First off, thanks in advance for your help. I just found a Facebook marketplace listing for an ACRO 1515 for $250 with all of the motors, electronics etc. included. So of course, I jumped on it. It turned out to be a great deal because he also included a ton of linear rail that he had used to build a table for the laser engraver. I think I ended up with all of the ACRO system v-slot and then probably 10 1500mm lengths of other 20x20 aluminum extrusion, which I plan to use to build an enclosure rather than a table. No matter what, I think I came out ahead, but the laser and controller are older and not powerful enough to cut through anything thicker than 1/8 inch (6mm). I found a more powerful laser today on Prime Day for nearly $90 off. It is a 5w diode (yes, I know a CO2 laser is stronger and better, but more than I wanted to spend today). this is the laser I bought, and I added a 24v 15a power supply for $20. so all in all, I'm in for $165 on the laser and power. The Acro is currently running on a xPro v3 controller, so I will need to upgrade that (I think). The question is, what do I need to get to fire the laser? It has a 3 wire connection on the top, so I'm assuming that the laser driver is built in to the laser and all I need to do is send it PWM, power, and ground and that will work, right? I have an SKR 1.4 turbo that I think will work for that, but I am just not sure if I need another laser driver in the middle or if I have everything I need. I would love to run it off a Blackbox just from an ease of use perspective because that's what is the brains on my CNC. But if I can save some money by using parts I already have, that would be ideal. Thanks again for your help.
