There is no black and white, only gray :D
Ha! very true!

Your design is very similar to one I started to draw up, with the deep sides to avoid the bendy gantry sides many people have...

I wanted to as long Z travel as possible, so I used steel channel for the Z plate. The fusion360 sim showed that a flat plate would flex a lot.

Your build is very impressive and it looks really nicely finished.

Do you make any mistakes at all???

Would have done anything differently?

So how did you do the epoxy on the gantry? I can see you have rails on the top and underside of the gantry (good design to keep Z close to the gantry!), so the top epoxy would be easy! The bottom????
