3018 cnc vs diode laser engraver: how they cut
The VEVOR 3018PRO cuts by milling: a 60W spindle spins a bit through wood and acrylic, with a stated work area of 300 x 180 x 40 mm. The diode lasers cut and mark with light: the ACMER S2 20W states a 20W diode at 455±5nm, and the LaserPecker LP2 Plus states a 10W diode at 450nm. Milling suits solid parts with depth and shape; laser work suits flat marking and cutting sheet material. The choice turns on what you plan to make.
Power and speed
Spindle watts and laser watts are different measures, so do not compare the VEVOR 60W spindle figure directly with diode output figures. Between the diode lasers, the ACMER states 20W of diode output and the LP2 Plus states 10W. Speed figures also arrive in different units: the LP2 Plus is rated at 4000mm/s, while the ACMER states speeds up to 10,000mm/min. The VEVOR listing states no cutting speed; it states repeat positioning accuracy of ≤0.07 mm instead.
Work area and materials
The ACMER states a 300 x 285mm working area. The VEVOR states 300 x 180 x 40 mm, expandable up to 400 mm on the Y-axis. The LP2 Plus states no fixed bed size; its SpinTrack trolley mode runs along a 2-meter track for signage, panels and batch work, and its cylinder mode handles bottles, cups and tubes. For materials, the ACMER lists wood, acrylic, leather, paper, bamboo, PCB board and ceramic; the LP2 Plus lists wood, leather, acrylic, coated metal and more; the VEVOR title lists wood and acrylic carving and cutting. Never laser PVC or vinyl.
Software and workflow
The VEVOR runs GRBL f1.1 firmware, includes Candle software and supports Easel. The ACMER includes free ACMER Studio software for NC, DXF, BMP, JPG and PNG formats. The LP2 Plus listing states no software package; its workflow centers on the SpinTrack bundle and dual red-dot focus for alignment. A rotary knob on the VEVOR gives spindle control during milling.
Safety and setup
Neither diode listing states a laser class, so plan eye protection and ventilation separately. The ACMER states built-in limit switches that keep the laser head from hitting the frame. The VEVOR states spindle current detection protection that reduces faults. The LP2 Plus states dual red-dot focus for alignment, a positioning aid rather than a safety certification. Cutting and engraving make fumes and chips: ventilate and stay with any machine while it runs.
Choose the ACMER S2 20W if
- You want the higher diode output, at 20W.
- You want a 300 x 285mm work area with air assist.
- You want a 1 Year warranty and limit switches.
Choose the VEVOR 3018PRO if
- You want to mill and carve solid wood and acrylic parts.
- You want GRBL control with Candle and Easel.
- You want an aluminum alloy body and heavy-duty base.
Choose the LaserPecker LP2 Plus if
- You want a portable laser at 3.39kg.
- You want trolley mode for signs and batch work, and cylinder mode for cups.
- You want dual red-dot focus for fast alignment.
Laser cutting makes smoke and bright light. Ventilate, stay with the machine while it runs, keep a fire extinguisher nearby, and never laser PVC or vinyl.
Project Match
- Signs and panels: the ACMER S2 20W with its 300 x 285mm area, or the LP2 Plus in trolley mode.
- Milled wood and acrylic parts: the VEVOR 3018PRO, the only router here.
- Cups, bottles and tubes: the LP2 Plus in cylinder mode.
- Photo engraving and fine detail: the ACMER S2 20W, with a 0.09 x 0.1mm spot.
FAQ: lasers and CNC
Should I buy a 3018 CNC or a diode laser engraver?
Buy the router for milling and carving solid wood and acrylic. Buy a diode laser for marking, engraving and cutting flat materials with fine detail. Match the machine type to the project first.
Can the VEVOR 3018PRO engrave with a laser?
No. The VEVOR listing describes a CNC router with a 60W spindle for milling, carving and cutting wood and acrylic. It states no laser.
Do these machines state a laser class?
Neither diode listing states a laser class. The VEVOR is a CNC router, so laser class does not apply to it.
Can these machines cut metal?
Only in limited ways. The LP2 Plus listing includes coated metal. The ACMER listing does not list metal cutting, and the VEVOR title lists wood and acrylic.
