Hi fellow shopbotters
I have been following this forum for over a year now, but haven't posted much since my PRT 48x96 with 4g upgrade has been mostly trouble free. Bought it used a year ago. Couldn't be happier with this bot. We have been turning out stairs, furniture components and many signs with it. All turned out excellent or beyond our expectations.
We installed our first 3D sign last friday and am waiting for the next sunny day to take decent pictures. I will post them so I get some of your constructive critics.
But... a problem with the flatness of the table still persists after all my attempts to fix it. When cutting through all the way to the spoil board, a section of the table (near center) seems to be lower because a "skin" always remains in this area.
Doesn't matter if it is solid pine, furniture grade veneered plywood or as the pictures I post here, Gatorfoam.
The material is held by the vacuum pump and I resurfaced the table before proceeding with this cut of nested letters.
What am I missing or how should I proceed to remedy the problem?
Thanks in advance for your help.
