A: Warm (50°C) is fine. Hot enough to sizzle water (>70°C) will weaken the permanent magnets over time, leading to layer shifts.
A: Yes. Higher speeds require more current to the motors and faster extrusion, which retains heat in the hotend. Reduce speed by 20% if overheating is chronic. extprint3r hot
