First layer issue
This is the most squished I can get my first layer to go and I literally can't go lower without destroying my nozzle. This is 2 layers thick 1mm nozzle 1.2mm first layer width.

Does the second layer looks good to you? I really can't tell from the pic

theres one small patch i dont like but honestly ive spent this much time with my first layer
im actually shocked at how much squish you all have
like with all my other printers the first layer was easy
this is the first time ive used a 1mm nozzle and wow is it different from the .6mm i have
genetic-orange•14mo ago
What's the layer height?
The too much squish is sus IMO...if your layer height is the same as the 0.6 nozzle it should have the same squish

but my .6mm nozzle is

SUS
Also I really dislike to do a different layer height for the first layer, hard to tune, and if there is a different it should be really small not 30%
inland-turquoise•14mo ago
what are your's set at?
like should i be setting both values to what i want my base layer height to be?
genetic-orange•14mo ago
Always the same
inland-turquoise•14mo ago
huh
ok
genetic-orange•14mo ago
And if you have a different color it would help 😛
inland-turquoise•14mo ago
that's how the SS profile for the printers started and I just followed it, i didn't know not to.
currently only black PETG unfortunately
genetic-orange•14mo ago
Also there is a slight chance that SS is trolling you with the space settings
In width & flow, see that the spacing between the lines make sense

genetic-orange•14mo ago
It should be slightly lower then your layer width...depended on how much overlap you want
inland-turquoise•14mo ago
120% like normal
genetic-orange•14mo ago
no, the spacing
to the right

ok looks good
inland-turquoise•14mo ago
i just ran the same print again but reset my EM back to 1\
never its worse now lol
ill set it back to .89 like before
with big nozzles "cutting corners" can help fill the gaps at the ends.
try it at 100%
inland-turquoise•14mo ago
ok ill run it ty

It doesn't look that bad to me....if it helps on my 0,4mm nozzle in the Minion and on Cura I have it set to 0,38 line width, it's how it showed the best results to me.
inland-turquoise•14mo ago
@elcoj my cutting corners was set to 0% orignally, im runnning the 100% now to see i just finsihed runnning the EM test againg and still got the same value as before, im printing the same test as before with the cutting corners turned on.
the setting only helps with the small gaps where the infill touches the walls, not with the gaps between lines. For that you just need to adjust flow
you should adjust flow based on the top of a calibration cube or something, at least 10mm high and not solid
otherwise you cannot distinguish z-offset from flow
inland-turquoise•14mo ago
the standard calibration cube or the actual flow test in SS?
cuz the cutting corners did make the edges alot nicer for sure
I think this is a good quick test: https://www.thingiverse.com/thing:1622868
Fast edge over/under extrusion test by NirDobovizki
I doing some testing and I needed an over/under extrusion test I can repeat with different settings without wasting hours or tons of material - so I designed this little thing.
It uses about one gram of filament and takes 7 minutes to print - and you can know if you have over or under extrusion without any tools.
Print with 0% infill and 1.2mm s...
inland-turquoise•14mo ago
but your 100% right not the lines
don't bother with the calculations, just print 2 at a time until they slide into each other perfectly
but after that, just look at the top of a cube
you might want to scale up this model for your large nozzle
because it needs to be printed with 0 infill and 3 walls
and is designed for 0.4
inland-turquoise•14mo ago
ok ill print it at 200% scale to get 3 wall
ty
@elcoj ok so
outside 19.61
inside 20.22
but his test is and calculator tells me to change my EM, but you said adjust my first layer flow
Don't measure, print 2 at a time and slide them into each other
First get your flow right, then z offset
Don't use a different flow for the first layer
Well, maybe for a textured sheet it makes some sense, but z offset it's your main adjustment
inland-turquoise•14mo ago
will do
sorry for the million questions. the part i was confused by is you said to increase my flow but the test for EM, if the parts have a gap when i print two at the same time and slide them together, how do i know how much to increase my flow by?
The calculations didn't work well for me. So just increase in steps, it's a super quick print
It's important to have 3 walls without infill
If this fits together perfectly, other prints will to
genetic-orange•14mo ago
@mr.robot7392 Did you solve it?
inland-turquoise•14mo ago
still running EM tests, i honestly cant get it any better, the part that confuses me the most is if i run a print the way it is now with the amount of first layer squish that i have the prints turn our great, i have no complaints.
