This evenings progress, modified the work holding a bit for more orientations. I now feel confident that I can fixture anything I need current but also put the machine where I need in the workspace repeatedly. Next job was chasing the laser focus... the manual focusing of the laser dot is super difficult by eye and was regularly off. So began 3 hours of chasing my tail after 1mm variance in the focus. In the end I settled on a 0.03mm feeler gauge to set the touch off followed by a 3.5mm drill bit to set the final laser head clearance on the actual part. Results so far are much better at 50% power, excellent detail!
