Pull out honeycomb z table?

Postby jofinneg » Sun Oct 21, 2012 3:37 pm

I'm putting together components for a 48" x 36" laser cutter. I'll be using a pre-fabricated xy gantry and attaching it to a Misumi framework.
Since I'll be working with such large sheets, it occurred to me that it would be incredibly helpful to have my honeycomb table able to slide out the front for loading and unloading of sheets. I will be primarily working in 1/4" ply. I do not believe I'll need an adjustable z axis in the foreseeable future, though it would be pretty amazing to somehow integrate an adjustable z with a pull out table.
Has anyone seen this done before?
Any suggestions moving forward with the idea?

Thanks,
John

How about simply putting the front skin on hinges so you can slide your work pieces in? There's no real reason to remove the table, is there? If you cut out a bunch of small pieces, you can just lift them out through the top. If the finished piece is big, slide it back out through the front. If you don't remove the table, Z adjustment is easy.

Set up your optics to include the Z adjustment on the flying head (telescoping final lens mount). Then you don't need an adjustable table. Hinge up part of the front skin with the door so there's a clear opening in front of the cutting grid frame. Put the frame on full extension drawer glides or some linkages which will allow it to lift out of the machine and sit out front for loading and cleaning.
