I was thinking about powering the gantry and the rest of the machine via rack and pinion. The rack will be mounted on the top of the gantry. So from the verticle Ali plate will be a piece of Ali coming off at 90 degrees, to accommodate the motor and possible rack and pinion drive. I will attach a picture of the gantry as it is now.... Please note that the machine is still in raw state simply until I get her performing how I would like her to. Also the 25mm X axis is also temp so I can cut parts as I need them to upgrade
