Part 7 (print server) The Laser Engraver in a Roadcase has a print server created a Raspberry Pi. The Print Server has 3 functions: It runs CNCjs to view and spool g-code to the laser engraver's Arduino controller. It runs BrowsePy for browser-based file management of the g-code files. And it has a gamepad controller which sends basic setup and movement commands to the laser engraver. CNCjs is available as a Raspbian image or may be installed from step-by-step instructions.
The BrowsePy file manager is a temporary solution until CNCjs adds basic file management. The print server has wired Ethernet as well as wireless networking. The WiFi automatically switches between connecting to known wireless networks and establishing itself as a access point.
The Raspberry Pi SD card operates in read-only mode to minimize the risk of corruption from abrupt power shutdowns. Scripts are installed to easily toggle between read-only and read-write modes. One important note: EleksMaker engravers power the laser at 100% when the Arduino first starts. Pressing the red button - on the printer server - AFTER the Arduino initializes, avoids this safety issue. Links and additional details may be found at gitlab.com/bradanlane/laserbox. Part 6 (etch & inspect) Once the Laser Engraver in a Roadcase has completing the engraving process we scrub the PCB clean of the loose paint residue. The unaffected paint is resilient so its scrub somewhat aggressively.
The best results are achieved using a bristled brush with soap and water. Throughly inspect the traces and the engraving lines. Rinse the PCB in clean water once you are finished scrubbing. The etching solutions is a 2:1 ratio of hydrogen peroxide and muriatic acid. The agitator is made with a continuous rotation server and a simple servo tester powered by a 5V USB adapter. Adjust the agitator speed to maximize the wave action.
The etching takes between 5 and 10 minutes. Remove the paint with lacquerer thinner or other solvent. A final inspection of the PCB under a microscope shows the traces and surface mount pads. It's visible in the microscope the traces are not completely uniform. The errors are a result of the limited accuracy of the laser engraver hardware and controller. This machine can easily produce 10 mil traces.
Smaller traces are possible but not always successful. Basic prototype PCBs are achievable with The Laser Engraver in a Roadcase. Part 5 (engraving) ⠀⠀ The Laser Engraver in a Roadcase uses CNCjs as the printer server software. ⠀⠀ It has a browser interface for computers and large tablets. ⠀⠀ It also has options for a simplified tablet interface and a smartphone interface.
⠀⠀ Using the full interface on the tablet, we load the g-code from the watch folder shared with the BrowsePy file manager. ⠀⠀ For good measure, we use the laser's low power spot mode to verify the start position. ⠀⠀ Don't forget to switch the laser back to normal mode! ⠀⠀ The only thing left to do is start engraving! ⠀⠀ You can see that CNCjs shows the laser position as the g-code is processed by the laser engraver. Part 4 (software toolchain) with The Laser Engraver in a Roadcase The toolchain for making PCBs with the Laser Engraver in a Roadcase starts with the CAD software.
KiCAD is used in this example. Once the circuit design is complete and the PCB layout has been done, create the Gerber files. KiCAD calls this 'Plot'.
We only needs the copper layers. However, it's helpful to also generate the edge cuts layer.
On-line PCB fabricators may require additional layers. The Gerber files are converted to CNC g-code using FlatCAM. After importing the Gerber files we set the origin to the lower left, matching the setup of the laser engraver. We configure the CNC paths to follow the outside of our copper traces.
The best settings will vary depending on the accuracy of the laser engraver. Notice that FlatCAM has a post processor option for laser engravers. The last step is to generate the g-code and save the file. Next, we upload our files onto the printer server using BrowsePy as a lightweight file manager. CNCjs renders the g-code to show the path the laser will travel. Part 3 (PCB alignment) on The Laser Engraver in a Roadcase has a steel plate base which allows us to use neodymium magnets to hold our material. The laser has a spot mode - a low intensity visual mode that allows us to safely see where the laser is relative to our material.
The Raspberry Pi has a gamepad controller attached. This controller allows us to home the laser, set the workspace zero position, and jog the laser relative to our material. We position the laser in the corner of our material and then jog along one axis to make sure our material is square to our workspace. Once we are comfortable with the position of our material, we adjust the remaining neodymium magnets.
Then we can jog back to the 0,0 location. The entire process takes less than a minute and we are ready to go! Part 2 (overview) of The Laser Engraver in a Roadcase started as an EleksMaker clone with a 1000mw 405nm laser module. The carriage is upgraded with a 3D printed tensioner for smoother travel. All wiring is organized with Drag Chains along the X and Y axis or within concealed channels within the frame. The X axis wiring combines into the Y axis drag chain.
Limits switches add homing capability to set the hardware 0,0 position. The modified Arduino Controller provides a PWM signal from variable laser output. The controller has TMC2130 Stepper Drivers for smooth, nearly silent motion.
The gamepad gives direct access to home the machine and Zero the workspace offset. The gampad provides jog control of the laser position with the two shoulder buttons changing the movement scale from 0.1mm to 100mm. The work area has a steel plate with neodymium magnets to hold PCBs or other materials for engraving. The PCB Laser Engraver in a Roadcase!

I finished the 1st test part after upgrading to GRBL v1.1 I wish I could say it was a smooth upgrade but there were a few hiccups along the way. Full disclosure, I am not a software guy. Software I am running now. Arduino - GRBL v1.1 Netbook PC - Universal Gcode Sender Classic 2.0 Netbook PC - Java Version 8 Tip - Update Java to at least version 8 (the latest version) as UGS v2.0 requires it.
Tip - Upgrade Universal Gcode Sender before updating the GRBL software on your Arduino. This way if you have problems with the Universal Gcode Sender (UGS) update you can fall back on the previous rev and keep making parts. Tip - Save the GRBL update for last. You will need to delete the old GRBL rev from your Arduino IDE Library. The files are not located in the Arduino directory on your computer. Mine were located in the 'My Documents' directory. Once the old version is deleted, you can launch the Arduino IDE and install the new GRBL library.
Today I pulled out this other CNC board I had ordered waaay back and thought “let me plug it in and see if the GRBL CNC controller software is already on it”. So I have 3 stepper driver boards that I figured out which way to fit in (without documentation I might add) and I got the correct connection pairs for hooking up the motors after some trial and error with a stepper driver from my already working CNC. So now with some assistance setting the voltages for the motors, I’ll have another CNC brain driving 3 motors (and this one has convenient connector blocks so the limit switches will be easy to install). If it had the ability to drive a 4th motor I’d use it on my first build as that needs 4 motors(2 for the Y axis lead screws). Ordered some parts to make my own mini cnc mill / laser burner. If it works good, I'll upgrade to nema 23 motors with 2 Z motors and scale it up with a hand router. Using GRBL with open GCode Sender.
If anyone has better arduino cnc code/software. Let me know in comments or dm me. Gonna use MDF and plywood mostly to make frame.
Using 5/16'-18 threaded rod with the tee nuts to move the bed on y axis and the x and Z axix all from HomeDepot. Also for the X where the motor is on, I'll probably use a drawer slider as a guide also from Home Depot.
Gonna get some bearings from PrincessAuto.
How to use BenBox software for MakeBlock XY 2.0We would like to tell you about the functionality of the Benbox Laser Engraver, 3.7.99 (though a newer version may be already available). The laser engraver was ordered in China. No doubt, it is available for order on Aliexpress as well. It is delivered as a DIY constructor and it contains a circuit board developed in China, a 0,5 mWt, a frame (the like for every type of the circuit board and lasers) with steppers. Its program for this DIY engraver is in English, but it neither have any comments nor Russian translation.
Technical or software support is available only on Chinese forums. Now we’ll try to understand the engraver functionality to make Russian users’ life easier.Problems begin at the stage of the board driver firmware booting. In the constructor kit there are neither flash cards, nor discs with drivers.
The drivers can be found and downloaded on the official site of the seller on the Internet. There you can also read how to install them, but there is no explanation or translation of the buttons. But let us turn to the description of the accompanying program. There are two tabs.1. The first one is the steppers settings.
We used the settings found on the Internet. The positioning of the platform is precise, its motion is not as rapid as in a 3D-printer. However, when you change at least one of the variables, the platform starts to jerk and moves less accurately. We think that the parameters for the steppers windings are designed for low weight and speed.Let’s try to engrave a standard picture (a bird from the manufacture’s file) on a piece of cardboard. We’ll try to shorten the engraving time saving the quality at that, and try to see into the settings.SERIAL PORT transfers commands to the laser. LOW LIGHT INT and INTENSITY are laser exposure intensity (powers of the number two). SPEED is in mm/s.

TIME needed for the laser exposure in ms.CARVE MODE has the following parameters:1. SCAN BY LINE — engraving goes from left to right, then the laser moves to the next line to the left end position and again lead the line from left to right.2. Z-SHAPED — engraving goes from left to right and then from right to left.3. OUTLINE — outlining of the image contours.Then it is offered to select the exposure parameters: DISCRETE or CONTINUOUS. DISCRETE is engraving by shading.
CONTINUOUS is outlining without shading. But the difference between the modes is hardly noticeable.Engravings samples: 7 —Discrete, 6 and the others —Continuous. Their engraving time differs: The DISCRETE engraving time is 2-3 times longer.The SCAN BY LINE engraving is better than BY Z-SHAPED.OUTLINE has two more settings: POLYLINE and CURVE. No visible difference at all.LASER is laser engraving.
SERVO is pencil drawing. It is possible to fix a pencil in this constructor and draw with a pencil.Let’s try to laser engrave. Our task is to get a better quality result for a shorter period of time. SPEED is the laser speed (or steppers speed), It ranges from 50 to 3000. At the speed increase from 500 to 3000 the engraving time reduces by 30 sec.
TIME is the laser exposure time required for one dot. It ranges from 5 to 100.
