I have had my Robo for 3 years now an now have lost 2 plates due to delamination. Print a part and go back after it has cooled down to find the part pulled up with bits of glass stuck to it. Using ABS and glue stick. Glue stick is he ONLY method I found to keep ABS from warping. In the picture you can see a HUGE chunk of glass came up on my last print leaving me very little bed to work with until I get it replaced.
