RECOVERED CONVERSATION EXCERPTS
USER MESSAGES:
1. When i 3d print flexible material it seems things are moving way to fast

ASSISTANT RESPONSES:
1. When printing flexible filament (like TPU, TPE, etc.), speed is *one of the biggest issues*—if it's too fast, it causes slipping, under-extrusion, stringing, or parts not sticking. You’re right to notice this. Here's how to dial it in for best results:. ✅ Main Fix – Slow Everything Down Try these speed settings as a starting point: | Setting | Recommended Value | |. . --|. . . . . . -| | Print speed | 15–25 mm/s (max 30) | | Travel speed | 80–100 mm/s | | First layer speed | 10–15 mm/s | | Retraction speed | 10–20 mm/s | | Retraction distance | 0.6 – 1.2 mm | | Infill speed | 20–25 mm/s | | Wall speed | 15–20 mm/s |. ⚙️ Other Important TPU Settings 🔧 Extruder Type - Direct drive = ideal for flexible filament…

EXTRACTED KNOWLEDGE / HOW-TO
- --
- Direct drive = ideal for flexible filament
- Bowden system = much harder → slow it *even more* and reduce retraction
- Print a single-wall cube at 20 mm/s.
- If it looks good → slowly raise speed (2–3 mm/s each time).
- When quality drops → back off to last good speed → *that’s your maximum*.
- Add a filament guide at the extruder (prevents bending)
- Keep TPU dry – moisture will ruin prints
