My experience with the FLEKS 3D biuld plate on my R1+ so far it works fantastic! I got mine through a Kickstarter campaign it arrived two days ago, installation was fairly easy. I had to more modify my firmware because I had selected the Makerbot 2 model which was a smaller in the X and Y axis than the Robo R1 so I had so set the X axis size to 200mm and the Y axis to 250mm, I never print objects that large anyway so I dont miss the few milimeters at all. The frame is attached to the glass bed with double sideed tape, and centered over the biuld area. next time I would select the 10 x 10 inch model which would fit the Robo R1 better and wouldn't require the firmware changes. My first print adhered perfectly with no warping and did not require bed heating ( FLEKS 3D recommends a maximum temperature of 60 degrees C of the bed). Removing the part was easilly accomplished by flexing the build plate in both directions a couple of times. I was printing with taulman N-Vent transparent filament, I had previously used hair spray on the bed and had limited success as the same part had warped ruining the print. I would highly recommend the FLEKS 3D build plate for any 3D printer users, It eliminates the most aggravating problem that users have of getting prints to adhere to the bed well enough to print, no messy sprays, no need to clean up sticky residue after printing, no masking tape, no Kapton tape, no glue sticks, just print and it works perfectly.
