Information on our Vectric Laser Post ProcessorWe have been asked by a lot of people to make a post processor to the Vectric Software so it can be used with the laser. You ask and you shall receive! We started one for the X Carve, but it should not really have anything that specific in it to make it unusable for other machines as well. If you would like to modify it the source file can be edited with a standard text editor pretty easily. We have made now specific versions for different machine controllers. If you have a new post processor for another controller that you would like to share, just let us know!This post processor will work with all of the Vectric Products including Cut2D, V Carve, and Aspire. It works with the desktop and the Pro versions.The basic concept is that you set up a tool in V Carve Pro (or other Vectric software) that has the laser parameters to it (the spot size is the drill bit width). Then, you draw in V Carve Pro (or other vectric software) to get the file that you want. When you make your G Code, the post processor will change all of the “retract” portions in the file where the spindle moves up to a laser OFF command. Viola!We have a couple of versions depending on the controller you use.

GRBL LASER ตอนที่ 4 การติดตั้ง GRBL Laser และการ Setup

GRBL Primary Docs Common GRBL/GCode Setups Most GCode-based lasers are pre-configured to work with LightBurn, but if you have a less common machine like a Shapeoko, EleksMaker, X-Carve, or Acro system, you might need to make some simple changes to get the most from LightBurn. Quick Reference¶ You might need to adjust your spindle max RPM value ($30) to match the LightBurn default (1000) or vice versa. The value in LightBurn is called "S-Value Max" in Device Settings. You might need to enable "Laser Mode" if you have GRBL 1.1f or later ($32=1) If you have an older version of GRBL (prior to 1.1f) upgrading the firmware is highly recommended, as Laser Mode also prevents the machine from pausing with every power change. The pause, which happens on older versions, or when not using Laser Mode, will cause excessive burn spots when engraving images. If your machine uses negative workspace coordinates you'll need to apply a workspace offset (G10 L2 P1 xx yy). Set your machine status reporting to be relative to the workspace origin, not the machine origin ($10=0). Make sure the controller is reporting positions in mm, as expected by LightBurn ($13=0) If your machine does not have homing switches (also called limit switches) you will need to home it manually if you want to use Absolute Coords or User Origin modes GRBL Flavors¶ GRBL firmware was originally designed for CNC machines and 3D printers, with laser support added more recently. It is highly configurable, and this is both a blessing and a curse. The "standard" way a CNC machine is configured is somewhat different from the way laser machines often are. Luckily this is easy to change, and easy to switch from one to the other. More recent versions of GRBL (1.1f and up) support two laser-oriented features. The first is Laser Mode, enabled by setting $32=1 in the firmware settings. Laser mode eliminates the pauses that happen when changing power output, because GRBL knows it's controlling a laser which reacts instantly, instead of waiting for a spindle to change RPM. The second is a feature called variable power mode, or the M4 command. In this mode, GRBL adjusts the laser power as the machine speeds up and slows down, making for very consistent cutting and marking. Older versions of GRBL do not have this feature, and simply run the laser at a constant power output for the duration of a cut. Since the machine needs to slow down to take sharp corners, this means corners get over-burnt, while long straight lines end up lighter. This also has the benefit that when the laser comes to a complete stop, the beam turns off (zero speed equals zero

From my previous ARDUINO projects I got a lot of hardware that laid in the basis of this toy. It has helped me to familiarize with the fundamentals of g-code, various free software and its settings.The toy is shown in Fig. 1.MechanicsAs the title says, the toy incorporates two unipolar steppers 28byj-48 (Fig. 2).Four 125mm pieces of 8mm precise shaft were used as well as four linear bearings LM8UU. All this stuff is joined with cable ties (Fig. 3).Since steppers are very slow, a belt drive was the best choice (Fig. 4).There are no tensioners in the design so the proper operation is provided with accurate adjustment of the belt’s length. Ends of the belt are bonded with super glue. As an opposite pulley two ball bearings (inner diameter 4mm, outer diameter 13mm, width 5mm) are used (Fig. 5).A 3.5’’ floppy disk serves as a table. The approximate size of working area is 80x80mm. The table is mounted onto small pinewood pieces with hot glue (Fig. 6).As you might have noticed, the frame is made of metal constructor (Fig. 7). It is important not to breathe near the toy, then everything will be going well)ElectronicsA list of electronic components (Fig. 8):And a laser module of course (Fig. 9)! I used violet(405nm) laser module of 1W power declared. Do not forget following all safety precautions when working with it!The circuit diagram is show in Fig. 10.Firmware for ARDUINO boardWhile I’m writing this, the toy operates on GRBL 0.9jservo – a fork of standard GRBL for support of servomotor and two 28byj-48steppers (link: modification is intended for 2D-plotters where the servo controls a pen moving it up and down. The servo itself is controlled with PWM on D11, but we can replace a pen with a laser.There is also another fork, based on far newer GRBL 1.1f (with optimized Laser mode implemented ), for three 28byj-48 steppers (link: But I found that PWM does not work here. I think this is due to hack for the third axis support. That is why I had to stay on GRBL 0.9j.To work with the laser I changed some settings in GRBL source files:«spindle_control.c»: unlike the servo we need allPWM range (Fig. 11). In addition I increased PWM frequency up to 980Hz (Fig. 12);«config.h»: check if VARIABLE_SPINDLE parameter is defined (responsible for PWM), and set the maximum spindle RPM as 255 (Fig. 13);The firmware is added in ARDUINO IDE trough «Sketch»> «Include libary» > «Add ZIP library», then select «grbl» folder from the archive.Software for PCGRBL receives commands from a computer through USB connection. That is why we have to use a special software such as:Universal G-code Sender, UGS ( – works with g-code files;LaserGRBL. tags: Laser GRBL, download Laser GRBL, Laser GRBL free download, laser engraving, image vectorization, vectorize photo, laser, engrave, engraving, GCode.

Power), meaning that pausing a job automatically turns off the laser. This is not always true with other versions of GRBL. If you aren't already running GRBL 1.1f (or later) on your controller, we highly recommend it for laser use. If this isn't an option, that's ok, but your results won't be as good, and pausing the laser runs the risk of leaving the beam on and ruining the job. Getting Machine Settings¶ Many GRBL based machines allow the settings of the machine to be easily exported or viewed. For advanced configuration like adding limit switches, updating firmware, or setting up a new controller, you'll need to interact with these values. You can do this in LightBurn by using the Console window or the Machine Settings window to copy, update, or reset your machine settings. The Machine Settings window provides you with a formatted table with the parameters labeled. You can also export these settings to a file for later restoration, like we did in our GRBL flashing guide. In the Console, enter $$ to have the controller return the machine's configuration. This will show the settings in plain text, requiring more familiarity with what each command means but allowing you to view the configuration directly, without any chance of mislabeling based on custom vendor configurations. Shapeoko¶ Shapeoko machines typically use GRBL 1.1f, as do newer X-Carve and some other systems, but as they are designed as CNC machines, they are typically configured for negative workspace coordinates. LightBurn doesn't directly support negative workspace coordinates, but you can use a Shapeoko in LightBurn with a workspace offset. Please see the directions in Negative Coordinate Machines for directions to set a workspace offset, clear the offset to use the machine in CNC mode, and create macros to switch modes quickly. You can set these commands up as macro buttons in the LightBurn console window. Enter the first command into a macro and call it "Use Laser", and enter the second command into a different macro and call it "Use CNC". When you want to use your laser, click the "Use Laser" macro button, and when you're done and want to switch back to CNC, click the "Use CNC" button. After setting this, you will also need to make sure your machine is reporting coordinates relative to this workspace origin, instead of the absolute machine zero. Do this by entering $10=0 in the console. X-Carve¶ X-Carve machines sold prior to January 2018 generally run an older flavor of GRBL (1.0c) which does not support the variable power (M4) command, meaning you'll need to use the GRBL-M3 device in LightBurn. Machines sold after that date use GRBL 1.1f, and will work with the standard

( – capable either to transform a raster image to CNC commands or to manage with g-code files directly.Additionally I recommend:Inkscape ( – vector graphics editor with g-code generation plugins available (though I could not made them working properly);DXF2GCODE ( – converts dxf files to g-code. Many CAD programs support dxf files.Working with LaserGRBLBefore doing anything with our toy it is necessary to define an important parameter in GRBL: number of steps per millimeter along X and Y axes. Connect ARDUINO board through «Grbl» >«Connect», then select «Grbl» > «Grbl configuration» (Fig. 14).As the initial value we can calculate: n = N*R / (π*D),where N = 64 – number of steps per 1 round for 28byj-48stepper;R ≈ 64 – ratio for reducer of 28byj-48 stepper;D – diameter of belt pulley, mm (12mm in my case).After the first test burning the initial value was altered to 103, 476 step/mm. After all changes has been made hit the «Write» button to download new data into microcontroller’s memory. Final step: laser focusing. As it is stated in the official documentation ( PWM is set by the command M3 SXXX, where XXX – number from 0 to 255 (i.e. 0 – minimal and255 – maximal power).To focus the laser we do not need the maximal power so just type, for example, M3 S10 in the special field in LaserGRBL (Fig. 15).We get a weak but visible light spot which then can be adjusted to the minimal size using ring on the module.Send M5 command when it is done. Now our toy is ready to burn.Open raster image in LaserGRBL:«File» > «Open File» (Fig. 16). I used logo of Faculty of Rocket and Space Engineering( of National Aerospace University «Kharkiv Aviation Institute».Process the image with filters available in LaserGRBL (Fig. 17). The description of all settings can be found at the official website of the program.Click «Next» and define Engraving speed, Laser options, Offsets and Sizes of the image (Fig. 18).After hitting «Create!» button we get visualization of laser trajectories. Since there are no end stops, before burn something, check twice the position of the laser module (its current position is marked as «plus»). To adjust the position a pad in the left bottom corner and «Set New Zero» button should be used (Fig. 19).Select «File» > «Send To Machine» and enjoy the process. It may take hours depending on line density, image size. And do not forget about how slow our steppers are. After several tests on plywood I thought it would be nice to have a logo on phone’s rear cover (Fig. 20).The video of engraving process:
