Did a bit of machining today. Machined 2 x countersunk holes to suit M8 bolts on the Z axis back plate to take the Y axis ballnut bracket.
The Y axis ballscrew will fix straight onto the back of the gantry so won't need shimming.
Scratched my head a bit today trying to work out how to mount the Y axis stepper motor so I can adjust it to tension the belt. In the end I've decided to put the pulley on the rear of the stepper and mount the stepper on the front via a bracket...
I'm hoping that as the only tension on the stepper is from the belt that this arrangement will do?Last edited by njhussey; 09-03-2015 at 06:42 PM.
