![]() ![]() The Hobb圜NC PRO needs the opposite: invert the stepper enable pin by typing $4=1. Whatever is easier.īy default, the stepper enable pin is high to disable and low to enable. You can change the direction of any (or all) axis OR you can swap the wiring. Inverts the direction signal for each axis. Setting Value Mask Invert X Invert Y Invert Z By default, a step signal starts at normal-low and goes high upon a step pulse event. By changing the values of R2, 4 or 6 you can reduce power even more - or remove the resistor to completely power-down that motor. When the Hobb圜NC PRO board is properly configured (Pin 1 enable), the motors will be cut to half-power when the g-code is done executing. If the pulses are too long, you might run into trouble when running the system at very high feed and pulse rates, because the step pulses can begin to overlap each other.ĭelay 254ms (quarter second) before disabling the stepper motors. ![]() You want the shortest pulses the stepper drivers can reliably recognize.
