USER MESSAGES:
1. Still getting g stringing issues. How long and at what temp would you dry this before printing in the creator 5 pro?
2. I ordered some it should be here tonight

ASSISTANT RESPONSES:
1. Yep. TPU 95A is very hygroscopic, and wet TPU is one of the biggest causes of persistent stringing. Since you're still seeing it after tuning retraction, I'd dry that EONO3D spool before changing anything else. For that 95A TPU, I'd use: - 55°C / 131°F for 6 hours as the starting point. - If it's been sitting exposed for quite a while, go 8–10 hours. - If it's *really* wet—popping/hissing at the nozzle or producing rough/fuzzy extrusion—I'd give it 10–12 hours. - I wouldn't exceed about 60°C / 140°F unless EONO3D specifically says the spool can handle it. If your dryer only has Fahrenheit settings, 130–135°F is perfect. For the Creator 5 Pro After drying, print directly from the dryer if you can. TPU can start…
2. Ahh, gotcha — this is a brand-new spool arriving tonight, not the one you're currently fighting. In that case, I'd actually test it straight out of the sealed package first. TPU is often dry enough from the factory that you shouldn't need to immediately spend 6 hours drying it. When it arrives: 1. Open it and load it directly into the Creator 5 Pro. 2. Print the same stringing test you're using now with the same settings. 3. If the new spool strings dramatically less, we've basically confirmed moisture is the problem with your current TPU. 4. If it strings about the same, then we know we need to attack temperature/retraction/travel settings instead. That's actually a pretty nice A/B test because you're changin…

EXTRACTED KNOWLEDGE / HOW-TO
- 55°C / 131°F for 6 hours as the starting point.
- If it's been sitting exposed for quite a while, go 8–10 hours.
- If it's *really* wet—popping/hissing at the nozzle or producing rough/fuzzy extrusion—I'd give it 10–12 hours.
- I wouldn't exceed about 60°C / 140°F unless EONO3D specifically says the spool can handle it.
- *For this spool tonight: 55°C/131°F × 6 hours. Then run a small stringing test before changing anything else. If you send me your current Creator 5 Pro TPU settings, I can tell you exactly what I'd change after it's dry. [embedded media omitted]
- Open it and load it directly into the Creator 5 Pro.
- Print the same stringing test you're using now with the same settings.
- If the new spool strings dramatically less, we've basically confirmed moisture is the problem with your current TPU.
