My first Layer goes down great, but the second layers are terrible. What am I missing, or do not know.
Thank you
Re-check your Z-Offset.
One possibility is your flow rate is wrong but you “fixed” the first layer by setting an incorrect z offset that accommodates the actual flow.
Is layer 2 over or under extruded?
List of settings that effect filament “flow”
Slicer:
- Filament diameter
- Layer height
- Line width
- Flow ratio
These are used to calculate the length of filament needed for each line of G code.
Klipper (printer.cfg):
- Rotation distance
- Microsteps
- Filament dia*
- Flow rate %
- #full_steps_per_rotation: (optional)
- #gear_ratio: (optional)
These convert the length specified in the G code onto extruder motor micro steps.
- As far as I know this is only used to calculate flow rate not the amount extruded. Double check anyhow.
On my Sv07 Christian Vicks Klipper additions really helped the first several layers of the print. I had similar issues with the first few layers for a while.
1.check flow rate in the filament section in your slicer (I use orca) The stock settings were way to high and were causing over extrusion
- make sure your gantry bolts are all tight. Some of mine were loose which caused the gantry to not be perfectly perpendicular to the bed
- consider turning down your first layer flow rate as compared to the rest
