extrusion multiplier very much depends on your machine (each prusa is different). I noticed that I had a slightly over extrusion so I reduced it a little.

did you previously run some kind of extruder calibration (like it was shortly implemented in firmware 3.0.10-alpha) ?
i think it'll be nescessary to do so.... otherwise we couldn't compare the settings and their behaviour between the different assemblies (or users).

best thing you can do is to extrude like 10cm of filament and check if 10cm on g-code is actually 10cm on the filament.

That being said I find that I get slightly better result with a pinch of under-extrusion when doing really fine details... but it also very much depends on the material. Unfortunately it's not a precise science, the "machinist" experience and hunch are still very important.

just started to play with S3D. gonna try the profiles from both philip and mateo.. printing using slicer and macpronterface flawlessly in PLA, ABS and PETG so far.. one thing that confused me there was the live z adjust.. on the printer using SD to get it closer to the bed I increase the negative value... I tried this in pronterface and first it had me pause the print.. OK. so I clicked -Z 0.1 a couple of times as 0.2m closer was what I wanted and it retracted more not advanced.. luckily I spotted in within moments and paused again clicked +0.1 four times and bingo.. I see S3D has same kind of z-adjust.. which moves the nozzle closer to the print + or -?
second question .. and the reason WHY I was using the z adjust in pronterface was live Z adjust disappeared from the options both direct and under tune on the LCD.. anyone know why? Is it because I'm printing from USB?

Another question ,.. just printed with Matt's ABS settings and blown away with the results.. if I switch to PLA do I need to manually live Z adjust? or is that in the settings somewhere.. when I was setting up materials settings in slic3r ABS and PETG were pretty much same z adjustment but the PLA needed the nozzle raising from -275 to -180 . I read this is because the PLA expands more as it's extruded from the nozzle so doesn't need so much squishing to make the layers bond properly.. can I set this in the materials profile for PLA, do I need to do it at all, or do I need to do it manually each time?

I do it manually every time. I believe it's impossible to make a one-config-to-rule-them-all, each of us would need a different setting and toying with the Z height could be dangerous!

@gary.h2

Live Z-Adjust disappears around when the first layer finished printing. Josef Prusa explains it here ( for older Firmware revisions): https://www.reddit.com/r/3Dprinting/com ... 2/d655nkx/
Not sure how Pronterface influences things, i never used it. I don't think it is meant to do live changes to the nozzle position during a running print, but I could be wrong..

With respect to alternating z-offset for different materials: you could try Process Settings -> Gcode -> Global G-Code Offset -> Z, but changing it via the S3D interface it is profile and not material dependent.

I'm not sure of this particular setting but many options can be set per material by altering the XML file manually

Worth a try. I wasn't sure either and didn't want to mess with it myself.

Hi,

@matteo.s2

Is it normal that with your FFF profile the "Auto-configure" drop downs disappear for selecting print quality and material ?
They are present with other Prusa i3 MK2 FFF profiles.

Thanks
