[BUG] Ugly seams

[Mikyner]

The seams look terrible and are very visible. On one of today's copies there is a gap instead of a seam (marked with an arrow on the photo)

I can confirm this issue on mk4 with fw 5.1.2 and prusaslicer 2.7.1.
first I thought it is an input shaper issue but I looks the same without input shaping

Seams are likely more to do with the slicer than with the firmware, so maybe have a look at the PrusaSlicer issues on GitHub.

I will draw your attention to two requests for the same feature: seams that can be nearly invisible. prusa3d/PrusaSlicer#11621
prusa3d/PrusaSlicer#11948

You might like to give the post-processor script that is linked in the second of those posts a go. In any case you might comment on those pages to give them a bump.

This is a duplicate of #3286

Maybe just close this and comment there?

[Mikyner]

I confirm that this is a bug in Prusa Slicer and not in the printer FW

Same here. It's a disaster. MK3 never had this issue.

Same here. It's a disaster. MK3 never had this issue.

It's a slicer problem, I'm using Orc

[Mikyner]

It's a slicer problem, I'm using Orca now and everything is fine.

I think just close this and refer to prusa3d/PrusaSlicer#11914 ?

Exposed and obvious seam lines have been with Prusa printers for a long time.
Now, both Mk4 and XL printers have finer steps it ought to be possible to at least reduce the seam gaps somewhat by way of the higher accuracy of movement.
I have never seen a rational reason given as to why we must tolerate them.
If prusa saw fit to spend huge resources fixing resonance aberrations with the IS thing, the seam lines ought be worth at least as great an effort since the impact is in fact much greater.
The open seam lines not only look bad, they weaken the print too.

[MichaelJLew]

Try the latest development build of OrcaSlicer. It has scarf joint seams that fix many seam issues.

Thanks for the suggestion. Buuut… I’m of an age not to be constantly trying new products, preferring the safe road. If Orca can fix this issue why not Prusa ? Sent from Outlook for iOS<https://aka.ms/o0ukef>

The fix is in Orca, not yet PrusaSlicer. Use it or don’t. It’s not that you are too old.
