網頁2024年12月30日 · For the X/Y/Z axes, you can use M92 to change the axis steps per unit to a negative value, which causes it to move in the opposite direction. I.e. if normally your X axis has 160 steps per mm, using M92 X-160 will invert all of its movements. However, this is more of a hack than a real, intended solution. 網頁2024年7月30日 · The 4 step sequence that we send to the stepper motor interface is 88H, 44H, 22H and 11H instead of 08H, 04H, 02H, 01H so that the step motor can be connected to any one of the two connectors provided on the interface board.
