Z Stepper won't run

The board is 3 axis Blue Board. The only id is "30695S" I have attached a picture.

Here is how I configured the board via Stepconf.
Pin:
1 X Step
2 Y Enable
3 Y Direction
4 Z Direction
5 Z Step
6 Amp Enable
7 X Dirction
8 Y Step
9 Spindle Motor
10 Input 0
11 Input 1
12 Input 2
13 Input 3
14 X Enable
15 Unused
16 Out 1
17 Out 2

This config allows X and Y axis to work both in Stepconf and Axis. When I try Z in Stepconf the only that happens is that the motors on X and Y are buzzing (shaking) but the Z motor does not. Nothing else moves when testing Z.

btw I changed the motors around and they all work if used in X or Y.

try a new config with the following

pin2 xstep
pin3 xdir
pin4 ystep
pin5 ydir
pin6 zstep
pin7 zdir

just in case
it's trying a few combinations that we know were used on these boards

I will try those, but what about the other pins. Should I config them as unused? Or should I set those up by hand?

pin2 xstep
pin3 xdir
pin4 ystep
pin5 ydir
pin6 zstep
pin7 zdir

No good. Nothing works.

It might be worth tracing the actual tracks on the PCB to the stepper driver chips.

I have been reading some other threads and notice that the "amplifier enable" might have a lot to do with this situation. I am beginning to think that since there is only the amplifier enable switch that doesn't appear to be tied to any specific channel that maybe "amp enable" needs to change state before moving from one axis to another. I don't know if that makes any sense.
This all leads me to believe that the answer will lie somewhere in HAL config. If thats the case I think I'll need a year or two to learn that language before I'm able to do anything with it.

In the meantime I will try ringing out the leads and see what I can discover

Tks again
