FREQUENTLY ASKED QUESTIONS (FAQ)

1. Can this machine cut through 6061 Aluminum? Yes, with the 500W spindle it can mill aluminum. Recommended pass depth is 0.1-0.5mm with appropriate feed rates.

2. Is it a complete DIY kit or pre-assembled? The main XY and Z modules are pre-assembled; users only need to connect the modules and wire the controller.

3. What software should I use? It uses GRBL-based software like Candle for milling and LaserGRBL or LightBurn for laser tasks.

4. Does the 40W laser require goggles? The module includes an eye-protection cover, but wearing safety goggles is always recommended during operation.

5. Can I use the laser and spindle at the same time? No, they share the same control port and should be used one at a time for their respective tasks.

6. What is the "Z-Probe" used for? It allows the machine to electronically sense the material surface, making it easy to set the "Z-zero" point.

7. Will it work on a Mac? Yes, the GRBL controller is compatible with Windows XP/7/10/11 and Mac OS via UGS.

8. Can I engrave on stainless steel with the laser? Yes, the 40W module (10W optical) is powerful enough for light engraving on stainless steel and anodized aluminum.

9. What happens if I exceed the engraving range? The machine is equipped with limit switches on both ends of the X, Y, and Z axes to stop movement and prevent damage.

10. How do I transfer files to the offline controller? Save your G-code to the included SD card, insert it into the controller, and select the file from the touchscreen.

11. Is the spindle speed adjustable? Yes, the spindle supports 0-100% PWM speed adjustment via software.

12. Do I need to add oil when engraving metal? Yes, lubricating oil is highly recommended to reduce friction and keep the material cool during metal milling.

13. What is the maximum travel speed? The machine can move at a maximum speed of 5000 mm/min.

14. How long does assembly take? For most users, assembly and initial wiring take between 15 and 30 minutes.

15. Does it support a 4th axis? The standard board is a 3-axis controller; 4-axis support would require a board upgrade.

16. Is it suitable for total beginners? CNC operation involves a learning curve in design software (CAD/CAM). We recommend utilizing community tutorials for the software part.

17. What is the optical power of the 40W laser? It has a 10W optical output power, which is the actual laser energy hitting the surface.

18. Can I cut acrylic with the laser? Yes, it can cut dark-colored acrylic up to 3-5mm thick.

19. What size are the stepper motors? It uses high-torque NEMA 17 stepper motors with a 48mm length.

20. Is there an emergency stop? Yes, a dedicated emergency stop button is integrated into the control box for immediate shutdown.
