I'm having problems when printing small parts over big areas.
I'm currently printing quite big casing (~180 mm x 100 mm), which has hexagonal holes on the corners. On the first layer the printer prints, in order:
- Supports inside the holes,
- Borders around the holes
- Border of the whole casing and finally
- Infill (since it is first layer, infill is solid)
When printing borders around holes, printer's head travels between all holes (so that's around 90 % of the whole bed width), what results in filament oozing and the hole borders being underextruded (sometimes to the point, that filament doesn't stick to the bed).
My setup is CReality3D Ender 3 with Ultimaker Cura 3. Most important settings:
- Print speed 40 mm/s
- Nozzle temperature 215 °C
- Bed temperature 60 °C
- Retraction on travel turned on
- Retraction additional prime amount set to 0.05 mm3.
- Outer walls printed after inner ones
What would help (I guess) is slowing down the print after long travels or priming more filament, but proportionally to the travel distance. There are no such settings in Ultimaker Cura though.
How can I deal with such problem?
