Power and Performance
The module operates at 445±5nm wavelength, which is particularly effective for engraving on non-reflective materials. Test results from that same review show the P50 Pro can successfully engrave wood, bamboo, cardboard, plastic, leather, PCB boards, aluminum oxide, and various metal surfaces. However, the module's performance is not without controversy, as forum users on lightburnsoftware.com noted that while the optical power output is advertised at 5W, the actual performance may vary depending on the specific implementation and quality control of the individual units.
Professional testing by hobbylasercutters.com revealed that the P50 Pro's 5W module delivers consistent performance across various materials. The review noted that the machine can handle materials like anodized aluminum and acrylic with good results, though the cutting capabilities are limited compared to higher-powered alternatives. The focus distance test conducted during the review showed that the machine maintains optimal performance when the laser head is positioned at 3mm above the surface, which is consistent with the standard focus procedure for this class of laser engraver. The machine's ability to handle multiple materials effectively makes it a versatile choice for hobbyists and small-scale commercial users.
Build Quality and Design
The Atomstack P50 Pro demonstrates solid construction quality that aligns with the company's positioning in the mid-range market. According to the makeorbreakshop.com review, the machine features 'nice build quality' and 'portability' that makes it suitable for users seeking extra laser cutting abilities. The design includes a touch screen controller that allows for offline operation, a feature that the reviewer found 'handy in the past when I didn't want to connect my machine to wifi and didn't want to connect a computer.' The machine also incorporates a focus bracket system that sits on top of the material, allowing for precise focusing by dropping the laser module until it touches the bracket and locking it into place.
However, the build quality has received mixed reviews from users. The forum discussion on lightburnsoftware.com revealed significant concerns about the machine's construction, with one user reporting that 'the head adjustment nut stripped' on their first day of use. Another reviewer noted that 'the motherboard can only be written to X number times of before it will kill it' and that 'there's a nozzle on the main body that's pressed on so you cannot change the lens if you'd like.' These issues suggest that while the machine may have adequate performance, its long-term durability and maintainability could be problematic. The machine's design includes limit switches on the x and y-axis, which enable the machine to find its home position before every engrave/cut starts, a feature that the makeorbreakshop.com reviewer found particularly useful for repeat cuts.
Software and Control
The P50 Pro supports a range of software platforms including LaserGRBL, LightBurn, Benbox, GrblController, and LiteFire, with full support for Windows and OSMAC systems. The machine can be controlled through USB or Ethernet connections, and also features a smartphone app for wireless control on both Android and iOS platforms. The makeorbreakshop.com reviewer specifically highlighted the machine's external touch screen controller as an advantage over competitors like Ortur and xTool, allowing users to move the machine around, monitor it while running, and load files from a USB inserted directly into the controller. This offline capability is particularly valuable for field work and projects requiring repetitive cuts without computer connectivity.
Despite the software support, user experiences have been mixed. The lightburnsoftware.com forum discussion revealed that while the software compatibility is extensive, the actual user experience can vary significantly. One reviewer noted that 'the motherboard can only be written to X number times of before it will kill it,' suggesting potential software-related hardware limitations. The machine also includes an emergency stop button and limit switches, which the makeorbreakshop.com reviewer described as 'probably one of the best features which I hope that all lasers would have someday.' These features enable automatic homing of the machine, ensuring it always starts from the same spot, which is particularly useful for repeat cutting jobs.
Real-World Performance
The review noted that the machine can successfully handle wood, bamboo, cardboard, plastic, leather, PCB boards, aluminum oxide, and various metal surfaces. The focus distance test showed that optimal performance is achieved when the laser head is positioned at 3mm above the surface. The machine's ability to handle multiple materials effectively makes it a versatile choice for hobbyists and small-scale commercial users who need flexibility in their materials.
However, the performance metrics are not uniformly positive. The makeorbreakshop.com review emphasized that while the machine offers 'the build quality, ease of use, and portability' that makes it an excellent choice for people looking for extra laser cutting abilities, 'the premium power does come at a premium cost.'

Rating sources
“At 20 Watts, the Atomstack X20 Pro has the build quality, ease of use, and portability, making it an excellent choice for people looking for extra laser cutting abilities.”
“The Atomstack A5 M50 Pro should be a very solid laser engraving machine since it has improved mechanical construction and an added offline touch screen controller compared to the previous model the Atomstack A5 Pro.”
“The Atomstack M50 is very good as an upgrade to the 20W Atomstack module. It is genuinely twice as powerful and the beam is narrower and better focussed.”
“I totally agree that with the CNC I no longer need the cutting of the laser and the Atomstack handles the engraving. I now have both in one room versus in the cold garage due to the size of the CO2 machine. So far I have made several gifts for Christmas and very happy with both machines.”
