Compared to a desktop gantry mill.
Gantry ought to be more stiff.
That depends on the gantry, my

Yes;
a curiosity: when the cobots press the freedrive button, they use
torque sensors such as ? on an admittance based control or just add

One of the continuing discussions on the Gingery "Make your own shop from
scrap" forums were the lightness of aluminum castings and how that made them

Epoxy is a bonding agent
Fiber (glass or otherwise) add cross linking in the resulting matrix.
Thes two Used alone, the resulting composite will be weak.
You need sized aggregate to make a much more rigid and robust structure.
The epoxy is then strongest bonding all these parts together
