If you have any questions, feel free to ask. LightBurn works very well with either controller. There is virtually no support for the board, but both the MiniGerbil and Cohesion 3D laserboard have excellent support forums that the manufacturers run. The MKS Sbase board is an illegal clone of the smoothieboard, and does not adhere to the open source licensing agreement of the smoothieboard. It is available at It runs either smoothieware, or GRBL-LPC, your choice It can control the X, Y and Z axis as well as a dedicated rotary attachment. It is available at Īlso, if you are thinking of expanding your K40 in the future with a powered Z bed and rotary attachment, the Cohesion 3D laserboard is also a drop in replacement for the K40. No need to wire up any new limit switches or mess with the wiring in any way. You say you’re having trouble getting consistent results, but that’s pretty vague - What kinds of problems are you having?Īnother option that is sub $100 is the MiniGerbil from awesome.tech It is a 32 bit controller running GRBL that has all the correct connectors on it for a K40 and is a simple 5 - 10 minute install. If you want to do surface marking, an 8-bit controller running Grbl 1.1f would be a better choice, and if you want to go fast, a Smoothieboard running Grbl-LPC is hard to beat. If you were using a diode where speed isn’t high anyway, or you primarily want cutting or vector scanning, you’ll get by with the ramps combo. Filled vectors work well because the gcode isn’t very heavy, but for images, where the dot density is really high, you end up with 3 or 4 gcode instructions per dot, roughly, and the throughput of the controller and the serial connection will limit you. Ich habe mit einer kleinen Zusatzschaltung vier pwm-Ausgänge mit entsprechendem Ausgangsstrom an den vier Servo-Anschlüssen des RAMPS-Boards erzeugt und versuche nun, Marlin die Dinger nahezubringen. The 2nd and 3rd points limit the complexity of code that can be processed. Sie erscheint beim Compilieren der Marlin-Software für einen Reprap-3D-Drucker. As soon as the power was connected, magic smoke started coming from the mega, so I. Uploaded the marlin firmware to the board via usb, then plugged in the 12v power supply. This isn’t an issue if you’re cutting or doing filled engraving where the system can use overscan and ramp up to speed outside of the cut. Hi, I just finished building my 3d printer using the arduino mega 2560 board with a ramps 1.4 board. The first one means that vector marking (getting a consistent line on a surface) is tricky because as the controller slows for corners it doesn’t lower the power, so you get dark spots at start / end points and sharp points in your shapes. No ramping of power output based on velocity of the laser head.Marlin isn’t terribly well suited for laser work for a couple reasons:
