I recently received some great Makita collets from Elaire Corporation in the mail. The only thing missing I felt, was a quick way of identifying their size. So I installed the laser tool in the BoXZY, and with the new 3-jaw chuck installed on the milling plate, went about laser etching size ID’s on them all.
I had to calculate the material height to include the chuck on the milling plate – as usually lasering is done with the build-plate installed. Here are my rough notes for reference:
BoXZY’s laser is not powerful enough to etch unfinished metal – it needs a dark finish to prevent the laser being reflected away – so I needed to coat the collet with something. First I reached for a dry-erase marker to colour over the area I wanted to etch, but although it lasered well, afterwards it wiped off immediately (in hindsight I really should of expected that to happen!). So instead I used a CD marker pen, which worked out perfectly.
I lined each one up in the chuck and loaded in my images with the appropriate size ID’s on them.
3 passes at 1% speed and 100% power got the result I was looking for…
