Hi, I have a question. I have a soluble support fillament from spoolworkslabs. the print speed is 50mm/s for this spool.
I cant seem to change that in the AMSlite settings for just this spool. Do i need to print everything at 50mm/s ?
i will use this fillement purly for support interface. so that is set on 50mm/s
Welcome to the forum.
The speed of printing per filament isn’t controlled by the AMS. It is controlled entirely by the settings you have for that specific filament in Bambu Studio.

thnx for the fast reaction.
i see the max volumetric speed. not the mm/s
this is not the same. is there a way to calculate that?
Switch from Global to Objects, click on the part you want to change & the settings will show on the bottom.
@JonRaymond was quicker 
Volumetric flow through the nozzle must be equal to “Line width” * “Layer Height” * “Speed”. Otherwise, over- or underextrusion will result.
So you can quickly calculate the flow rate to set for the filament as a limiter.

whats the difference compared to flow dynamics calibration ?
i would of assumed if you have a print speed its already based around the max volumetric speed or could be calculated by the flow dynamics calibration
Good question. In my view, the flow dynamics calibration would apply equally to both nozzle exit flow and deposition, so it takes care of itself and the calculation works without it. The really interesting test would be a max flow test though. Looking at spoolWorks Scaffold Filament - 1.75mm - 500g | YouPrintin3D, there’s no max flow given. Only the 50mm/s speed (like in pre-High Speed times 
). I expect that was the initial problem leading to the question.
@B-Jay : I have never had much luck with PVA myself. But BVOH from Fiberlogy worked like a dream for PLA. Not so much use for it now though since discovering PETG for PLA and PLA for PETG and more.

I looked on the website too , i was going to try and compare it with b labs which has print speeds of 200-100 mms dependant on which is purchased and what its used for
after the inital thread subject changed

Yes, this was what raised the question!

this looks promising
