11.3 HOMING and software limit switches test

11.3.1 First homing

When the axes are scaled correctly and the motion directions are correct – it is time to make first
machine's homing. During normal work, most comfortable is to use the button of all axes homing („Ref All
Home" on the main screen). While the tests it is better to home the axes individual from the Mach's
Diagnostic screen.
On the Diagnostic screen of Mach3 you will see group of buttons for each axis homing.
Before you press one - be prepared for emergency stop by EStop pressing or
the Mach screen.
Every time you press Ref... verify homing of each axis. After correct homing – the light
control next to the button should light green. If the motion while homing is wrong, you
can change the configuration in „Config/Homing/Limits".
If axis homing is correct you can experiment with increasing homing speed in the „Config/Homing/Limits".

11.3.2 SoftLimit switches.

Now you can turn on and check the software limit switches. Click on the „Jog Mode" in the manual feed
rate panel and set „Cont.". „Slow Jog Rate" set on e.g. 40%. It is worth to turn on the machine directions
view by pressing on the Mach's main screen. Then, in the manual mode go e.g. with X-axis-5mm
before hardware switch limit and write down from the screen - the X coordinate. Repeat this action for all
axes.
Open the „Config/Homing/Limits" window and enter correct values into SoftMax and SoftMin. For X and Y
axes it is usually SoftMin=0.
Close „Homing/Limits", press
around. You can try and go with each axis to the coordinates specified in the SoftMax/SoftMin. The
machine should smoothly brake and should not cross any border of the working area.
After successful test, you can turn the coordinates off by pressing
After parameters change – the controller goes automatically into the emergency stop mode, it is correct.
After configuration change, you should press
Home" on the Mach's main screen.
