Anyone selling a used GG3..?

any files for p320/p365 FCUs?

Iso GG3S mainboard. Working with tech support but its taking awhile and i want a back up just in case.

I've been looking to get a GG 3s or A Coast Runner but I don't want to wait until the next batch is shipped, so let me know if any of you got one for sale.

Does anyone know the support number I can call to see what's the update on an order I've placed about 2 months ago I've tried emailing but haven't heard back yet

Does anyone have the codes for the GG3 for the unicorn jig (ggd-store)? I just opened my packages from march 2024 and now the QR code/website links are dead.

What depth or depth range seems to work best? I tried one one on a raw surface. I forget the depth but it seemed a little muddled. Maybe it was the picture quality. Any advice is appreciated

I got a gg3-s with the latest software and firmware.

Recently got my optics cut jigs and optics cut worked great.

Looking at doing some slide porting and saw they have some free downloads. The first error I get is it needed a newer version of ddcut which doesn't make sense.

But then I get some hard stop's.

My guess is it's just a old file that hasn't been updated to the newest release of ddcut but don't know.

So just curious if anyone has done slide porting and what other files may exist out there? I don't mind buying the code if it's for sale anywhere.

Thx

Is there jigs for making uppers? Were can i find other jigs like this

Can you guys send me pics of milled lowers you have made i wanna see how clean the milling is im debating getting a GG3 or a more expensive cnc for very low production lowers. i saw a few posts here with pics and it looked very rough, maybe thats just first trys setups.

Title:

Issue Summary: I recently encountered an Alarm 9 error on my Ghost Gunner 3, which stopped the machine from homing and caused the Z and Y stepper motors to emit high-pitched noises without moving. After detailed troubleshooting, I determined that steel chips (caused by using compressed air to clean workpieces) damaged the PCB and Arduino boards. Below is a complete breakdown of how I identified and resolved the issue, which I hope will help others in the Ghost Gunner community.

Symptoms of the Issue • Alarm 9 Error: Triggered during the homing process, indicating limit switches weren’t behaving as expected. • Z and Y Motors Not Working: High-pitched noise but no movement. • Axes Movability: The Z and Y axes could be physically moved by hand while powered on, indicating no holding torque. The X-axis functioned normally. • No Voltage Output: The PCB wasn’t outputting voltage to the Z and Y stepper motors.

Tools Used • Voltmeter: To measure voltage at the PCB connectors. • Multimeter: To check resistance (ohms) of stepper motor coils. • Command Testing: Using terminal commands ($X, $H, and ?) to clear alarms and verify machine states.

Troubleshooting Steps 1. Checking Stepper Motor Functionality Using Known Good Outputs: All stepper motors (X1, X2, and Y) share the same plug type. • First, I issued the $HX command to home the X-axis. Since it worked, I knew that part of the PCB was functioning. • I unplugged both X1 and X2 and plugged the Y motor into the X1 connector. • Issuing the $HX command successfully homed the Y axis, confirming that the Y motor and its wiring were functioning correctly. 2. Measuring Voltage Output at the PCB: Using a voltmeter, I checked the 4-pin outputs on the PCB that supply voltage to each stepper motor. • Baseline Voltage: ~4-5 V when idle. • Command Voltage: Fluctuated between 24-30 V during joystick commands. • The Z and Y connectors showed no voltage output under any conditions, while the X-axis connectors showed proper voltage. 3. Testing Stepper Motor Coils: I checked the resistance (ohms) of each stepper motor coil. Normal readings are 1.5-2 ohms per coil. • All motors tested within range, confirming they were not faulty. 4. Verifying Limit Switches: After issuing a $X command to clear the alarm, I manually moved each axis into the optical limit switch areas. Then, I used the ? command to confirm that the machine recognized when each limit switch was triggered (open/closed states). • All limit switches worked as expected, eliminating them as the cause of the Alarm 9 error. 5. Clearing Alarms Before Testing: After triggering an alarm, I issued a $X command to clear it before issuing further joystick or homing commands. Without clearing the alarm, the machine will not respond to commands.

Diagnosis

The issue was traced to the PCB and Arduino boards, which were not outputting voltage to the Z and Y stepper motors. The Alarm 9 error occurred because the machine couldn’t home, as it failed to detect the limit switches being triggered.

Solution 1. Replaced PCB and Arduino Boards: I contacted Ghost Gunner support, and Garret from Defense Distributed overnighted replacement boards. After replacing the damaged components, the machine worked perfectly. 2. Verification After Replacement: • Measured proper voltage on all PCB outputs (~4-5 V idle, 24-30 V during commands). • Tested all motors by jogging with the joystick. • Successfully ran $H and verified the limit switches worked during homing.

Key Takeaways • Compressed Air Warning: Never use compressed air inside the Ghost Gunner. Steel chips can damage sensitive electronic components. • Step-by-Step Diagnosis: • Check voltage at the PCB outputs using a voltmeter. • Test stepper motor coils for proper resistance (1.5-2 ohms). • Swap motor connectors (e.g., Y into X1) to test motors and wiring independently. • Use $X to clear alarms before issuing commands. • Use the ? command to verify limit switch functionality. • Community Support: Garret from Defense Distributed provided excellent support and shipped replacement parts quickly.

Final Thoughts

If you encounter similar issues, follow the steps outlined here to identify the root cause. Diagnosing with a voltmeter and swapping connections is key to ruling out motor, wiring, or PCB faults. Feel free to reply or DM with questions—happy milling!

Does anyone have a phone number to anyone that works at Ghost Gunner? I think I need a control board asap, overnighted if possible, and is hard to get anyone on the phone. Thanks!

Has anyone had a limit switch go bad on their GG3?

This is my second lower now and pin holes on both lowers seem oversized. I've tried multiple different lpks to see if it was a tolerance stacking issue and every pin drops straight through both holes no resistance. It appears to be so out of spec I can see the spacing atound the pin when it's in place. I know the springs will hold them in place but this isn't desirable I want the lower to have at least some grab on the pins. Thinking this might be a issue with how tight I mounted the part I was told not to over tighten the jig to prevent flex. I ended up noticing the whole lower flexing towards the chip cover when the 5/32 made contact with the lower so perhaps not tight enough?

So my gg3s is on the way, can anyone give me a list for tools and equipment i need , i have a 3d printer already, my gaol is to basically make everything possible but bolts and maby springs. Even a general equipment shopping list works. I will be looking into smaller builds, maby a few AR but mostly smaller

Obviously GGD is defunct so I'm not getting one there, DD says they're working on making one but who knows when. So, I'm wondering if anyone has one they aren't using and wants to recoup some of their cost on.

Has anyone had success with adding a dovetail for a rear sight in front of the optic cut? What tooling did you use? Do you have a DD file?

I know nothing about this stuff. Where do i start? What equipment do i need? What material are guys using?

My job quit halfway through with a hard limit error. I restarted twice and the same thing happened, each time it got a little farther. End mill is new. Have successfully done many previously. Using the joystick on the ddcut main screen, I'm able to individually home the x and y axis ($HX and $HY), but when I $HZ, the Z only moves about a quarter inch then trips a limit error. I can manually jog all axis, including z, through their entire travel. When I try to home ($H), or run a cut code, it sends an error 8, failure to home. I have vacuumed it out very well. Have reset everything. I'm at a loss. It's not a mechanical issue as I can manually move all axis the full distances. Help. 😆

Hi there does anyone know how to set up a machine in fusion360 to work with gg3 I'm trying to use the generic 3-axis with X on table & YZ on head because it seems the closest but the movements aren't right

Can I make a an op rod for a piston style rifle like bushmaster acr on a gg3 machine? How do I go about finding someone to write program for that??

Anyone here have one they aren’t using or know where I can pick one up?
