After a lot of search and research. I haven’t found any information that points out to a current error on my Fuse 1.
I have already contacted support with this issue, but now asking to the community.
As suggested by support tests were conducted, with and without filter being the pressure a little higher without the filter, the filter is brand new, and maintenance was conducted recently by our local dealer.
Our local dealer states that this is not an issue at all and that the machine can operate normally even with this issue present.
We are about to run production of 800 parts so I want to be sure no issues will arise during this upcoming project.
Id double check and make sure the intake filter was changed. When I had this error I vacuumed off the intake filter and that solved it, then changed out the filter.
I changed the filter myself, it’s brand new. I conducted all the cleaning including the exhaust line using a super large brush and a lot of laurolactam was removed.
I have the same issue. The pressure error was present after vacuuming and blowing out the dust from the filter, even though I had removed the filter. The print came out with no issue with the error presented. It seems to me it might be the sensor damaged.
Did anyone at formlabs or reseller offered a solution for this? This machine has more than 1000 hours and almost half of it has been running this way with “no issues” . Do you have any idea of which sensor is faulty?
Hi all - thanks so much for sharing your situations here and we’re sorry it’s happening. We’ve been discussing this error issue across our Engineering and Services teammates and they’ve asked if both @Mario_Martinez and @Rosco_ME can open a Support Case so that they can learn more unique specifics about your printers in hopes to solve this quickly. Thanks for your patience!
I’m jumping into this discussion a bit late, since I just received a pressure warning for the first time during the self-test phase. Although I was given the option to select “Ignore” when the message appeared, an error doesn’t just go away just because you ignore it.
Here’s what I’ve done so far:
Cleaned the exhaust filter
Cleaned the exhaust line with a long wire brush
Cleaned all the door seals
Used a different build chamber
Replaced the intake filter with a new one
After each step, I tried priming the printer again, and each time I got the low-pressure warning.
After replacing the intake filter, I noticed that even though the maintenance door was open and the filter had been removed, all the fans were still running. However, the Formlabs support video on the filters mentioned that the fans are actually supposed to turn off automatically during this maintenance step.
So I simply turned the printer off, waited 5 minutes, turned it back on, waited another 5 minutes, and ran the self-test again.
Sure enough, I was now able to prime the printer successfully, without any error messages or warnings.
I’m now going to start the next print and see if it completes successfully. I just wanted to document this here for the record. (By the way, the intake filter had already been in use for 1 1/2 years—just for your information.)
@Mario_Martinez
May I ask if and how you were able to fix the error?
No Solution @CARLAYERS, from anyone. Nor users or support, the machine just works and you know if it works don’t fix it :v
I do clean more frequently than the advised on the maintenance routine. Surprisingly about a month ago the machine passed all test without the pressure alert, It wasn’t recently cleaned so very weird, machines right?
Can’t you see those pressure readings in the logs? Last this happened to me I believe I could see them but I’m not certain.
I too have had oddball things occur, and a shutdown/restart has fixed them. It’s probably not a terrible idea to shut our printers down every so often.
I have found that if FUSE1 is not rebooted regularly, it will throw a random error that rebooting resolves.
Since I started rebooting the printer once every week, I stopped getting these random “errors”.
Now the only errors I get are due to aging powder which is solved by performing a full refresh of the hopper.
I turn off or reboot mine, only when she decides to not recognize that OMM mode exist and asks for a powder card when the menu doesn’t even exist and by placing it nothing happens.
A quick update from me: The print job following the error described above completed without any issues.
The next print job after that also went off without a hitch. Priming the printer wasn’t a problem here either.
I’ve noticed a few “mini freezes” on the display a couple of times when our Fuse1+ was inactive for a long time without being restarted.
I think I’ll start simply turning off the Fuse after every print job. Since our Fuse doesn’t run every day—but mostly over the weekend—this won’t be any extra effort for me.
Especially since, even when the Fuse isn’t running for several days, an internal fan still runs continuously. In this case, it might actually be better to prevent potential fine dust from being sucked in all the time.
In summary, I can say that if this issue occurs, a simple restart might be all it takes to fix it.
