I was having bed adhesion issues with very narrow prints, and corners on very large prints with my Robo R1, After trying several types of hair sprays, and glue sticks, I did a search for bed adhesives, and saw Magigoo. They make several types for ABS, PLA, PETG, TPU, etc. I took a chance, and bought the red bottle for ABS & PLA. I was surprised that a little bit applied to the glass bed enabled these prints to adhere immediately, and I was able to print without adhesion or warping issues. When the print was done, I usually have issues removing it, but the print came off easily. It didn't make a mess on the bed either. It seems like one application on the bed works for about 3 to 5 prints before it wear off, and needs another application. It's not cheap at $20 a bottle but I know that it works, and since it doesn't need to be applied for each print, it should last a while. Did anybody else on the forum use it or a similar product?
