This card is used by me to check which size to design with when I need parts that slot together.
#Flux beamo series
The series of slots, squares, and circles, all have size increasing by 0.05mm. This is a cut done on 3mm thick plywood using the default preset settings. This should be an easy fix! Their tone suggests that it’s an improvement that’s under test and may end up being shipped by default. TMC carrier boards, SilentStepSticks, are a direct replacement to the Pololu boards that are installed in the Beamo.
#Flux beamo drivers
They offered to send me TMC2208 drivers that will fix the banding problem! This is excellent, Trinamic TMC drivers are the gold standard in stepper motor drivers right now. There are some very faint and regular horizontal lines that shows up, I am guessing this is an artifact due to the microstepping ability of the Y axis stepper motors, combined with some unfortunate floating point numbers in the tool-path.ĮDIT: I have contacted Beamo’s support staff.
I suspect a smaller, less intense job would keep the power supply much more happy. At 25% power level, you can achieve more detail but the laser power starts to fluctuate, some areas are darker than others. This shows that the 15% power level can achieve “ok” detail, and the laser power remains consistent. The images below are 20 megapixel! Click to zoom-in to see all the fine details! I did this cut at both the default 15% power level and then again at 25% power level to be able to get more detail. This is a very high resolution image, and at the “medium resolution” setting and default preset speed, took 1 hour. Starting with a giant etched image of the moon. Once you establish a workflow and figure out all the gotchas, a somewhat complex project like this is totally possible. This project demonstrates many cuts and engraving operations done in one go on the Beamo. It’s an Orrery, a mechanical toy that depicts the position of the Earth and Moon as they orbit each other and the Sun, with artwork showing the moon phases and Zodiac. Here are some pictures of example cuts and etches I did. Clean consistent cuts with straight and thin lines. My first cut was done on 3 mm thick wood, with default preset settings, and it did a fantastic job.
The laser was already pre-aligned from factory, and the cooling water tank was already filled. Connect it to WiFi, send over a file, and it did its thing. Out of the box, it worked, I didn’t even read the manual.
30W is still on the weaker end of the market, it means the cut depth isn’t very thick and the speed will be slower, but these are problems that can be mitigated or ignored. It also claims to be able to etch glass, and even stainless steel if you coat the steel with a special coating first.
Other “easy” materials like wood and leather it’ll have no problems with. The capabilities of the laser is supposed to be enough to cut and etch clear acrylic. It also advertises to be capable of 1000 DPI of resolution, meaning each pixel is 0.02mm, which is half bull****, the stepper motors are capable of that sort of resolution but the laser beam itself is larger (depends on focus and settings and the area of material being melted), all CO2 lasers are like this. It can also be upgraded with a “autofocus” attachment, and a rotary attachment. It has modern features such as a touch screen, camera preview, and WiFi. The workspace area is about the size of a sheet of paper, 300mm x 210mm. The Flux Beamo claims to output 30W of optical power at 10.6um wave length. I finally took the plunge and bought myself my very own laser cutter! It’s a cute little Flux Beamo!Ī small but modern 30W CO2 CNC laser cutter/engraver.
