It works - but adds limitations

The design with the spoilboard /attaching board works. HOWEVER - it also reduces the Z clearance by 9mm. Couple that with the 7 mm you lose with the aluminum 52mm spindle mount - and you really limit your workspace. Consider if you need the extra board space vs. height. I also installed the extended Y rails which gives you the extra length you want - not sure you really need the double bed size. Installed- i was UNABLE to use the laser on 2" blocks due to height. I ended up removing this - i may consider trying it again - but will use joining plates vs the entire board. I may 3d print some. I think this could have been better implemented with a thin aluminum panel of the same size - with a fraction of the thickness.
