Hi All,
After a crazy few months at work I have finally found a few days to catch up on some CNC. I am undergoing a long overdue maintenance of my machine which includes a fixed (and level) bed.
The bed area of my CNC is 1100mm x 450mm and a cutting area of 760mm x 380mm. I have decided on a new bed 1100mm x 380mm to also utilise Rod's side gap clamping method. I bought some 10mm grub screws today for the height adjustment but they just a bit long for my 18mm MDF sheet (arrggh). So I am thinking I will just level the new bed (i.e. mill it with a large cutter) after I screw it flat onto the metal runners.
Rod: if you are out there :) I remember you telling me once that this wasn't ideal but I can't remember why or if was just not the prefered method.
I am going to start to make jigs that I can just clamp straight onto the bed (one that I know is flat :) ).
anybody have a strong opinion on this one?
