They can replace the tube, in fact that’s what they used to offer as a service and they guaranteed that it would be a $500 charge. They have since discontinued that policy and program. It’s faster, easier, and less expensive for you to ship them your machine and have them ship you a refurbished machine.
Notice I said less expensive, but it’s often not clear why it’s less expensive or for whom.
We can look at a couple of cases. It’s worth mentioning that I’m speculating a little bit here especially for analysis of Glowforge’s end of this deal. They’ve never really told us why they do things in general, but we can assume that everything they do is in service of keeping the business viable and making a little money — that’s the purpose of a company especially when they have investors like Glowforge does. They’re not a charity.
For Glowforge? Absolutely it’s less expensive. The problem here is logistics. If they support via refurbished machines they can have machines ready to go. They can cross ship them to you, which is better for customer service. There are fewer unexpected complications compared to what happens when they get a returned machine that has been modified or has secondary problems that they have to troubleshoot and fix while replacing the tube. This is all fixed by having a reserve of machines ready to be shipped back to customers, having slack in the system is key to keeping things moving smoothly. Queue theory in action.
For a business user? It’s much less expensive this way. Downtime is a huge problem and in the old model you would have to ship your machine to Glowforge, they would work on it for some period of time, and then they would ship it back to you. It would take upwards of about a month. Now with cross shipping your downtime could be two or three days depending on where you live. Try asking somebody who makes a living with their laser how much being down for 30 days in November would cost them. They’ll take cross shipping every time.
For a hobby user? Surprisingly I still think it’s less expensive. Out-of-pocket, yes you pay more than the original $500 price point for a tube replacement. However this doesn’t take into account that you’re effectively getting a new machine and the clock resets on all of the secondary problems you might have as well. It’s really hard to figure out the value of that, but if your tube is going chances are other components are starting to have some wear, especially moving parts. I can’t prove it exactly but I would suspect that it’s a net positive even if it cost you a little more out-of-pocket.
Don’t get me wrong it’s frustrating to deal with support and it’s frustrating that the refurbishment process is a black hole — they don’t price it per machine, there’s kind of blanket tiers of costs. Even with that I think that their current system is probably better for most users and it’s definitely more sustainable for them than what they were trying to do before.
If you really want to repair your machine and not ship yours to Glowforge you could always go with Wiregrass. You can search the forum for more info about them. There are cases where Wiregrass probably makes a lot of sense. For example if you have a pretty new machine that’s just out of warranty and you crack a wheel that isn’t user accessible, Wiregrass can probably help you out. Or in the case where you’ve modified your machine such as by cutting out the fan in the rear… Glowforge doesn’t want to deal with people‘s modified machines, and you may be ineligible for repairs in the first place. I don’t know if Wiregrass has the same policy.
Wiregrass also sells some repair kits so if you are feeling particularly handy and not afraid to dig into the internals of the machine, you might be able to repair whatever problem you have. This is particularly relevant in the case of a red wire short, as far as these things go it’s a fairly easy fix. It’s worth looking into depending on what your problem is.
And lastly you might be able to hire a local electronics expert for some hardware problems. I know someone in the UK who had the red wire problem fixed by a local electrician with a little coaching from me.
Anyway that’s probably more than you bargained for but there’s some context for you.
