When installing a glass bed, what do you change? I have an Anet A8 clone printer with a heated aluminum print bed. I'm considering purchasing a glass bed to add on top of the aluminum. When adding a glass bed on top:


How would I go about installing the glass onto the aluminum bed? Is the major concern here just affixing it?
How do you adjust for the added thickness of the bed in the printer? Is this just through a limit switch adjustment or something firmware/software related?
How much do you adjust your heat (if at all)? Does it take a longer warm-up time due to having to heat the glass?
The most common way to install a glass bed (assuming it's literally a piece of borosilicate glass) is with binder clips. Glass is an insulator, so you may need to adjust your bed temps by a few degrees, and it will take somewhat longer to warm up.

You shouldn't need any firmware changes, but will need to adjust whatever z homing you do. If you have a limit switch currently, you'll need to move it by the thickness of the glass. If you have an inductive probe, it should still continue to work, but your z-offset will need to be adjusted. If you have BLTouch or a piezo, nothing should need to change there.
