@AlexBirkett welcome to the forum.
Have you tried to setup the driver as listed in this post Easel Local for Linux? - #17 by SamyKamkar as stated above.
when you download the Linux driver it is compiled to run on a processor that has the X86 instruction set “this is a type of processor”
when you download the mac driver is is compiled to run on a PPC instruction set “this is also a type of processor”
when you follow the directions on the post you will extract the driver source files and compile your own driver for a ARM instruction set “this is the processor used in the Raspberry Pi” only then will you be able to get it to work. “talk to your system” the process is steam lined by @SamyKamkar and he has made this very easy to do.
the Pi is a small very efficient system to use for controlling these machines and there is no fan to draw dust into the system. I use mine with a wireless keyboard and love that I can stand directly over the work piece and move the gantry to exactly where I want it.
