If soft materials plastics,softwoods etc then the high sides won't be a problem
you wouldn't believe me, but I was almost sure that I will be able to cut hardwood and do light aluminum work (now you can laugh of me)

Ok., I think I know what you both trying to say for me..,
so now in my head I have new CNC table plan ( I hope it will cut at least hardwood ).
Version_2 will be here soon

Thanks guys for the advice!
