Print Profile Notes - I've printed dozens of test parts so you don't have to

This system requires tight tolerances for proper fit and performance. This print is about 2.5 hours if using my provided profile - don't rush a good fit!

• .3mf print file is for Bambu Studio - no modified Gcode

• Perpendicular layer lines - designed to be printed to avoid interlocking layer lines on sliding parts

• Parts are printed by object for consistent layer times and to avoid knocking tall parts off the bed on Z hop travels

• Reduced speeds for improved cooling, layer adhesion, and dimensional accuracy

• Reduced line width for better detail and corners

• 0.14mm layer height for overhang quality

Important:

• Heat-dry your PETG-HF filament before printing.

• Bambu Lab PETG-HF tends to under-extrude with stock profiles. Set your flow ratio between 0.95–0.985 for best results.

• Calibrate Pressure Advance correctly for lower speeds used in this profile for best results

• X1C PA auto cali may not function correctly due to the slower speeds and low volumetric flow used in the PETG filament profile.

• Fit between the front slide cover and backing plate should be a bit tight at first and will loosen up after use inside your heated machine.

Special Attention to Retraction Length

There’s one setting responsible for a surprising number of print quality issues: Retraction Length.

Stock filament and print profiles often use ~0.8mm retraction length during layer changes and a whopping 2mm retraction during AMS cycles. While these are safe values to reduce blobs during travel for a wide range of filaments, it can also introduce air into the melt zone and it's affecting your print quality.

That air can show up as:

• Small gaps in extrusion lines

• Surface defects that resemble wet filament

• Increased stringing

• Under extrusion

If you’re seeing these issues and your filament is dry, retraction may be the cause. Try using Setting Overrides to reduce retraction Length and observe how your extrusion behaviour changes.
