If you were a Mac user trying to get into laser cutting a couple of years ago your options regarding software would have been quite limited. You could either:

In the final part of this series we finally start cutting things with the K40 laser cutter! We will transfer our designs created in Inkscape to an application called K40 Whisperer from Scorchworks. Now you might be thinking “But the K40 comes with its own software, can I just use that?” Well, yes you can, but I’ve found that K40 Whisperer is a lot easier to use, and it even runs on Linux. K40 Whisperer is written in python so it is possible to run it on Windows, Linux and Mac. However there are a lot of dependencies that need to be satisfied in order to successfully use the program. These dependencies are resolved on windows by packaging them in the pre-compiled executable version of K40 Whisperer. For Linux and Mac additional work will need to be performed by the. K40 Whisperer reads SVG and DXF files, interprets the data and sends commands to the K40 controller to move the laser head and control the laser accordingly. K40 Whisperer does not require a USB key (dongle) to function. K40 Whisperer is a free open source program released under the GNU General Public License (GPL). K40 Whisperer Features.

Total newbie with a K40 with M2 nano control board. Downloaded latest versions of Whisperer and inkscape (windows 7 laptop). Whisperer is initializing the K40 fine (as in; it will move the laser head etc.) but when I try to open an SVG file it says it can't find inkscape (if I leave inkscape executable field empty, that is).

Buy a cheap PC and install windows on it (popular option even today because you probably don’t want to keep your Mac in the workshop)
Run Windows in a virtual machine-based environment on a Mac or
Go for an expensive top brand machine that comes with proprietary “print drivers” for Mac OS.

Luckily, technology and software are developing rapidly so in this day and age there are plenty of options (paid and free) to choose from if you are not Windows OS user.

Now, before we get started it’s important to make a distinction between laser control software (which is software that communicates with laser cutting machine) and laser design software (app used to create graphics). There are few laser controlling software that offers some designing capabilities and in recent years they got better from designing point of view. But even so, for any serious designing you will need to use proper vector drawing app because control software is just not as capable (which is understandable, it’s not meant to be a drawing software).

We will skip option a) since it is pretty straightforward and not relevant for this article and go straight for the next one which is…

Run Windows on a Mac

This option is best used if you have a specific program that you want or need to use which works only on Windows. Controllers in Chinese manufactured laser cutting machines use specific software which is usually windows based (RuiDa controllers work with RDWorks software, Trocen controllers with LaserCAD etc…) so if you want to use this type of software you will need a Windows environment for that. If you have one of these Chinese controllers there is alternative software that works on a Mac, but we will get to it later in this article.

If you don’t want to go for option a) (buy dedicated Windows machine) but still want to use Windows-based software you can install windows on a Mac OS as a virtual machine using Parallels application. With the Parallels app you can run Windows OS inside an app so you can have windows and Mac apps side by side. This will allow you to use best from both worlds and seamlessly copy and paste between 2 operating systems. It’s easy to install and workflow is quite fluid as long as you have enough RAM to accommodate both operating systems. The downside to this is the price. Parallels license cost $80 which is steep for this type of software and you still have to buy a license for Windows. There is a free alternative to the Parallels app called VirtualBox which is not as smooth as the Parallels app but still more than usable.

Another option is to create a dual boot system with Boot Camp, but this is not nearly as practical. If you use Mac to design and windows to run laser control software you would need to reboot your computer and switch an operating system every time you have to make modifications to your designs. This will get tedious quite quickly. At that point it’s better to go and get cheap used PC, install windows on it and share files over the network.

Brand related software

Top brands in laser manufacturing businesses like Epilog or Trotec offer their laser control software in a form of print drivers and they have Mac version of these drivers. You need to have some vector drawing software (like Adobe Illustrator, Affinity Designer, or Corel for Mac) you will use to create a graphic that you can then “print” on a laser cutter using provided print drivers. But these machines are quite expensive since these are machines from top branded, western manufacturers.

There are some more affordable brands (like GlowForge, Full Spectrum Laser, and Dremel) that have also created software for their laser cutters.

GlowForge has a web-based software for which you gain access when you buy a laser cutter from them and which you use from your web browser. The problem with this is that the app itself is hosted on GlowForge servers so internet access is required for you to be able to use it.

Full Spectrum and Dremel also provide their software (Retina engrave and DigiLab) through a browser but the difference is that the app itself is hosted locally on the machine itself so you can use it even without an internet connection. You only need to have your PC and the machine on the same network.

Since all these apps are browser-based they will all work on every OS including Mac of course, and you will not have to install anything for it to work, just connect your laser with your computer and you are good to go. Another good thing with all of this browser-based software is that they all offer some designing tools so you don’t need to have additional vector drawing software. But this is only true for some basic jobs and for anything more complex you will need to use some dedicated graphic software.

The downside is that these machines only work with provided software (however good or bad you find it to be) and you can’t use anything else because of the integrated controller is made to communicate with that software only.

Other software

K40 Whisperer + Inkscape

Chinese K40 lasers are the cheapest CO2 lasers you can find and because of that are quite popular with beginners and hobbyist. They usually come with old M2 nano controllers and Windows-based LaserDRW software + some older (and probably pirated) version of CorelDraw. To make these lasers more user friendly the guy from ScorchWorks created K40Whisperer which is (thankfully) Mac compatible. Installation can be a bit tricky since you’ll need to use the command line but it’s doable and free. It also requires you to have Inkscape installed (you can find a Mac version on the official website inkscape.org).

Inkscape is quite powerful yet free and open-source vector drawing software used by many in the laser cutting community. Great community around this software help
