I'm rebuilding a printer for a friend, it's a Tevo Tarantula. If you ever hear the words Tevo & Tarantula mentioned in the same breath do yourself a favour and head for the nearest exit. II could really go off on a tangent here but I'll leave it at that.
I's got an MKS Base V1.4 board with dual Z nema 17's, one is attached the Z driver and the other one is running from E1. They are driving the gantry through lead screws. They sync up and run excellent but they run really hot on a large print where there isn't much movement on the Z axis.
I understand this is a normal phenomenon for a stepper holding a load in a static position but do they really need to be on while they aren't driving the lead screw, will the gantry work back downward from vibration etc if they are off?
Is there a way to set their state when the Z axis isn't being driven?
I'm running Marlin 2.0 bugfix but it's a pre rolled version (Jim Browns Easy config) so I haven't dug into much except to reverse the Z axis direction and enable the stepper on E1.
