Fuse 1 Down - She's DEAD - UPDATED!

Appreciate that but the new Fuse showed up today, set it up and loaded up some test jobs and it failed in the same way on our initial three attempts. Squeezed out a XY calibration test first but barely. Was seeing the same chunks and crumbling happening as on the old machine that started in December. The second and third full job attempts (our typical parts) both failed out before actually printing.

Fresh powder, totally cleaned out the powder trays and reset it totally clean between attempts and it’s again failing out on preheating with crumbling material on outer edges of “both” our chambers.

At this point with a brand new machine, I only see a few possibilities.

  • both chambers went faulty (which I find hard to believe at the same time
  • Nylon 12 GF has an issue with your latest firmware releases as this all kicked off immediately upon updating the old machine. (I find this highly probable with its timing. If I had to guess, it’s something to do with you fixing the chamber temp calibration setting and making it actually work)
  • Or I happened to get multiple bad cases of Nylon 12 GF (I wasted through over 12kg of powder…these last two cases were from the same order. I used two 100% jugs to test on both the old machine and this one so this is not a refresh ratio issue or contamination)

Those are the only three possibilities at this point.

I’d assume someone at Formlabs has tested the new firmware extensively with Nylon 12 GF…and I’d love to talk to them at this point or figure out that the past two cases of Nylon 12 GF I purchased were bad…

Either way I wish support could figure this out and actually get us going again. Having multiple support reps coming in and out of this situation is not helpful nor throwing us powder and a new machine.

As a person who oversees software development and whom is pretty good at bug hunting my own software… my gut is telling me this is a new firmware issue conflicting with Nylon 12 GF as it was running great for months prior to December but it could be two bad cases of powder.

It’s 1am…been at it all night and hopefully wake up to some ideas from your team tomorrow…better yet the actual engineer currently running Nylon 12 GF on a regular basis, on the current firmware, would be very helpful
