I have back problems and bending over in the enclosure of my A350, removing all the screws to fit the 4 aluminum plates for laser engraving, turned out to be a painfull job for the old guy. I simply bought an extra magneting plate and stuck the Aluminum parts on it with double sided tape.
Maybe i am missing something but it works for the engraving i am doing…
I also use that quick change attachment for Laser and 3D Printing - works really well. You just need to make sure you get a really good fit on the latch part. The author has multiple versions in the download so you can get this right.
I’ve only had my SM 2 A350 for 4 months and as yet haven’t even taken the CNC head out of the box so no idea how well (or not) the quick release attachment works with CNC.
