As @Gero already wrote, you don't need Kapton to print ABS, there are other solutions like Dimafix or the UM adhesion sheets. You cannot do the leveling with a cold nozzle, it would not be accurate enough, because the material expands a little bit after heating up.
surely the heat expansion could be programmed in as an offset?
Could be one way to solve the heat expansion, when it is always the same value.
But UM decided to ship the printer with a glass bed and the active leveling as is, which is most user friendly and follows more the plug and play idea of the printer.
I mean waiting an extra 30 seconds to cool down wouldn't have hurt? By the time it's at the far end of the bed the nozzle is cool and its not leaving any melt marks...Edited by Super_paulie
Yeah I've tried them all and kapton worked the best by an absolute mile for us when using ABS. No brim to remove, no clean up of the part, done. But now we've upgraded to the S5, well that's kinda snookered by this bed leveling with a blazing hot nozzle 🤷🏼♂️
