So I did my first ever 3D print
It's been pointed out that the print isn't quite good. While I'm pleased with it (because I had no expectations), I want to do better.
For reference, I just printed the default cube in superslicer with no setting changes. I'm using formfutura reform rPLA

- do you have fuzzy skin enabled?
- what's the temperature/cooling/print speed/minimum layer time?
rare-sapphireOP•2y ago
No to fuzzy skin.
Extruder first and other layers is 260
Bed first and other 105
Fan at default speed is checked and default fan speed set to 12%
PLA at 260?
rare-sapphireOP•2y ago
I didn't know it needed changed, mate. I should have read the instructions on filament. I'm just realising that.
Print temp: ± 200 - 215° C, Heat bed: ± 50 - 60° C
lol
105 bed for pla? 
are melting the PLA with the bed
are melting the PLA with the bedyou probably want to go on the high side of that for v-core speeds
more speed needs higher temp with more cooling
rare-sapphireOP•2y ago
so 215 and 60
I'll bash out another print and while it's printing I'll read that guide @mitsuma posted (thank you)
which filament profile did you select?
asa or abs?
rare-sapphireOP•2y ago
I didn't select anything. I was excited about my first print. Ok, we all know where I went wrong here 🙂
I'm just asking to make you aware that superslicer has separate tabs for print settings, filament settings and printer settings
rare-sapphireOP•2y ago
No, I know. I was just making fun of myself for being over eager.
but I think your next print will look good 😄
rare-sapphireOP•2y ago
Does changing the filament type automatically change temp?
the filament profiles include temperature settings
rare-sapphireOP•2y ago
@elcoj I did use an ASA profile. Hopefully this next print will be much better. Thank you

Guessing the noise from the fan isn't meant to happen? It's 32% through and it's made this noise the whole time. Didn't have this on the first print.
That's very noisy for 32%
You are printing very slowly. High minimum layer time?
rare-sapphireOP•2y ago
it says 100%
Probably because it hits the minimum layer time. Check the slicer settings
That's a bit much
rare-sapphireOP•2y ago
That was the default for PLA
Change the settings level to expert
With a 4028, you shouldn't use 100% at normal speeds
You'll want to decrease the short layer time, 4s or something. You'll need to unhide the advanced settings.
rare-sapphireOP•2y ago
That's the new print. bigger cube and it decided it was 100% done when it completed the z-top.
getting better
I think it is probably overcooled, so change the cooling settings and try again
I also prefer to use 0.5 line width to have a bit better layer adhesion
did you sink it into the bed by the way in the slicer? the bottom is missing
rare-sapphireOP•2y ago
I see exactly what you mean about my first print. It is bad 🙂
rare-sapphireOP•2y ago
@mitsuma I'm trying to follow the tuning guide you sent me and am currently doing the extruder calibration. There's no rotation_distance in printer.cfg so I'm not sure how to do the calculation required.
Incidentally, it pushed out 100mm as expected.
roation distance is in the config, its just in the nested config
you would need to add an override where you just repeat the config part in the printer.cfg
rare-sapphireOP•2y ago
Right, I see it now in config/extruder/lgx-lite.cfg
dont edit files in the config folder
rare-sapphireOP•2y ago
Nope, not editing it. I remember you told me this a couple of days ago 🙂
I just opened it to check the value.
I really don't want to bore people with my very basic questions. I'm sure I'll have a lot of them while I get to grips with learning. Is there a newbies guide to 3d printing specifically for klipper that you would suggest?
I would leave rotation_distance a the default and just adjust extrusion multiplier for each filament, you need to do that anyway
rare-sapphireOP•2y ago
My bed leveling test didn't go great. I've attempted calibrations for flow and had no issues following iy and adjusting the multiplier. However, I'm not grasping something fundamental about leveling the bed. Everything I try ends up with really poor results.
I prefer just starting a big print and use live adjust until it looks right, then just hit save
