The JTech 4.2W laser option is a great addition to my Axiom AR6 Pro+ which I have had for only a year. I previously would only route out the designs, paint, sand off the paint and then finish. I still do that style, but this tool allows for a different price point option which my customers love. Instead of simply cutting, then painting (wait a day), sanding and then spray finish (wait a day) sand and final finish (wait a day)..... I can burn, cut and finish on the same day, then light sand and one more coat and done! That compresses the schedule and reduces the shop time makes for a less expensive option for your customer.
My next suggestion here comes from trying to burn and cut concentric circles. Initially you will need to find your exact offset center from spindle to laser. The suggestion in the manual, which is close, was 80mm offset in the Y axis. My actual offset was 79mm in the Y axis and -2mm in the X axis. For me. this yields perfect registration between the spindle 0x,0y and the laser 0x,0y and is spot on. Now combine the cuts with the burn for some excellent creative results. Remember, if the 0.5mm movement in the fast spindle mode doesn't yield exactly what you need, the slow mode offers a smaller increment when trying to find that perfect registration. Write it down, Best of luck... hope that helps.
I agree with your comments, Riccibobbi. I, too, are relatively new here - had my Axiom since February. I, too, found that my laser was not offset exactly as in the manual. My offsets were 81.800 and 3.000 on the Y and X axis, respectively. Point for others is, as you said, is to determine this yourself for your machine.
BTW: I used the same basic technique for setting the center axis (Y) for the rotary tool. Although it can change when I reinstall and I have to recalibrate, once I determine the offset, I can reproduce it by setting the automatic HOME, setting that temporarily as the Origin X-Y, then "dialing in" the Y offset that I have determine. Then it is easy to determine where I want the X to be, and then set the Origin X-Y.
