Homing Failure or Timeout
There are different things that can help you resolve this issue.
1. Restore your Ghost Gunner's control board to factory defaults. This simple step alone may resolve many issues. It can't hurt to restore machine defaults if you have an unexpected interruption.
Restore Machine Defaults.
To clear machine work offsets and restore machines defaults, use DDCut V.
Click the Settings button in the lower right corner of DDCut's main menu to access “Machine Options”
Click “Restore Machine Defaults” followed by “Clear Machine Work Offsets”.
The machine will not move, but this should clear any offsets.
Note | This issue will normally be solved by reinstalling the unit's firmware. If not, your machine’s limit switches may need to be adjusted or replaced.
2. If you have a Ghost Gunner 1/2, turn your Ghost Gunner upside-down to access the z and y limit switches. Take care not to lean the GG on the stepper motors while turning it over.
A.) Manually turn the rear stepper motor to move the spindle assembly forward to expose the z limit switch.
B.) With the usb cable connected to your computer and GG, press the the limit switches to see if the LED on the limit switch board lights up. If it doesn’t light up, it may need to be replaced.
C.) See the following image to locate and adjust y or z limit switches.
D.) Use a 2.5 mm ball end allen tool to adjust the 2 bolts to the limit switch. You may need to remove the Ghost Gunner’s rear panel to access the limit switch nuts with a 5.5 mm wrench.
