Prusa XL - PETG + PLA
Selected 0.20mm BREAKAWAY FULL
- fillament settings/advanced/minimal purge on wipe tower - 35mm
Pick a single extruder for the wipe tower - PETG extruder:
- Print settings -> Multiple Extruders -> Wipe tower extruder
- Print settings -> Multiple Extruders -> Stabilisation cone apex angle (under wipe tower):85
PETG As PLA support
Print Settings - soluble full
Print Settings -> Support Material: With Sheath around the support : disable
Set the extruder where you put the petg (by default it selects extruder 2)
Print Settings -> Multiple Extruders / support material/raft/skirt extruder
Print Settings -> Multiple Extruders / support material/raft/interface extruder:
Note: This feature can only be used with Organic Supports when using a Wipe tower. Changing the support extruder with any other support style than Organic will disable the wipe tower.
Heat bed temperature:
Print Settings -> Multiple Extruders -> Extruders -> Bed temperature by extruder.
The setting specifies the extruder to take the bed temperature from. Setting it to zero uses the default logic that the first layer temperature is always taken from the first printing extruder, and all other layers' bed temperature is taken from the first extruder that prints the second layer.
I set the bed temperature extruder to 1 with pla and then I modified the pla bed temp to 65 degrees
Support Style
When using snug supports, check in the sliced object for parts of the support material that might be very tall and thin, as these might fall or break in the middle of the print. If you notice them in your sliced object, we recommend changing the support pattern, and/or changing the support style to grid.
When using organic supports, don't use interface layers, or they will create unprintable artifacts.
Bed Temperature
Try bed temp of 65degrees and use satin sheet
