They are from the set shown below, you can click the photo to see the price on Amazon.

The software is a little unusual, it has a maximum spindle speed of 10, RPM, but is controlled by using a percentage scale of 10 to Therefore setting the spindle speed as S will tell the controller on the to run at 10,RPM.

The spindle speed, S near the beginning of the program, can be changed to suit the machine you are running. To work on the cnc the depth of cut for each pass was kept shallow and the feedrate used was quite slow. The is a Grbl based machine but they also loaded with no errors on a Mach3 controlled machine and the toolpaths looked as they should in the Mach3 toolpath window. The G code was programmed with the goal of being able to run on a cnc engraving machine. You will be able to find out what works and what does not work with your machine. I would encourage you to play with the speeds and feeds, especially if you try the programs on different materials. The programs will give you a benchline of what your machine is capable of so you know what to copy or not to copy when you are creating your own programs. The aim is for you to get familiar with the process of running your Cnc machine successfully and getting repeatable results. This is a quick reference overview of the processes and workflow needed to create programs and to run a hobby cnc machine. So I took the spider program I used in my universal G code sender review and tweaked it to make it available to anyone as a free G code file download. There are a few free G code files online, but they always lack any information about tooling, datum positions or even the size of material you need. I have created a simple G code example for you to download to test out your Cnc mill and practice your workflow for clamping the stock and setting up your cnc machine. There are quite a few articles on this website that will help you create your own programs but nothing beats getting your machine up and running on a project right away.
