so with 100% infill I am still getting the diamond pattern in my ironing… thought it would go away as it was related to the support layer which is no longer present. going to try and change the shell infill from reticular to monotonic and see if that helps as maybe thats where the triangles are coming from ? still at a loss as to where they come from really.
and it happens on both my X1c printers… so doubt its related to the hardware.
as for the over extrusion oh the right… will solve that later think it may be related to the side of the print thats away from the aux fan.
the ironing on my X1C is patchy right now for seemingly no reason, I’m not sure if it’s a new firmware thing or what. I’ve got some stuff to print with 0.2 nozzle right now, but when I put the 0.4 back in later I’ll give your print a go and see what happens.
That’s a pretty significant revelation you just shared. That could explain a lot on many fronts. Have you tried an experiment where you simply disabled the fan entirely just for the purposes of seeing how it might affect the print? It’s worth a shot.
so changed my shell infill to monotonic (top and bottom monotonic line) and the diamonds went away hurrah ! Down to 14 top shell layers now and 100% infill on the part… so prints faster and Ironing was 40/40 at 45 degrees (straight lines). Doing a reprint now to be sure…
Also trying 30/40 on the other box as that gave me better results in the past and trying a spacer on the top glass plate of on machine to see if this helps with the over extrusion on the right - as thats the side way from the fan.
Actually seems it was the top shell infill more than just the top surface - looks like rectilinear causes the diamond ghosting I was seeing as it prints in random lines. Waiting on another print now to be sure.
Here are my findings: I also got the diamond shapes described by the OP. For me the infill pattern wasn’t the actual cause. Still I changed it to monotonic line:
The actual issue was the speed of the ironing. Too low speeds cause the diamond shape effect. I can’t explain why it happens though. I was able to fix it with speeds >45 mm/s. Notice that going too high with the speed may causes the print to look less even. Turning up the ironing flow >=25% causes some unevenness on the sides of the top surface so I stay below this value.
My surfaces look close to what you have in the right pic, without any ironing.
In fact I never used it as I saw no need.
What’s the size of those tiles? I might print one for comparison…
That my friend is an awesome revelation! I was not aware of that. Thanks for sharing your success with the group. I am certain that it will benefit all of us.
Hopefully it mean more users will realise that the ironing is NOT to smooth the top layer out but to create a fully fused surface.
Wouldn’t it be nice if we could add like a wobble effect as well?
Like for creating a shiny logo with a matte finish around…
Just a simple 30mm x 30mm x 5mm cube. Interesting that your surfaces are turning out that good without ironing. The look is one advantage. The other is that the surface feels very smooth which makes the part feel like it has a higher quality imo.
