My first 4 axis milling on the #TravelCNC
the heigh and mounting of the 4th axis is going to be a problem.
The chucks hit the table when large objects are mounted using the mount that came with the machine.
The metal on the left is the original mounting.
The originak stepper has been replaced with a longneck with 5x as much force.
The new timing belt pulley is 3D printed and not yet perfect but it works for the time being.
I need to find a better way to clamp that wood.
It moved out of it’s chuck.
Depending on your output would a powered lathe point set work? One end free spins but the other has five in internal points of contact. See it on a Shop Smith lathe if it is not clear.
The entire surface is to be machined. The problem is rather fitting the diameter. The height of the Y gantry and the possible mounting heights of the 4th axis are very limiting.
In the long run I’ll have to modify the machine to have a higher Y gantry. But I didn’t machine aluminum yet (on the larger machine of cause)
