1250 x 1250 cnc router (from scratch)

nice work. i can see some time has been put in to these drawings.

Pretty confident the guys will tell you to mount the Z rails the other way round.. so the Y plate holds the bearings and the moving Z has the actual rails if you understand? see my machine

I suspect the pro's will suggest more strength under that bed.

To be honest, I took all the useful pointers from the guys on here regarding strength and rigidity and resonance with a pinch of salt..I use 6mm steel box section and 50x100x6 ali for the gantry.... every one of my mates told me its over-engineered.

Now, I sh*t you not. It is only now my machine is working I understand what they were talking about. Its literally got to be SOLID AS A ROCK otherwise you watch the thing flex when cutting hard wood let alone Ali. Your only down the road... Come and watch mine do it before you spend any money
