| 01/31/2008 - Added Y and Z axis limit sitches and limit switch adjustment screws. | |
| 01/30/2008 - Cut out the corner gussets - added X axis limit switches | |
| 01/29/2008 - Added Y axis upright bracing. Made long motor mount screws. Drilled holes all over the frame to mount the top to. Made the X axis bearing block of oak for now until I can come up with a better design. | |
| 01/16/2008 - I cut the bottom piece that connects the two Y axis uprights. The X axis screw block/Delrin bearings holder will connect to this piece. Note that I can go to twin screws in the future if I want to. I still have to add some corners gussets and cross bracing to the frame before I have it all welded solid. I plan on adding some 1" Angle aluminum pieces to the Y axis uprights to give them more side to side rigidity. | |

| Limit switches - I drilled and tapped small 4/40 adjustment screws where the tip of the limit switches contacts the sliding platform on the actuators. I can move the screw heads in and out to adjust the limit switch contact points. The 4/40 screws have nuts on them so I can lock the screw position. The picture on the left above does not have the screw in the hole yet. You can see one of the screw heads in the large actuator photo above on the right. | |
