Usually considering the driving ability of the stepping motor, the friction of the mechanical assembly, and the bearing capacity of the mechanical components, the maximum speed of each axis can be modified in the manufacturer parameters, and the maximum speed of the three axes when the machine tool user actually uses is limited. A manual pulse generator (MPG) is a device normally associated with computer numerically controlled machinery or other devices involved in positioning. It usually consists of a rotating knob that generates electrical pulses that are sent to an equipment controller. The controller will then move the piece of equipment a predetermined distance for each pulse.

Set the return mechanical origin parameter in the manufacturer parameter according to the installation position of the three axis zero point sensor. When the settings are correct, you can run Back to Machine Origin in the Actions menu. First single axis return, if the direction of motion is correct, continue to return, otherwise you need to stop, reset the direction of the machine origin in the manufacturer parameters, until all axes can return to the machine origin.
Set the automatic fueling parameters (set smaller, such as 5 seconds plus oil), observe whether the automatic fueling is correct, if it is correct, set the automatic fueling parameters to the actual required parameters.
Check if the set values ​​of the electronic gear and pulse equivalent match. You can mark it on any axis of the machine tool, set the coordinates of the point to the working zero point in the software, and use the direct input command, jog or handwheel to make the axis travel a fixed distance, and measure the actual distance with the vernier caliper. Whether it is attached to the coordinate display distance in the software.
Determine the presence or absence of a pulse. You can use an intuitive method: use a sharp knife to point a point on the workpiece blank, set the point as the working origin, raise the Z axis, and then set the Z axis coordinate to 0; repeatedly make the machine move, such as empty knife run A typical machining program (preferably with three-axis linkage) can be paused or stopped during machining, then returned to the workpiece origin, slowly descending the Z-axis to see if the tool tip matches the point on the blank. If there is any deviation, please check the type of pulse signal received by the stepper driver and check if the wiring between the terminal board and the driver is incorrect. If there is still a boring or lost step, adjust the acceleration and other parameters in steps 10, 11, and 12.
