Initial design advise wanted

[driftspin]

Yes but is that the design with the extra bracing you want to put on?

Clive eh no, the initial gantry design is 65 KG with no extra bracing (80x120x4). The profile used is 940mm between the linear blocks.




The profiles on the gantrysides will have inserts so the m5 bolts can still be reached but sides ways flex is stopped.

Maybe i need to brace the Z slide on the sides ... aluminum can be flexi i heard.


What i am thinking about is maybe step up the gantrybeam to 120x100(or120x120)x5mm .... the linear rail wil be mounted close to the edge of the profile, for maximum stifness.
It will also generate some extra space for cable management, i have to look in to that too for the long axis also.








Some diagonals in the legs. maybe panel icw kabinets.. to be determined.
Filling the Highlighted parts with sand may do some good anti vibration and ringing?
