I have had the mill for some time but I have only recently started using it for some projects.
One of the frustrations - possible myself being slighty short in height was the Z Axis adjustment. Using inspiration from this site and having acquired a single phase induction motor with mounting bracket, speed controller, gear and chain from a Nutek PCB Conveyor I decided to adapt it as a Z drive for my mill.
The only purchased items was a plastic enclosure (to mount the controller, additional on-off switch and the direction selector switch) and a second 06B gear to suit the chain. All other electrical items I have acquired over the years from my work.
The 06B gear was bored out to the correct shaft size, a 4mm keyway slot added and three M4 tapped holes around the body for grub screws.
I wanted to retain the original handle for manual adjustment and made the handle adapter to fit / centralise on the gear. The start of the thread was initally damaged by a poor die.
Two limit switches and actuator block were fitted to the machine to stop the drive at each end of the machine stroke.
Parts Used:
The system work great as long as you dont start off in a very low speed.
The motor must be stopped before changing the direction.
