Homing Your Xmotion Machine

When you first open the CNC Control your presented with a screen that looks like this. It looks like there is a lot going on but it's pretty straight forward if you break it down into small parts.

Notice the DRO (Means "Digital Read Out", and its the box at the top right with the X, Y, and Z numbers). They are red, which means the machine is currently not homed. Our line of Rigid Series machines utilize limit switches for automatic homing but our starter series machines are to be manually homed, so the process is slightly different between the two. For Rigid Series -

1. Click the Red Hand Towards the top right hand side of the screen. This will remove the control

from the default E-Stopped state.

2. Click the Green Power Button Just below the E-Stop button from the previous step. This will power up the motor amplifiers and on Rigid Plasma machines also power on the ATHC unit.

3. Towards the bottom left hand side of the screen there is a button with a cross-hair in the center of a circle with a grey background. This is your homing menu button. Click this menu button to access the X, Y, Z (and A for Rotary Axis enabled machines) homing buttons. It will look like the following.


4. Click the X, Y, and Z buttons (There is no specific order that matters) *Note* - Currently the Home all button all the way to the left does not function. 5. Now click the Yellow back arrow at the bottom left hand side of the screen. Now your machine should be homed and notice the DRO, the numbers will be green. *Note* If you left click the DRO you can cycle through different styles of DRO's and other styles besides the default style won't yield green numbers when the machine is homed.

For Start Series -

1. Click the Red Hand Towards the top right hand side of the screen. This will remove the control

from the default E-Stoped state.

2. Click the Green Power Button Just below the E-Stop button from the previous step. This button will not yield any physical reaction on the machine itself, it is merely for software logic purposes.

3. Next Step is to rotate the Red E-Stop button on the machine control cabinet clockwise. This will power up the motor amplifiers and you will hear a "tunk" sound as the motors receive holding current.

4. Towards the bottom left hand side of the screen there is a button with a cross-hair in the center of a circle with a grey background. This is your homing menu button. Click this menu button to access the X, Y, Z (and A for Rotary Axis enabled machines) homing buttons. (See image of this menu on step 3 of Rigid Series Homing Procedure above)

5. Jog the X axis all the way to it's left hard stop by using the left arrow key on your keyboard. *Note* When the machine is not homed it has no reference to its boundaries and will slam the hard stops. The idea is to lightly bump the axis against its stop. Slamming it should not damage anything but will make an awful racket! 6. Once the X axis is against it's left stop click the "X" home button. You will see the X portion of the DRO switch to Green.

7 . Jog the Y axis all the way to it's front hard stop (Closest to you) by using the down arrow key on your keyboard.

8. Once the Y axis is against it's front stop click the "Y" home button. You will see the Y portion of the DRO switch to Green.

9. Jog the Z axis all the way up by using the "Page Up" button on your keyboard. 10. Once the Z axis is against it's front stop click the "Z" home button. You will see the Z portion of the DRO switch to Green.


Now your machine is homed. If you have homed it correctly you will be able to jog to each axes extent without hitting the hard stops.
