Very familiar with planned obsolescence. There’s a really cool documentary on the lightbulb cartel, and how they bilked the world for decades. Highly recommend if you haven’t seen it.
Anyways, It must have autocorrected it to opalescence lol. Sorry didn’t mean to call you out, I was just intrigued by the potential of that meaning something that I wasn’t aware of
not unless we have a request and the con is willing to pay our travel (we have to drive to every con due to i have a backpack that is not allowed on airplanes and i do panels at con’s with two penny farthing )
Could it be related to the fact that the head’s at risk from fire/smoke compared to other parts? Maybe it’s just a good move for cheaper repair down the road in case of accident, rather than yet another “consumable”?
You know, if I could alleviate the need to buy something like a Cricut® Cutter by slapping a simple knife head on my forge to cut vinyl stickers since I can’t laser them, I’d be a pretty happy guy down the road. That, or making ink drawings by holding an actual pen/pencil type tip …
3D extrusion is a little less interesting to me in a forge, just due to the height limitations of the bed.
there are parts of the head that will need to be clean such as the lens and at some point the lens may need to be replaced. you are creating dust and smoke as you engrave. and the laser puts energy that takes the form of heat and that passes through the glass lens they can be marred by the beam and heat may cause fractures in the lens having it removable makes it easier to do things like clean and or replace the lens . my Large laser at work has a removable head, as at least once a week we clean it completely.
That makes a certain amount of sense – even if it’s not a consumable, we would all be happier cleaning the heading without being head and shoulders deep inside the machine. (Although I do wonder a little about the repeatability of head position after removal and replacement. You might lose a few mils that way.)
