Laser Engraving on My Kossel Clone/ Expanding My Build Area

[ABearden]

Check into the magnetic ball joints. I've seen a few people complain about them popping out momentarily during operation and causing print artifacts (just riding up then reseating). Given your love of printing at 300mm/s, I could see that happening. Could be they just didn't have them lubed appropriately, but something to look into before spending $40 on arms. Another option would be to design a swappable head. Mount the laser and the hotend on similar inserts then have them twist or click into place on the platform.

As for an enclosure, that should be easy to do for a delta. Try it with hotglue and cardboard first; nice and cheap. Hobby boards are similarly inexpensive at Home Depot. Usually around $5 to $10 for a 2' x 4' section. It's the spiffy acrylic enclosures that are expensive.
