First Layer thickness

[rookiebeotch]

I am building some large prints for an RC sub.

Using rostock max v2 un moddified.
ABS 1.75mm.
Using repetier host with cura engine.
Couldn't use mattercontrol because it has a bug on 32bit linux. Just got a fix yesterday from matter hackers. it was missing serial library for 32bit linux
So since i did all my calibrations on repetier i'm sticking with it.



The first nose print came out great for the most part.

What i didn't like was the first layer and i am not quite sure which settings will create what i want.

Since i will be making 6 sections that will get connected together (like a tube), i wanted the bottom face of the first layer to be as solid/flat as possible. See the Pics. It looks like it is making a loose grid pattern which ends up getting peeled a way a bit when i pull it off the bed.

everything else on the print looks great, no drooping what so ever.

What setting will give me a more fuller/solid first layer? not necessarily taller but more filled in?

I didn't use a raft as a support but maybe i should?

Take a look at the guides in my signature - I describe how to tune that first layer using a single layer object. Your first layer looks like significant under extrusion or filament starving. There are a number of contributors to that:

slicing parameters for nozzle diameter, filament diameter, flow tweaks, etc
mechanical problems like filament diameter, extruder calibration, nozzle is actually what you think it is, slipping extruder, etc.

From your photo, it looks like even the 2nd layer is too sparse. You have some sort of calibration or configuration issue and I recommend printing the single layer object until you get that nailed.

Well...as i started reviewing my printer settings i found that i had the nozzle diameter at 1.75mm. Woops.
So that would explain why the spacing inside the single layer were so large. I guess i got real lucky that the cone i printed just had the right geometry to not notice this sooner.

Off to re-calibrate it all.


Thanks for help, that 1 layer object is a good idea.


I blame with all on windows 10. I was getting serial errors in arduino IDE because of a possible shit driver. Which caused me to install linux mint on laptop, which caused matter-control to not work because of another serial driver bug....

So back to the drawing board to make sure its all right...still fun.
