With A-axis you meant Z-axis, right?
I don't really get the thing you said regarding the bracket, so I can't give you my opinion, I'm sorry..
I know controllers have a pot to change output current flow, and that's indeed my problem: the a4988s I have do not reach enough current even at their max. That's the reason I want to change them. Actually, the only one causing me some head scratch is the one on the Y-axis, that causes the motor to make a lot of noise and vibrations, but maybe with better power even the other motors will work better.
Finally, I'll definitely add cable chains even if they can be a pain: I don't really like having wires all around the printer!

Sorry @SteveRoy, maybe I wasn't clear: I meant the springs on bed bolts...
You attached two pics about them: one with springs and one with what seems to be a 3D-printed spacer.. What is the difference? I thought springs were good to separate the heatbed frame mount (the x-shaped one, to be clear) and the PCB heatbed itself, so why using that?

The bed doesn't need a spring for adjustment at the home position, this is done with the long nylon nut off the X motor mount.

The spring is there to allow the bed to eventually move down during the Z homing to trigger a frame mounted Z switch and avoid head crash, Z motor stalling etc.... For ex: in case of a thick plastic blob on the nozzle ....
It is not necessary if one use the nozzle contacting the bed to set the Z home (switch, piezo, strain gauge .....) or proximity sensor.
