Preform/Dashboard Bug cutting Fuse Print Job in Half

This has now happened a few times with this last print really starting to annoy me… especially when trying to print a taller part and it cuts it in half ruining the job.

So here is the sliced print and as you can see this is a 15 hour and 42 minute print

Got a notification not even 8 hours later saying “Print Complete”… (Note: before this the Timeline showed that the print would take up until 4am…then all of a sudden “Print Complete” and the timeline bumps back to where it stopped and acts like everything is “Good to Go”)

No error message…no Abort… just a “congratulations your print was a success”…

Again, very annoying as the taller part was cut in half and these are the kinds of things that has stopped us from printing larger parts in the Fuse versus smaller rows of parts. The risk and the gamble is just not worth the reward…

But back to this issue…

The print bed looked fine up until this point with no indication of any problems. Even if it did… it would be nice to be alerted with an Error or an Abort versus just a “Print Complete”…?

I had this and rolled back the firmware one version. There is several issues with the latest firmware. Such as the printer lets you open the enclosure as soon as the printer is done. No wait time for cooling. Then another where the print starts, then stops totally random somewhere during the print and confirms the print is done in Dashboard but no message on the printer.

Already kicked off the same print a second time, will see how it goes, but will definitely roll back Firmware after this.

Hopefully Formlabs acknowledges this bug and fixes it.

Well looks like they went and fixed a bunch of these bugs… :crossed_fingers:

Hi @LEADNAV thanks for sharing to the community - Apologies for the inconvenience, our Engineering team confirmed that indeed it was a bug and was fixed. The issue was that Fuse firmware 1.21.0 does not show customers error messages when the print fails to complete. This has been fixed in Fuse Firmware 1.21.1, released January 15.

Since support told me my recent failures were from “underdosing”… it would be nice for you to make “doser offset calibration” work when using Legacy settings.

Was told this setting does not change anything when running Legacy settings for some reason… and after weeks of support was told to run Legacy settings… so just saying…it would be nice to just make doser offset work when running it

She’s Back… Just had a random “Print Complete” at only 2 hours in to a 6 hour print… Started cooling with a “Congrats” jobs done…

We all seen this before so Formlabs…please kill this bug again.

Just lost another $200 in material + labor. The gamble we play with SLS and this system unfortunately… :-1:

Was running fine the past few weeks prior at least.


Not again… :confused: I guess they ran out of bugspray for real this time.

So after the “Job Complete now Cooling message” it waited 2-3 hours after cooling to give an Error/Abort report with photos.

In the photos one photo looked under dosed but then the rest looked fine minus in every photo that dark smoke cloud dead center of chamber/camera. I almost thought the smoke caused it too abort thinking it was a cracked powder bed… but not sure why the one photo was underdosed as everything looked perfect when I opened the door.

Powder was fine no blockages.

Support suggested up’ing the dose offset to +5 from the +4 I have set now.

Side note: If you look back at my other thread where I was having print issues in Nylon 12 in Default and speed settings…it was determined I needed to run Legacy to get quality parts and part edges. With that Support, very confidentiality pushed that the “chamber temp offset” and the “doser calibration offset” DOES NOT do anything when running the old Legacy settings…

I found this hard to believe as I argued repeatedly that changing bed temp offset in Legacy in fact changed my chamber temp… finally the support rep acknowledged that he double checked and “Yes, chamber temp offset DOES work in Legacy settings BUT it DOES NOT change doser calibration offset in Legacy”

I actually wrote back a fourth arguing this fact but they insisted… to the point I put out a thread suggesting that they make doser calibration offset work in Legacy settings.

Jump forward to this weeks issue… they suggested I “up Legacy doser offset to +5”…when I brought that fact up they sent this

Since your original case we actually did some internal testing as far as what adjustments can be made with legacy settings. Contrary to what we’d previously been told by software, we found that adjusting offsets actually does adjust printer behavior. This may not be a surprise to you, since you have been having success for a while with a 4° dosing offset applied. If you encounter underdosing again, please try increasing the offset by a degree. If needed, it will make a difference.

This has been the extremely frustrating thing when it comes to support…as it seems they honestly do not know their own systems as much as we do…

Ran the same job again and it was fine though and has been running fine for the past few months so I will just chaulk this up to a random doser issue.

This new UI though…where it says “Good Job Print Complete”…then waits hours till after it’s cooled to give you the “Abort Error message”…I think needs to be reworked. I always remembered getting the Abort/Error message immediately/first…this new update makes it confusing.

Why not rollback to the latest working preform/firmware combination. We ran into some issues also, and after the last rollback everything back to normal, is this a Fuse1 or Fuse 1+? It seems Fuse1+ is quite problematic with PA12 sometimes from what I have been reading lately.

My only weird issue recently was that the machine never recognized , it has finished(<1 min for almost 2 days was the status on the dashboard) but when I launched the next job yesterday the dashboard updated and so far so good. Have you checked the UPS?
