We have just received the UM2 and after we have printed the UM robot we started with an iphone case. I have leveled the heading glass bed several times but still have a lot of problems printing the first layer. See image:
I don’t think it has something to do with leveling the bed because it is not only one bad corner and i have redone leveling 3 times without any better results.
Layer heigt: 0.06
Print speed: 50mm/s
Temperature standard setting: 260c
Building plate temp: 80c
Used glue stick
Not only are some layers almost transparent that thin but there are also a lot of bumps. The surface is not flat. While printing the glas bed was pushed down because of the bumps. What am i doing wrong?
Also, is there a guide for using the right settings when using ABS with a heated bed? There are a lot of settings but for a newbie it is very difficult to find out where to start and how and why a setting should be applied.
