Review: Misleading - Misleading It says in the description that this unit comes with a rotary drive. I did not get a rotary drive. Review: Very good engraver, if using Linux and LightBurn there is a startup trick - Let's start with the drawback, if you use Linux, this engraver requires a load of the FW over USB before it is recognized. Without doing this, LightBurn couldn't see the device and let you set it up. I found someone on the LightBurn forum that wrote a python script that worked with the windows lmcv2u.sys (32-bit version) that allowed this to load. After that, LightBurn could find the device, and it seems to set it up after that. Once that was sorted, I followed the instructions to get the settings right and have been playing with various things since. I have done stainless steel, copper, brass, anodized business cards, slate, and as the pictures show, rocks from my yard. The initial start-up was frustrating, but the laser itself has been fun. On a side note, the staff at the customer support has been helpful and looking to improve, hopefully they will provide the files needed to get this set up easier in the future. But their communication has been a plus in my eyes, and what brought this from a 4 star to a 5 star review. Now onto my thoughts on the engraver. The details it produces are out of this world. This is does such a good job engraving, the rocks in the picture are sitting on paper towels, you can see they aren't that big, yet the detail is stunning. Adjusting the height is really easy, for a introduction to fiber lasers, this is a great unit. ## Features - [ B4 Specification ] Magical black, 20W, 220V, Max laser source, 2 in 1 desktop and handheld fiber laser marking machine, support lightburn software and ezcad2 software (we provide), support rotary(every machine with a rotary drive). the standard configuration 2 lens(working area) 110x110mm + 200x200mm. - [ Package Includes ] 1xB4 machine(magical black), 1x 110mmx110mm lens, 1x200x200mm lens, 1xAdapter, 1xFoot Switch, 1xPositioner, 1xUSB Drive, 1xRuler, 1xData Cable, 1xAllen Wrench, 1x1064nm Goggles,1xRotary Drive, 2xPaperboard, 1xAuxiliary holder, 1x Material package. - [ Parameters ] Laser Wavelength: 1064 nm, marking speed: 0-15000mm/s, frequency: 20-60kHz, system: windows 7/8/10/11, mac (lightburn ), supported graphics formats: BMP, GIF, JPG, JPEG , DXF, DST, Al, etc, Minimum line width: 0.01mm, engraving depth 0.3-0.5mm. - [ Engraveable Material ] Commarker fiber laser engraver can engrave Stainless Steel, Aluminum, Gold, Silver, Alloy,Brass,Ring, Bracelets, Necklaces,etc also can mark some of the Painted products and non-transparent plastics.engraving machine for Metal, Jewelry, Pen,Tag,Tumblers. - Our commarker B4 laser engraving machine adopts high-speed precision vibrating mirror, high marking accuracy, equipped with different field of view lenses, large marking area, fast marking speed, electric lifting, emergency switch, very safe.

I'm drilling the holes on my CNC machine, since the laser will mass the pads, but for all other steps of the PCB - this is great! Look at the image, those are extremely small pads with little space between it, and It handle that! I need to find better clad copper boards, because small pads that are not connected will delaminate from the board. I've bought it mostly for the PCB at home thing, now with the tariff who knows how expensive it will get, and making it at home is so much faster. ## Frequently Bought Together - ComMarker B4 20W Fiber Laser Engraver Machine, LightBurn Compatible Laser Engraving with 2 Different Size Lens,2-in-1 Desktop and Handheld Fiber Laser Marking Machine for Jewelry,Sliver,Gold,Tumblers - ComMarker 5 in 1 Multi Functional Rotary - ComMarker 1 Pcs OD6+ Protective Shields,Laser Engraver Accessories L Shape Portable Baffle,3mm Thickness 1064nm Acrylic Eye Protection(290x219x38mm) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/520403239-b4-20w-fiber-laser-engraver-machine-lightburn-compatible-laser-engraving](https://www.desertcart.tn/products/520403239-b4-20w-fiber-laser-engraver-machine-lightburn-compatible-laser-engraving) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-17*
