Requesting some feedback on steel frame design.

[Misc]

Thank you for the feedback, the design has been redone from scratch. I have decided how the gantry should be mounted, but not how the gantry itself should be built. A slim gantry is not easy to design (if at all possible) while also being inflexible.


I am planning on adding a center tube to support the middle of the bed in the front.





The bed is supported by 3 tubes of 50x50x3 tube in the middle section, the sides rest on a 5mm thick piece of angle iron.





Steel tube sizes are as follows

• Green: 50x50x3mm
• Yellow: 80x30x3mm
• Pinkish: 70x70x3mm
• Plates: 10mm Aluminium on the carriages, not sure if i should switch to steel?

At the moment the gantry has 500mm travel are the linear carriages are spaced so they are 230mm end to end, I read later that these should be a minimum of 250mm. So maybe i should widen the gap?

As you can see the wall thickness is 3mm all around, I am considering 4mm to make it stronger; But it is already quite heavy, so is there any parts that will benefit more than others from extra wall thickness?
