Hey I'm having a few issues with my laser cutter and if anyone can help me solve any of these I would be very grateful. So just to start off, i've been following this guide here: openBuilds FreeBURN-1 V-slot CO2 Laser (60-100w) It basically stops giving direction after the mechanical stuff is built though so i've been trying to figure out the motors and the wiring myself. The problems I'm having involve Nema 17 and Nema 23 motors, DQ542MA Stepper Drivers, and AWC708C Lite Laser Controller. I've hooked up everything and already troubleshot several problems, but I'm still having a couple issues: 1. Somehow my Y axis is not calibrating properly somehow or something? I start a test cut and by the time it finishes, the laser head is about 5cm higher than where it started. Does anyone know why this is? 2. For some reason I can't figure out which direction the motors are supposed to turn. Like, how I initially set it up, the arrows on the controllers all matched up with the directions the laser was moving (left moved the laser head left etc.) BUT, when I did the test cut, the image was flipped left from right. It was still right side up, but flipped left and right. So I switched the wires and now it prints correctly, but now the left key moves the laser right, and the right, left. -_- Oh, and initially, the origin was set to be the top left corner of the space, and after I switched things, it became the top right corner. What corner is the origin supposed to be? Does anyone know what could be going on here? I'd really appreciate any help or insight anyone could give me. Thank you very much! I can upload a video or pictures if that would help. Let me know. Thanks! EDIT: Oh one other thing I thought I should add; I know that the calibration is off and its not just supposed to end up 5cm higher because if I try to move the head manually with the controller after it finished, the bar crashes into the side of my apparatus because it thinks the origin is 5 cm higher than it actually is. Its extremely frustrating.
