El Beast - Initial design phase, comments and critique welcomed!

Just out of interest, 50x100 GFS (high rigidity version, 6.8kg/m) milled profile works out to around £70 per metre before tax.

Given I only need 2 metres of it that's not too bad really for a milled mounting surface I think... might be the way forward.

Why do you think it would it be more rigid?





Personally I think the machine as a whole will be more rigid with the current setup as it allows me to bolt the frame and frame supports to the tool bed for added frame rigidity while keeping the unsupported gantry arm to the minimum length. If I flip the supports 90 degrees and set them up like my current machine then I have an unsupported bed that will flex, and I can't put the cross supports in as they would then interfere with the ball screws... unless I underslung them which would be a mounting nightmare.

Yes, it would be. But there is the challenge to align all.

The only way to align that easy and properly 100% is to rest all frame on flat surface and lift rails on paralel blocks same size and then tighten. But i assume you dont have that flat surface. So you may have to think of sth else. What i am saying here is that a design is as good as you know all steps, to finishthe machine. To figure the details meanwhile you are building it=wasted money and time
