Download Laser GRBL - Create and prepare the image that you want to employ with your DIY Laser Engraver using this simple and straightforward software solution.
This page has an assortment of that are meant for hobby CNC machine use. Some of these files appear elsewhere on this site and have also been placed here to help keep everything organized.I will try and update this page periodically as I gather together more files, so check back from time to time for more.Also, check out for more. DisclaimerI cannot completely guarantee that the files on this page will function correctly. It is always possible that I accidentally uploaded a previous version of a file that didn’t have all the kinks worked out yet.
Use them at your own discretion and remember that I will not take responsibility for any damage to one’s self, to others, or to one’s property. To put it simply, you can’t sue me if something goes wrong.: ) G-code FilesBecause of the wide range of different CNC machines, it is hard to create G-code that will fit all of them. This is probably the reason why it is so hard to find it on the web. To fill the gap, here are some simple G-code files so that the CNC newbie might have something to try out his or her machine with.These files were all tested to make sure they worked correctly, but I can’t guarantee that I didn’t leave something out accidentally.
I don’t know the limits of your machine, so be careful and practice cutting air first.Use a router bit with a fairly small diameter for these files. (1/8″ or smaller for example.) These G-code files are set up so that the router bit will just barely graze the surface of what’s being cut. If your machine isn’t quite level, the depth of the cut may need to be adjusted to compensate. This cannot be done with the G-code files (at least not easily), but it can be done with the CamBam files below.Click the image to download the G-code file.CamBam FilesCamBam files have the advantage that you can edit them before generating the G-code so that it will work better with your particular machine. Make sure you double check the settings I used because what might work perfectly fine on my CNC machine could cause problems on yours.In case you didn’t know, CamBam is free if you only want to do 2.5D. It can be found.Note: When you open some of these files in CamBam you may have to click and drag over the screen to make the image visible.
I’m not sure why this is and would fix it if I knew how.Click the image to download the CamBam file.FacesUse a router bit with a fairly small diameter for these faces. (1/8″ for example.)GearsHere is an assortment of gears. The tutorial for making them can be found on the page.
They should be all set for turning into G-code, but double check the settings of the 2.5D profiles to make sure they won’t cause problems for your machine.I personally haven’t had the chance to cut some of these gears out, so be careful and practice cutting air first.I already put a hole in the center of each of the gears, but if you want to delete it and put one of a different size, you can do it with CAMBAM.The gears below are meant to be cut with a 1/8″ router bit from MDF 3/4″ thick. The gear on the left has a pitch radius of 1.5″ the gear in the middle has a pitch radius of 3″, and the gear on the right has a pitch radius of 6″. Please note that the pitch radius is actually smaller than the total radius of the gear, so the gears might end up bigger than you expected them to be. These three gears should all mesh with one another if need be.Tutorial GearThis is the gear made in the tutorial.Miscellaneous gearThis is a spare gear file that I had laying around on my computer. It is set up to be cut out with a 1/4″ diameter router bit, but that can be changed in CamBam of course. The gear is about 8″ in diameter.Worm GearHere is a worm gear that can be cut out with a CNC.

Contents.OverviewThe Raspberry Pi CNC board is a simple board that plugs into a Raspberry Pi and turns a Raspberry Pi into a useful little CNC machine controller. (Credit to the GRBL, Arduino, Raspberry Pi and all the wonderful projects on the internet)A basic understanding of the following is needed. (There are many tutorials online covering these topics):.
Raspberry Pi systems. Arduino Hardware / Serial Interfaces.
Basic computer skills. GRBL g-code interpreterWhat you will need to get started. Raspberry Pi B+ / Raspberry Pi 2 or 3 (Raspberry Pi with 20x2 pin header) + accessories like screen, keyboard, mouse. 8GB or Bigger Micro SD Card or bigger. (Internet connection to download the pre-made Raspberry Pi Image).
CNC Hardware - This will not be covered in this wiki but includes things like Stepper Motors+ Pololu Drivers, Linear rails and all the mechanical bits.Download the pre-configured Raspberry Pi imageRaspberry Pi's run a full blown Operating system from it's on board SD card. Pre-configured SD card images are available to speed up the setup process. For this project we created a new image that includes a bunch of applications that can interact with the Raspberry Pi CNC board.Included software:. Standard Raspberry Pi Jesse Image. bCNC: A python based user interface application for controlling GRBL Boards.
CNC.js: A nodeJS web based interface for controlling GRBL boards. Added extras's: MiniCom,XRDP and NodeJSTo install the image follow the standard process as documented by the Raspberry Pi website:Download Install the Raspberry Pi CNC board while waiting for the download. Start by attaching the copper spacers to the Raspberry Pi. Depending on the board there will be 3 or 4 spacers. This was a very quick introduction into using CNC.js. For information on doing more advanced work refer to the website.Links and extra reading.
