A question for the Fusion 360 experts

Paul/Andy any ideas?

My printer is out of its attic home and in the spare bedroom in order to print the NBR fish wagons for Rob. In the down time waiting for Rob to ok the test fish wagon I took the chance to print the revamped V1 brake body, with the results below. I have done 5 print runs since the mono came in from the cold, the test Fish - printed like a dream, the fish floor (twice) with a similar failure to that shown above but much closer to the build plate. Then another fish floor, printed perfectly and this V1 body.

After each failure I have drained and filter the left over resin and clean the tank and FEP with alcohol. Other than the first run (which worked) before each run I have used Paul's warm water- shake routine to make sure the resin is nicely fluid and the bedroom is nicely warmed but so what the ^%$£$ is going on, I'm fresh out of ideas.

 

Hi Andy its an almost brand new FEP and given the problems I have been filtering the resin before each print run, that's why I am very confused. Replacement FEP's have been ordered from anycubic so I will switch to a new one if/when they arrive.

 

Thanks Paul as always a myriad of possible solutions, I will try work though them but first I will replace the fep but as this is a relatively new problem as per Andys solution first.

 

Gents got any ideas what this is:

Screen captures from Chitu

Raft




Supports



Start of chassis



Then this what the ^&^%$%££" is it, it occurs half way through printing the chassis



Then you get the body




It prints exactly as portrayed by Chitu, its like there's a phantom raft or floor . I have check and all supports small. medium and large have raft Skate specified. I have even uninstalled and reinstalled chitu. I originally it was my fault but now I am completely stumped.

 

Rob,

as you may have guessed the print failed again!

 

Paul,

Sorry I posed a question without the background,

The stl is of a wagon chassis and body (but NO floor), it's Rob's fish mk 2 with improved strapping. Mk 1 printed without any problems.
The first couple of test prints had a rouge platform which prints almost at the top of the chassis just before it transitions into the body so I started experimenting in Chitu.

All I have done is open the stl then auto supported and sliced it, I would never dream of printing it. Then the first 3 screen shots are pretty much irrelevant, they show it sliced as expected, screen shot 4 is where the fun starts. The body starts at slice as a large rectangle and as you pass through the sliced reduces in size until it disappears after roughly 30 slices, there are then about another 10 slices of chassis before the body starts to print. I hadn't though of a visible plain and can't check as Fusion refuses to start, don't you just love cloud based software NOT. I can't do any further checks until it comes back online, grrrr. Your right about photo 5 I hadn't notice than, but it can wait till the big problem is resolved.

Sorry should have added, last night Rob sent me the F3D file and I gend the stl on my p/c, it had the same mysterious body, I also gend just the chassis and tried again - no foreign body. Frankly I am at a complete lost as to what is going on and am just stuck till Fusion 360 comes on line.

 

I completely agree but till Fusion 360 gets its finger out I cant check, and yes I also hide everything that I don't want on the stl.

I'm intrigued what that foreign object is on the last screenshot but again will just have to wait.

 

Rob,

I dont know if you have noticed but, on the original F3D you had 4 corner plates as saperate bodies, on the improved version there are only corners 2,3 and 4. No 1 has been added to one of the body panels, could that be the mystery body on screen grad 4?

 

Since Fusion came back to life at 9:0ish its been fine on my pc, but I also upgraded to windows 11, as usual every icon has changed and functions been rearranged, when will they learn if aint broke don't fix it.
