly what you want. I make no guarantees.no the s command dont work its just 21000 rpm probably because its a wood router but i want cut aluminium and for that i need to reduce rpm and i dont think the support show me how hack this board
i am not good in electronic, but i like test lolI suspect the 3 pads on the PCB at right are either for connection of a speed pot or hi/med/lo digital inputs, which are bypassed by the red and yellow wires for constant hi speed.
