Hi Tom

If I was to build another I would change a few things

Not sure what the unsupported rails is in reference to ?

regards Steve

Hi Steve
You have nice Hivin rail on X and Y axis and round rails on Z which are supported at each end. Those rails can be supported like in the my picture or free like in your case.



Yes its true, every time you build new machine is better and better, question is where is the end?
Just spend one day revising my latest project because somebody point me on overhanging issue of my spindle in relation to the gantry. I managed save only ~50mm of that distance but with price of complicating design.
It was wright approach as I probably would regret if I kept like was.
Your work is good - clean and nice, wish you happy new year
Tom
