prusa auto focus laser

prusa based x axis, use full length smoothrod maybe a bit less so the 3 foot thread rod can be used as tube support.

40 watt laser tube is 29 inches in length so there is plenty of room to mirror it around and send it to laser head.

just a start, this is a WIP still.

probably going to redesign for #10 ballchain instead of belt
