I thought I did a decent job with levelling the bed. I decided today to be more picky about calibration of the bed on both units. Today's small tests went well.
As for the glue, if I am using the Ultimaker branded PLA or colorfabb what should my bed temp be to allow for it to stick easy, not warp and easier removal when it is done? What tool do you use/recommend to remove your projects from the bed? I am thinking some sort of thin metal spatula or is there something else to use. Just worried about warping/damage when removing large based projects or small projects that may not have much fill <20%.
