The rails are supported, and you'll get some idea of the machine from the picture (I don't need any comments on poor image quality or poor workshop order, and won't give you any lame excuses for it either)
Also a picture of the workpiece, for reference the pocket is about 12mm in diameter.
Wizard: Im not really clear on what you mean by "Also is the final pocket over sized", could just be me not familiar with cnc terminology. could you clearify please?
I'm now in the process of redesigning the machine, with a lower and a lot stiffer/stronger gantry. Along with longer distance between the linear bearings in each pair, to relieve stress/bending of the rails.
Would that be a proper first step in your opinion? Although as Wizard pointed out, this machine may never be suitable for cutting aluminium.
Thanks a lot for all the answers so far!
