Fuse 1 Quartztubes

Has anyone experienced issues with the quartz tube assembly on their Fuse 1 printer?

We are experiencing low output on both quartz tubes, but never at the same time. I can proceed in Preprint if i ignore the warning, but the printer does not exceed 140°C.

Has anyone else encountered this issue?

We switched to a new quartz tube assembly but the problem persists. So im guessing its deeper down the rabbithole.

P.S
I should note that these errors should NOT reflect badly on Formlabs as this machine has been taken out of commission as it has well over 10k hours on it and is no longer supported by Formlabs.

This is the first machine we bought and it has served us incredibly well over the last 3 years.

We will be scrapping it for parts, but a piece of me still wants to get it running. :smiley:

Perhaps a power supply issue?

Hey @SMute
Yeah im beginning to think it might be something related to that seeing that im getting errors on both tubes but never both at the same time.

If it were mine that’s where I would look, or at least in that direction. Since the bulbs presumably draw line power I wonder if it could be a relay somewhere in there going bad?

They are truly sensitive to electrical variations, I’ll test everything on that side.

Hey @Andreasemilsson

I’ve reached out through our support system, even if ther was some deal to let you keep an obsolete printer as spare parts, maybe I can give your logs a quick check and give you an idea in which direction to go when troubleshooting this printer.

In general this should be the way for most troubleshooting processes with issues like these. The first thing to check would be electrical as mentioned before, I’m thinking less of the quartz tubes themselves, but more of the RTDs checking the reported temperatures being affected by electrical noise.
If we can put a checkmark behind that, I’d personally check the quarts tubes themselves and replace them with each other/new ones (remember to wear gloves when handling quartz tubes).
Next on the list would be the RTDs in case we’re always getting the error on the same side and then troubleshooting would go for the quartz tube frame or power supply, according to what we’re seeing in the logs.

In any case, issues like these can be pretty complex, so checking what is going on with the various sensors involved and what they’re reading can narrow everything down pretty quickly.

Kind regards
Jakob

Will try your suggestions as mentioned in the ticket.

Have a great day.

For those interested in what the next step is i will be replacing the heater as it struggled to even reach 175 degrees celsius. thx to @Jakob_D for checking the logs. You are a legend my man.

I was interested indeed! So you fuse will probably keep running for a while, amazing.

Awesome to see this printer might live to print again. Maybe another 10,000 hours?

hopefully yes, but only time will tell. Hopefully i will have time today to tear it down again and replace the air heater.

haha another 10k hours might be stretching it. :rofl:
