Stringing: question to Slic3r Prusa edition software engineers
No amateurs speculations here please I'm fedup of that
How can you Prusa software engineers explain that with the same out of the box settings : retraction length 0.8mm and retraction speed 35 mm/s the Cura ( MK2 setting ) and the Slic3r Prusa edtition has completely different outcome when doing the stringing test ( see picture ) .
Obviously the Prusa MK3 hardware is good but the slicer software is not on par.
Did you Prusa software engineers make the stringing test before releasing your software ?
Best regards

Was this true apples and apples? Same temperatures, same print speeds, same perimeter speeds, etc?
Re: Stringing: question to Slic3r Prusa edition software engineers
Even if you take the same settings, the slicers differ. For example in the way they calculate the needed filament length. If you compensate for that, you get another extrusion factor.
Another point where they could differ is that some slicers only issue retraction commands when the head moves a greater distance. So if your distance is set too high, no retraction happens and you get stringing.
In the baseline: You have to dial in your printer per slicer

You've come to the wrong place then.

And?

LOL. Amazing Rob!

I've owned a 3D printer for 6.5 months. I am a pro.
As mentioned above, there's literally a million and one variables to account for.
Speed.
Minimum Speed.
Way minimum layer time is processed.
What version of Slic3r? The new one compeltely changed the way minimum layer time is processed.
What version of Cura? This is relevant to what you are talking about.
Do they both have the same extrusion multiplier.
Do they both have the same extrusion width.
Do they both have the same "rounding"
Do you have any of the advanced extrusion smoothing turned on in Cura?
Do you have the same infill density?
Do you have the same infill pattern?
Do you have the same infill algorithm? (No, you don't, because they are different programs)
Do you have the same premiers?
Is the perimeter<->perimeter overlap the same?
is the perimeter<->infill overlap the same?
I could keep going on all day. But if you seriously wanna humor me, try and answer all of those. A few of those are hard coded in Slic3r though, so you may need to read a bit of code. I'm sure I can think of more differences in the meantime for you to check.
TRAVEL speed.
Jerk and acceleration settings in pre-print gcode.
PS: I used to work in maintenance.
Hi, I'm Sean. I used to work on CNC machines.
I try to not make mistakes, but the decision is YOURS.

You got the wrong printer. This is an amateur printer with a quite OK price/performance ratio.
You want professional level performance - get a pro printer with maintenance contract.
For my part, I also would prefer a higher level of quality, but one has to be realistic. I talked to a workshop guy recently, they have two pro printers (40k and 100k price point) and a yearly budget of 40k for print materials.
Or check out UM. They just launched a new machine at $5k IIRC.
