It’s called sharing… IE providing alternate views to the situation.
True - all lasers have to have their tube replaced which is why Glowforge should have baked this into the design from day one.
What is at issue here is @dan has not shared the COST of replaceing the tube. Is it $200… or is it $1000 or is it 2500? We don’t know.
Did I read his update incorrectly? The actual tubecost is unknown. It’s $499 for them to do the swap… but that still doesn’t explain what that cost is.
Combine the quoted time of 2years… and the unknown of the tube cost… and the unknown amount of work needed to do the tube swap. That’s the concern.
In closing; The laser tube “issue” was so trivialized in his update that I actually missed it the first time I read it. As owners we should all be concerned with this turn of events… because the bottom line is this laser we bought may be “disposable” in 2years. Are you prepared for that?
