80x80x3 or better 100x100x3mm will greatly simplify the structure and the welding as no diagonals will be needed. 50x50mm is weak for such purpose.
Gantry could be welded from 2x 100x100x3 or thicker welded together or a distance for screw in between. gantry legs can be 2- 3 pieces of 100x100 welded together. Check my build 2. If you are not into welding, painting and so on, better make the gantry L style like Dean/ JAZZ CNC / makes his machines, from aluminum. it will greatly simplify it, though a bit more expensive.
Box section comes on 6m pieces here ion Spain
I know you would like a small machine but if you make it beefy it would make a lot of difference when machining aluminum, especially on the finish and precisionLast edited by Boyan Silyavski; 08-04-2020 at 08:25 AM.
