Help with increasing travel speed on MK3S+

I have been trying to increase the travel speed for my MK3S+ machines, so that it takes less time when it is moving across the build plate.  It seems like no matter how high I adjust the travel speed in the speed section of the print settings, it doesn't move very fast (it feels like it's about 100mm/s travel).  Is there another place where I need to adjust settings to get it to move faster?  And just to clarify, I'm printing at about 70mm/s, I just want it to move from one object to another faster, and can't seem to make it do that.

Speed settings are the maximum permitted.  You will only see top speeds when the parts are a long way apart.  You may like to try altering acceleration and jerk settings but take note of the defaults first.

Cheerio,

RE: Help with increasing travel speed on MK3S+

There are the machine maximums set under Printer Settings>Machine Limits.  On a default MK3 type profile they ares et to 200mm/s for default and 100mm/s for stealth mode printing.

Then under Print Settings you have the Speed>Speed for Non-print moves value.  That looks like it is set to 180mm/s on a 0.4 quality profile.  When I slice 2 objects spaced apart the preview is showing me travel speeds of 180mm so that looks like its behaving normally.  (this is with 2.4.2 btw).

There is another speed setting for Autospeed which on the profile is also set to 200mm/s but thats only used as a max when your print move speeds are auto (set to 0) in which case the max volumetric from the filament profile is more likely to be the limiting factor.

I'd suggest saving a project from Prusa Slicer (File>Save Project as) and then take the .3mf file produced, zip it up and attach the zip file here.  Must be zipped or the forum wont accept the file.

With a project we can look at all the settings and see what is the limiting factor.

Even when it's moving all the way across the build plate, it still moves relatively slow.  I'm going to try running it outside of stealth mode and see if that changes things.  I believe I've changed all of the values in all of the places listed above to 200mm/s or higher, but maybe it's just that stealth mode won't let it get up to those speeds.  I'll experiment a bit more, and see about uploading a file.
