RE: ABS problem
Im using 0,6mm brass nozzle with a silicon "glove"
RE: ABS problem
For one thing those extruder parts arent really designed to be printed with a 0.6mm nozzle. Other first impressions in that the first layer could also be too low. You often have to redo your live z value for different materials, so even if you have it perfect for PLA prints it may not be for ABS.
A picture is great but when it comes to things like this a picture AND your saved project file is better. File> Save Project As and then get the resulting .3mf file and zip it up and attach it. The forum wont accept most file types which is why it needs to be zipped up first.
With the 3mf file it allows people to check out all the settings you used and to potentially slice it themselves and tweak settings/re-slice etc to see if there is any obvious issues.
RE: ABS problem
First layer is to low.
Every new print you have to check the first line that is printed, and if needed adjust the z-layer,
then after the whole first layer is ready, check the first layer, if is OK, if it is sticking enough, or is it releasing and sticking to the nozzle,
or like your picture it is hitting the first layer because the firts layer is to low.(I think).
RE: ABS problem
The first layer is also not sticking enough to the bed, clean everything very good, and if you use glue stick, use only a thin layer, and search for good glue stick, they are not all the same.
