ASSISTANT RESPONSES:
1. Nice part for TPU 👍 — that’s basically a flexible grip pad, and a 0.6 mm nozzle is actually ideal for this size and material. From the screenshot it looks like a textured, slightly domed rubber-style pad (about 5" × 2" × ½"), which means strength, layer bonding, and surface finish matter more than tiny detail. Here’s how I’d run this on your Flashforge Adventurer 5M with TPU and a 0.6 nozzle.. 🔧 Orientation (this matters most) Print it exactly like shown Flat bottom on the bed Textured side up Do not stand it on edge — TPU will wobble and ruin surface quality.. 🧵 Nozzle & Layer Height | Setting | Value | |. . -|. . | | Nozzle | 0.6 mm | | Layer height | 0.30 mm | | First layer | 0.35 mm | TPU likes fat laye…
2. Yeah — this screen is exactly why TPU prints are going bad right now. Orca is treating your TPU like PLA 😅 Right now you’re blasting 100% fan, forcing slowdowns, and forcing overhang cooling — that will make TPU weak, stringy, and warped. Let’s fix it.. 🔥 TPU Cooling Setup (Flashforge TPU 95A) On this Cooling tab, change ONLY these:. 🧊 1) Top Section — Layer-based cooling Set this: | Setting | Value | |. . -|. . | | No cooling for the first | 3 layers ✅ | | Full fan speed at layer | 0 (leave it — we won’t use it) | We will control fan manually below.. 🌀 2) Part cooling fan Change this entire block to: | Setting | Value | |. . -|. . | | Min fan speed threshold | 30% | | Max fan speed threshold | 30% | | Kee…
3. Great question — TPU brims behave very differently than PLA, so the removal technique matters a lot if you want clean edges. Here’s the safe way to do it.. 🧰 What you need - Fingernails or tweezers - OR a plastic scraper (Do not use a metal scraper — TPU will tear and stretch). 🪛 Step-by-step (this avoids tearing) 1. Let the bed cool to room temp TPU releases better when cold. 2. Lift one corner of the brim ring Use a fingernail or tweezers to grab the brim — NOT the part. 3. Pull sideways, not up Pull the brim parallel to the bed, like peeling tape off glass. 4. Go slowly around the part The brim will usually come off as one big rubber loop. 5. If a fuzz line remains: Rub it with your thumb — TPU balls up a…

EXTRACTED KNOWLEDGE / HOW-TO
