Same speeds as plain PLA, 40–60 mm/s. If walls look starved when you speed up, raise temperature before you lower speed — under-extrusion at pace is almost always heat.
Bed surface
Same as PLA. Smooth or textured PEI at 60 °C.
What bites people
"PLA+" is a marketing term, not a standard. Two spools with the same label from different brands can want temperatures 20 °C apart — tower every new brand.
Usually wants more heat and less fan than plain PLA. Running it on a stock PLA profile is the most common cause of weak layer bonding on this material.
Tougher means less brittle, not heat resistant. It still softens around 60 °C.
