I wasn’t able to screw the motor on in any good way, so I just went for zip ties. Same piece of rubber hose for the motor coupler as on the Y-axis. The linear Actuator is the same 3/8″ threaded rod as on the Y-axis. The 3/16″ metal rod above the actuator is there to stabilize the laser carrier.
By the way, This is really starting to look to me like a legit CNC machine.
As for the structure, I just have to make the laser carrier and connect the electronics. Then it’s on to the software side.
