This is the second design of the bracket to hold the stepper motors for the raising mechanism. Rather than dangle off the legs, they are now supported from underneath with a triangular bracket. This not only strengthens the support for the motors, but helps the motor sit upright and also adds a bit of strength to the table.

They might be a bit over-engineered at the moment, but they will work for testing.

The sockets for the threaded rods now go into a rubber mount. Not fully convinced yet. Initial testing showed there wasn't enough current to go to all 4 motors at the same time, so I will revert back to having 1 motor driver board for each motor. This will need a little bit more wiring as I can no longer daisy-chain the motors.
