Issues with slicing embedded single line text
Hello,
I'm having problems with printing single line text embedded into an object. There are a few issues with Prusa Slicer that I submitted on GitHub nearly a year ago, but they were abandoned.
1. Both Arachne and Classic have their own ideas about extrusion width. Even though my font has a constant stroke width and I have a single fixed extrusion width set in slicer, the generators modify the extrusion width, messing up the letters.
2. Arachne is creating too short extrusions, so if you have letters 'H' and 'D', 'H' has a smaller height. Classic works correct in this regard, but it makes some parts of letters disappear completely.
3. And finally one of the most annoying things to watch, which also creates more stringing and random quality drop, is that the order of printing of embedded objects has no "traveling salesman" optimization, so the extruder is just running back and forth across the plate instead of going one letter after another. I checked that this issue is not present in SuperSlicer, but I guess Prusa is behind.

Since I lost hope for any help on GitHub, maybe you guys have some idea how to work around these problems? Maybe some of the slicer settings can be adjusted to make these issues go away? Thank you in advance for any help.
RE: Issues with slicing embedded single line text
I wish I knew of a solution but this — insert here the opposite of "optimization" — of the travel path seems more rampant now than in prior versions. It is indeed particularly irritating when the first layer contains text. I haven't found anything in PS that would allow one to adjust the path calculation.

RE: Issues with slicing embedded single line text
49 minutes spent on travel in a print. I don't know why Prusa is ignoring this for such a long time, while this is clearly an issue that can be fixed. It is working in SuperSlicer.

Unfortunately, I'm working on Prusa XL 5T, so I'm stuck with PrusaSlicer for now.

RE: Issues with slicing embedded single line text
One more question. Is there a way to set different acceleration rates per extruder/filament in Prusa XL. For the text, I need a very slow acceleration rate, but I don't want to slow down the rest of the print.
Currently, I'm just limiting text print speed with "Max volumetric speed" setting in filament. But I think I can go with a combination of higher speed and lower acceleration to get overall faster print and higher quality, as most of the quality issues are associated with starts and ends of the letter extrusions.
Copy/create a new filament preset and edit Filament Overrides and save it with a relevant name - eg., 'LetteringPLA'.
Cheerio,
RE: Issues with slicing embedded single line text
I can't find acceleration override in the filament settings. Where is it?
RE: Issues with slicing embedded single line text
I don't think there is an acceleration override in filament settings
There overrides are in Printer settings under advanced Mode

RE: Issues with slicing embedded single line text
But these are global limits. How do I apply different limits for each filament / extruder?
RE: Issues with slicing embedded single line text
Simple answer is you can't. Not really. Your volumetric flow rate on a per filament basis is the only thing you can really do but that wont effect acceleration.
RE: Issues with slicing embedded single line text
I think I read somewhere that Prusa team, since they got this cool 5 toolhead printer, is working on a big modification to the slicer to have a separate "Print Settings" per each extruder. Anyone got ETA on that feature?
