Homing#and#machine#zero#point#
When operating a CNC machine, a homing run is often necessary. Homing defines the so-called reference
points. These are specified by the manufacturer of the machine and are fixed measurements from the body of
the machine. There is always one reference point for every possible axis (traverse path). After homing is
started, all of the reference points of the machine are sought out. This determines the machine zero point
which is transmitted to the controls. By comparing the program zero point with the machine zero point, the
controls can determine the exact location of the tool.
Open the “Settings” window in CNC Studio.
In the “Additional Settings” section, find the parameters “Homing Sequence” and “Machine zero point.” Set the
“Machine zero point” parameter to “front left” and the “Homing Sequence” parameter to “ZXY” or “ZYX.” Those
are the standard settings for machines which have all of the reference switches connected as N/O contact at
the input of the controller card. The “All at once” parameter can be set only on machines that have all reference
switches connected individually to different inputs of the controller card. Save the settings and change pack to
“Program.”
Start the homing run of your machine by clicking on “Homing XYZ.” All axes in succession should seek the
reference switch. After all of the switches have been found, your machine should move to the front left corner.
Upon completion of homing, the coordinate readings will be set to “0000.000.”
Now you have found the zero point of your machine. If no other zero point is set manually, your machine will
start the job process from this position.
Park#position#
Park position is a position of the machine that you can choose at will. This position can be used to change a tool
manually, e.g. Move your machine using the manual controls to the desired park position and then click on
“Save park position.” You can move to this position at any time by pressing “Go to park position.”
