You just unboxed a Sculpfun laser engraver and want to run it from your Mac. For years that meant working around the software Sculpfun pointed to, LaserGRBL, which is Windows-only (see our LaserGRBL alternatives for Mac guide). That changed in August 2026, when Sculpfun added a macOS download of its own free app, Sculpfun Space. And every Sculpfun machine speaks GRBL, an open protocol over USB serial, so any Mac-compatible GRBL controller can drive it too.
This guide walks you through the entire setup process, from driver installation to your first engraving, using macOS.
Until the summer of 2026 Sculpfun had no Mac software at all: its documentation pointed to LaserGRBL, a free program built exclusively for Windows. Sculpfun has since released Sculpfun Space, a free all-in-one app for design and engraving, and its software page now offers a macOS build next to the Windows one. We compare it with the other Mac options in Step 2.
Either way, Sculpfun machines are not locked to any specific software. Under the hood, they run a GRBL firmware that communicates over a standard USB serial connection. GRBL is the same open-source motion controller used by CNC routers, 3D printers, and laser engravers worldwide. Any software that speaks GRBL can drive your Sculpfun — regardless of operating system.
What you need is a macOS application that can open a serial connection, send GRBL commands, and convert your images and SVG files into G-code. Let us get your Sculpfun running on your Mac.
Sculpfun laser engravers connect to your computer via USB, using one of two common USB-to-serial converter chips:
If you are running macOS Sequoia or newer, you are in luck. Apple now includes built-in drivers for both CH340 and CP2102 chips. Simply plug in the USB cable and macOS will recognize the device automatically. No driver installation needed.
If you are on macOS Sonoma (14) or earlier, you may need to install a driver manually. The CH340 driver is available from the WCH manufacturer website. Download the macOS version, run the installer, and restart your Mac. For CP2102, Silicon Labs provides a macOS driver on their website.
After plugging in your Sculpfun via USB:
If the device appears in the USB tree, the driver is working. If it does not show up, try a different USB cable (some cables are charge-only and lack data lines) or a different USB-C adapter/hub.
Still not showing up? Some controller boards are never detected when plugged straight into a modern Mac's USB-C port and need a powered USB hub instead. See the full troubleshooting checklist in our FAQ: my Mac doesn't detect my laser engraver.
Several Mac-compatible options exist for controlling GRBL laser engravers:
Sculpfun Space is free and made by the company that built your machine, which makes it the natural first thing to try. Its Mac build is new, though, and as of September 2026 it comes with limits the download page does not mention:
| Sculpfun Space | Lùmen | |
|---|---|---|
| Price | Free | €19.99 one-time, 3-day free trial |
| Machines | Sculpfun only (not the G9/V5 galvos) | Any GRBL diode laser: Sculpfun, Ortur, Atomstack, TwoTrees, NEJE… |
| Macs | Apple Silicon only | Apple Silicon and Intel |
| macOS version | 13 Ventura or later | 15.6 Sequoia or later |
| First launch | Blocked by macOS until you allow it in Privacy & Security | Opens normally (signed and notarized by Apple) |

| Built as | One cross-platform app for Windows and Mac | A native Mac app (Swift/SwiftUI) |
Try Sculpfun Space first if you have an Apple Silicon Mac, only ever plan to own Sculpfun machines, and want a camera workflow. Lùmen is the better fit if your Mac has an Intel chip, if you own or might add a machine from another brand, or if you want an app that installs and behaves like any other Mac app. Lùmen also adds WiFi connection, rotary engraving and control from Claude. It has no camera: if camera alignment matters to you, that is a point for Space. And if your Mac is still on macOS 13 or 14 with an Apple Silicon chip, Space runs where Lùmen does not.
This guide uses Lùmen because it is purpose-built for this workflow. It is a native macOS app (Swift/SwiftUI) that includes built-in presets for all current Sculpfun models: S30, S30 Pro, S10, S9, S6, S6 Pro, and C1 Mini. Each preset configures the correct work area dimensions, maximum laser power, and speed limits automatically — no manual GRBL configuration needed.

The laser head will move to its limit switches and establish the coordinate origin. This is essential before your first job.After homing, the status indicator should show Idle with coordinates at or near 0,0. Your Sculpfun is now ready to engrave.
Let us start with a simple image engraving on a piece of scrap wood.
Click Import Image and select a JPG or PNG file. A good first test is a high-contrast photo or logo — something with clear light and dark areas.
Laser engravers cannot produce shades of gray. Instead, they simulate tones by varying dot density, much like newspaper print. Lùmen offers 7 dithering algorithms. For your first engrave on wood, select Atkinson. It produces higher contrast with less fine detail, which tends to look better on natural materials and is more forgiving of imperfect focus.
For a typical Sculpfun diode laser (5W optical power) engraving on untreated wood, start with these values:
These are conservative starting values. You can fine-tune later using Lùmen's built-in test pattern generator, which creates a power-vs-speed calibration grid to help you find the perfect settings for each material.
Drag the image on the canvas to position it within the work area. Use the Frame button to have the laser head trace the outline of your engraving area without firing the laser. This lets you verify the position and size on the actual material before committing.
Tip: enable the Laser Pointer during framing. The laser will fire at a very low power (S10), drawing a visible dot that traces the boundary on the material so you can see exactly where the engrave will land.
Press Start. Lùmen begins a 5-second safety countdown (put on your laser safety goggles now), then homes the machine and starts engraving. You can monitor progress in real time on the canvas and adjust power and speed overrides on the fly if needed.
Beyond raster engraving, Sculpfun machines excel at cutting thin materials like plywood, acrylic, and cardboard. For cutting, you work with vector files (SVG) instead of raster images.
Lùmen supports a dual-layer workflow: you can combine an engrave layer (raster image) and a cut layer (SVG) in the same project. The engrave runs first, then the cut — perfect for projects like engraved coasters or custom keychains with cut outlines.
All current Sculpfun laser engravers are GRBL-based and work with Lùmen. Here is a quick reference:
| Model | Laser Power | Work Area | USB Chip |
|---|---|---|---|
| S30 Pro Max | 20W optical | 410 x 400 mm | CH340 |
| S30 / S30 Pro | 5W / 10W optical | 410 x 400 mm | CH340 |
| S10 | 10W optical | 410 x 400 mm | CH340 |
| S9 | 5.5W optical | 410 x 420 mm | CH340 |
| S6 / S6 Pro | 5.5W / 6W optical | 410 x 420 mm | CH340 |
| C1 Mini | 3W optical | 160 x 160 mm | CP2102 |
If your specific model is not listed above, you can create a custom machine preset in Lùmen with your machine's exact work area and power settings.

This is a hard limit alarm. It means the machine tried to move outside its defined work area, or it has not been homed yet.

Your Sculpfun works perfectly on Mac — you just need the right software. Lùmen is a one-time purchase of €19.99 with no subscription, and includes built-in presets for every Sculpfun model so you can go from unboxing to engraving in minutes.
