3D printing advice appreciated :)

Post by dashtag » Sat Aug 12, 2017 7:28 am

Hi, I'm a newbie 3D printer, and have finally managed to print the faceplate. It's useable, but I'm hoping to improve it. See photo below:-

This was printed on my Original Prusa i3 Mk2, Slicr Prusa Edition using default settings of I think first layer 0.3mm then 0.34mm and first layer 200%.
I tried using the advice settings of 0.22, 0.24 & 125%, but the first just ends up detaching & ending up in tangled mess of filament.
Thanks for any help received.

I can't offer much advice. I have a different printer so my settings are different. But yeah, took about 4-5 prints before I got one that I was happy with. Trial and error.

your prints look a million times better then mine, wermys prints look amazing i am yet to get any good prints from my tevo tarantula :-(

from the vids i have been watching though to try and improve my prints it doesnt look like the filament is hot enough? someone with more experience may say other though?

On what kind of surface are you printing? I did a few tests printing the faceplate on a piece of glass and that makes it a lot smoother.

With this calculator you can calculate the optimal layer heights for your printer: http://www.prusaprinters.org/calculator/#optimallayer
After I checked this I found out 0.22 isn't one of them :)

Just the heated bed that came with the printer kit (PEI material? I think).
If I place a thin sheet of glass on the bed, will the heat conduct through enough?

Cheers, I have a look at the calculator :)

In that case this video might be relevant for you: https://www.youtube.com/watch?v=jEgEQrQWupg
I've increased the temperature of the bed to 60 degrees Celsius on my printer after using the glass bed.

.3 might be a little too thick for the details on this print. Have you tried live z adjustment on the Prusa to get that first layer to stick at .2?

I haven't yet, I'll have to give it a try. I haven't experimented with live Z adjustment on any prints yet.

I'm just also confused why it didn't even print some of the logo & the corners around the screw holes.

It may be skipping it because of the thickness needed vs your settings (just a guess). I upgraded to the Prusa just recently and loving it. ;)

Check out this post to calibrate that live z just right.

Yeh, that does make sense.
I'm loving it too. But I'm realising that after printing the supplied sample Gcode perfectly, that it's quite a dark art when you try to print other models and have to work out the settings yourself! Lol

Cheers, I'll have a look at that 👍🏻
