Hi all. I am also new in printing with ABS. My question is more simple. I have a UM2 Extended. Could anybody share his UM profile for printing with ABS? I first started with PLA and after some small tuning I got very good results without any modification in my UM2E, but when I switched to ABS the nightmare started. First problems with bed adhesion, by the way, it was solved just by using a BRIM and HAIR SPRAY. About ABS print quality, I have been seing in many forums that the max quality that I can get in UM is just 0.2mm in layer height, is that right? I have been reading many UM2 improvements to get better results as: - Print a improved version of feeder - Print Bearing Spool and Bearing Guide - Make a enclousure for UM to take dust and temperature under control - Changes in the extrusor I think it could be a good idea if the more expert guys could share his UM profile. It is very easy with cura. We could add the following info: - UM model - Cura version - Filament Material - Nozzle diameter - UM changes from fabric (feeder, extrusor, enclousure, dust filters, etc) It would be nice if you could give references about these changes (URL where this change was extracted or some reference) - Other comments: small changes depending the color of the material. Of course if somebody thinks I am missing anything, please don't hesitate to add more points. : ) In this way, anybody would be able to print wihout having to face the same difficulties. This would be really nice and save a lot of time and money to non expert people. Thanks in advance to any people who want to share his knowledge in this way. Mabe we could create a new section for sharing these profiles. Any remark will be appreciated. Best regards I would be surprised if a different filament makes a huge difference but will be interested to hear your result. I have struggled with ABS adhering as well and my solution has been the following: 1st. Enclose the printer. My environment is drafty and somewhat cool and ABS hates this. Here is the cover that I now have. 2nd. I bought an extra piece of glass for the build platform and keep it covered with Klapton tape. I know this is a pain but it is part of the solution. You can get 150mm wide rolls from China and once you have done it a couple of times application is actually pretty easy. 3rd. Very (very) light layer of abs goop. 4th. Finally, and a lot of people hate this as well, but if the bottom surface of the print it non critical, I will use a raft. I find that without the raft the next step is essential but can lead to damage to the tape. 5th. If you are not using a raft then you have to lay down the first layer of plastic with enough pressure to make a good adhesive! I tune the platform using the piece of paper method and with the nozzle pressing enough on the paper that I can feel a little resistance. I then watch the first layer extrude and make some adjustment then if needed. Use extra startup loops a little ways from the part to give your self time. 6th. I keep the build platform at 110c the entire time and I print both ABS and PLA at the very lowest temperatures that I can...this takes experimentation and can vary from filament to filament. This actually does not help with adhesion but I mention it more as an ABS technique that seems to be different than what I read above. Good luck!
