Hey everyone
I had this bug in my head for a while - i want to build a large cnc at home (1.5 by 1.5 meters) on the budget
Mainly to cut mdf panels but also sometimes aluminium and to try cut steel

I have seen on the internet some people actualy made some machines like that but there was no information one the accuracy of cut and rigidity

Sadly i cant find aluminium profiles in my area so i was thinking about steel square profile

Im alittle afraide the gantery can bend abit at such length
Do you think i can get 0.1mm or less accuracy (due to bend only) of cut, cutting mdf and 80x80x2 steel gantery?
