Hi! I have a question about this.
I’m using high-flow extruders that require quite a lot of current — in fact, I’m testing some at 1.5 A, reaching around 200 mm³/s with 2.85 mm filament.
However, there’s one thing I’m wondering about: since the extruders are not always active, would it be suitable to reduce the hold current when they’re idle? I know it’s generally not recommended for regular stepper motors, but in this case, I’d just like to keep the extruder cooler when it’s not being used.
By the way, I’m also cooling the extruder itself with a liquid-cooling system — not just the hotend, haha.
