3D printing advice appreciated :)

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.

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 👍🏻
