Basic Trouble Shooting
Ghost Gunner 3 | DDcut V/ Settings/ Software/ "UPDATE FIRMWARE"
Ghost Gunner 1 & 2 | Reinstall Firmware
2. Software and DD status: Not connected.
a. If no ghost is detected install drivers manually.
DDCut’s program files are installed by default to C:\Program Files (x86)\DDCut V\Drivers\Arduino.
Click ‘install.bat’ in the Arduino folder to manually install drivers necessary for your computer to detect your Ghost Gunner.
If you can't find DDCut V, in the Program Files (x86) folder, you installed the program only for your user account to use.
Your files are installed at C:\Users\”username”\AppData\Local\Programs\DDCut V\Drivers\Arduino
NOTE: The “AppData” folder is normally hidden. Activate the Hidden items check box in the view menu.
3. 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.
4. Check for damage
a. Verify axes are mounted properly. The spindle assembly should not move freely or shake if you attempt to push it to the left or right. Properly seated ball screw threading should continue all the way to the bearing with no unthreaded portion exposed. The bearing ring should be flush with the mount. Manually turning the stepper motor coupling should cause corresponding motion along the axis without binding.
b. The Y ball screw bearing fits flush to the mount as depicted in this image.
c. The following image depicts the Z axis bearing flush to its mount and Z stepper motor coupling properly attached. The machine’s rear panel has been removed.
5. Proper Collet Installation
a. Make sure the collet is properly seated into the collet nut. The collet should snap into the collet nut when turned at a 45-degree angle. This is so that the collet and nut do not come apart. Slide the tool into the collet-nut assembly. Thread the tool-collet-nut assembly onto the spindle. Push the tool all the way into the spindle then tighten the collet nut to ensure that the tool does not come out while milling. The collet should not be able to fall out of the collet nut once snapped together.
6. Verify Probing
The USB cable connection to your computer powers the Ghost Gunner’s probe circuit with a 5 Volt DC electrical signal. If the workpiece is not properly connected to the probe wire or shorted to the t-slot platform, the end mill may bore into the workpiece during the probing sequence.
a. Verify that the red probe wire is getting voltage. With the GG’s USB cable connected, hold the probe wire away from the machine. Then, proceed to use a voltmeter to measure the voltage between the eyelet of the red wire and the t-slot table. You should read around 5 Volts DC between the probe wire and spindle as well. The probe signal is detectable between 4.5-5.5 Volts DC.
b. If you are unable to detect 5 Volts DC between the probe wire and the spindle using a voltmeter, there may be an issue with your computer’s USB port. Try using a different USB port. If this doesn’t work, try a different USB cable. It is possible that the problem may be with your computer. Make sure the computer is plugged into a grounded outlet and that the computer’s power settings are set to always on.
c. If the probe circuit is functional, the problem may be with your jig setup or tooling. Something is interfering with the probe circuit.
