Hey Everyone, I've had my Robo 3D + for about 2 months now and have been having a great time. I've printed some upgrades that were recommended and installed an E3Dv6. I've read a lot of great advise here that has helped me to avoid a lot of problems and been able to enjoy printing much more. So THANKS for that. Now I want to give back. I recently saw a YouTube video about using PEI on the print bed, so I decided to give it a try. I don't have the link but you can find it with a simple search. I had been using the glue stick then the hair spray. I liked the hair spray the best, but now I've been using the PEI for about a week and it's fantastic. I don't have to put anything down and everything comes off so very easy. I have not had to use a scraper or razor blade to get anything off the bed once it cools down. I got the stuff from amazon, listed below. I put down the 3M double sided tape and stuck the PEI to it. Some trimming and fitting is needed but simple to do after watching the video. I've tried it with PLA, ABS, Flex, and PETG without putting anything on the bed before printing and no problems with adhesion. Here is the stuff I got from Amazon: PEI (Polyetherimide) Sheet, Opaque Natural, Standard Tolerance, ASTM D5205 PEI0113, 0.03" Thickness, 12" Width, 12" Length $16.43 TapeCase 468MP 12in X 12in - 6 per pack Adhesive Transfer Tape (1 Pack) $16.14 YouTube Link: Hope you have as good of luck as I have and thanks again for all the advice and tips.
