I have updated the design to include steppers and all mounting holes, ive taken on your advice and beefed up the extrusions so they no longer need additional reinforcements.
all structural joints are done by brackets
all holes 4mm holes are used for fastening (rivets/screws)
10mm holes for limit switches
and the and the dril rod floats in the air like that because i tell it to, you gotta show it whos boss. |
