Hello Folks,

sorry if this question has been discussed before, if so, i couldnt find it :)

I am currently thinking out my Design and I am not sure how to make the X Axis.

Either the whole Gantry slides, or the Gantry is fixed and the "Baseplate" slides (lack of the right english word, sry) ?

I will probably use 600mm TBR20 supported round rails for x and y, so thats what the size will be.

Anybody has empiric experience comparing the two methods ?

I want to design the gantry it self as per the paper posted in the faqs, problems, solutions forum regarding "heavy duty design".
I mean just the structural design, not the materials used.

Built from 40x40 Alu Profiles triangular reinforced, i already drew it that way but of course I forgot to make a screenshot :)

I personally prefer the "fixed gantry and sliding baseplate" design, that way I can make a really sturdy gantry.

Another slightly off topic question, that just popped in my head, would be how to fix the TBR20 Rails to the profiles, I dont know if I like the idea of just bolting them down with T Nuts, otherwise I would have to make adapter plates, which in turn would add some of the much desired mass to the system.

THanks in advance,

Regards,

Clemens
