Notice anything wrong with this picture? That is because the Ortur had to approximate the steps. So if the machine moves 2 mm the controller sends 160 pulses. (Maybe it would be interesting to test out. 0125mm movement per step, AKA resolution. All the math equates to 80 steps per mm and that means. The LM2PRO has 1.8deg motors with 16-microstep drivers, GT2 timing belts (2mm pitch), and 20 tooth pulleys. Let’s look at some things I have observed while testing. It should allow faster burns with a more concentrated beam. After some debate, I want the smallest most focused spot. I already changed my mind and went anticlockwise. I still have to do a lot more testing before I commit to this. For the remainder of the tests, I set the lens focus to the clockwise position to have a uniform circle. Meaning the beam width is taller than it is wide. From these pictures, it is pretty obvious that the laser orientation is vertical. One key point to know is that the diode laser’s shape is not a circle, nor symmetrical. While I was trying to get my first low-power laser to work I did a lot of research on diode lasers. Then anticlockwiseīefore we continue, let’s talk about diode lasers. You can see in the grains of the dirt on the paint the real horizontal direction. Note my USB microscope was slightly on an angle with these pictures. Set my jig to that height and then burned a circle for a baseline. First, I focused the laser with the included cylinder. I’ll step through my process of calibrating it. I feel like I can have better repeatability. It is just a simple jig that completes a circuit when the lens touches the end of the M3 screw to illuminate the led. I got inspiration from my CNC machine and Z probe. I have a problem, I don’t feel like I can reliably focus the same way every time so I created a little focusing contraption. Let’s start first with focusing the laser. You can check out the initial unboxing and initial impressions in Ortur Laser Master 2 Pro laser engraver – First impressions. I can get into more details and share what I learned. I am going to break up the review process for the Ortur Laser Master 2 Pro (LM2Pro) into smaller bite-size bits instead of one long review.
