Wobblycogs CNC Mk2

[Wobblycogs]

Thanks, as always Jazz your reasoning makes perfect sense on the ballscrews so I'll change then to 1610's. Hopefully this new design will be stiff enough. As for the bely I was thinking I could save a bit of money if I just used a bit of string pulled tight ;-)

Everywhere you see a hole that looks like it should have a bolt there will be one.

This shot is of the base with the new base plate removed showing the new end pieces on the bed rails - these will be bolted on. The corner brackets are still there but they are more to affix the x-axis to the bed rather than hold the whole thing rigid.


The back plate has grown "ears" and bolt holes. Long bolts will run down into the x-axis and the rails at the end of the bed.


There's a new front plate (10mm) which again has bolt holes for the x-axis and the bed.


Finally the base has been covered in a 5mm sheet of aluminium and bolted all over the place for bracing.


I forgot to mention in my first post but the blue bed piece will also be bolted to the bed for bracing.

The only downside I can see of this is chips will accumulate on the front plate, a small price to pay if it's cutting aluminium accurately!
