03-04-2014 #1I want to ask then why many people try to build the gantries with aluminum that it is lighter than steel and also more expensive.
Why many people try to make their gantries as light as possible without of course having compromises with stiffness.
Finally why nearly every Z axis is made from aluminum and not from steel.
The Z axis is one place where lighter weight is helpful. But I think ease of fabrication is still the main reason aluminum is used.Gerry
