Because of the sense resistor in the
stepper driver circuit (which is 0.05 ohms rather than 0.1 ohms, which the
Melzi V2 reference design uses), this effectively means that the stepper
driver is trying to supply the stepper motors with 2.5A when the tirm go to the limit! This is beyond the
limit of the stepper driver (it will overheat and mis-step) and beyond the
current limit of most NEMA 17 Stepper motors, which can get very hot. So that the best choice is buy the custom made NEMA 17 Stepper motors for 3D printer from us.
