After breaking my original 3D Systems CubeX Duo touch screen I discovered a solution to a major issue with this printer. This printer has a sticker ( Photos 2 and 3) as the force against the touch screen sensor. Over time the glue gets less sticky and the force needed to keep pressure on the sensor is no longer there. I designed a plastic face to press force upon the sensor to make it work with out issue.

NOTE: If you have never removed the sticker before take it slowly because the touch sensor may stick to the sticker. Take your time to remove the sticker from the touch screen so you don't break it. If done correctly the sticker should look like (Photo 2) with no gold frame. If there is a gold frame you need to carefully remove it and place the + and - on the gold frame upon the screen. If you want a step by step walk through fill free to comment or email me at rubixzcubex@gmail.com I'd be happy to help.
