New to 3d printing. Looking for resources

I have no experience with 3d printing and just picked up a 2nd hand prusa mk3s+ looking for good resources to learn how to begin this journey. YouTuber recommendations? Blogs? Things you wish someone told you when you first started?

RE:

https://www.youtube.com/@ChrisRiley have alot of good educational content.

The handbook, https://help.prusa3d.com/tag/mk3s-2

DO NOT START ANY PRINTING BEFORE CALIBRATION!

The sensor or settings might be be askew .

First thing to get comfortable with, is heating up and loading and unloading filament.

Then under HW Setup, choose a sheet you have, then reset that profile.

Next, run a first layer calibration on the selected profile.

 

I would go with smooth sheet and pla filament. That is most forgiving combo.

Another good link for first layer calibration. https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/life-adjust-z-my-way/

When you get a feel for how it should behaive, then you can install your slicer and go theu the wizard adding your printer.

 

I would hold off updating the firmware if the printer runs fine as it can be a challenge if not all steps are done in order., you may get a firmware warning that you can push the turn-knob to acknowledge.

 

 

I only updated firmware on my 2nd print i picked up locally second hand while doing some maintenence and swapping nozzle, i still run my "first" mk3s+ on it's factory firmware without issue.

RE: New to 3d printing. Looking for resources

I got a new MK3S+ a number of years ago as my first printer and I didn't bother learning anything about it before starting right in.

It worked perfectly out of the box.

I printed more than a dozen spools before I had my first self-generated problem.

Then I started learning about the machine and the process.

I've done thousands of prints since then, all original, all my designs. I don't think of myself as an expert, but I can get what I need done, done.

I say "Wing it!"

Thank you. I was told that it did need a calibration when I got it. When I get home from work tonight I plan on trying it.

I was looking at getting something from bambu lab but I really disliked that everything was proprietary. So I was on the fence when I saw the mk3s+ up for sale at a local auction and decided to get it. Ended up paying less than I would have for the bambu labs mini. $240 after auction fees

Do you know of anywhere I can download pre spliced g codes?

First mostly successful print took a few trys to get my first layer calibration right and the first 2 times trying to print it i forgot to set a bed temp so it wasnt adhearing well. But on my final try it came out okay. It started to lift in the front shortly after starting but the rest stuck well. And theirs some weird wavyness to on the layers 1/3 of the way up from the bottom of the cabin will need to do some figuring out.

In My opinion, the first layer calibration tool wrapped in the Mk3 series printer firmware, is not the easiest tool to use. 

there are many first layer calibration tools available, lots of people have their own favourites.  one that is now quite old, helped me, immensely, when I Was new to printing, and is still useable today

'Life Adjust Z My way'
https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/life-adjust-z-my-way/

I find that I can adjust the Z setting as the print progresses and get good results. 

there are test print files (In a zip file) at the bottom of the first post. 

Prusa Printables 
https://www.printables.com/
offer a number of pre sliced gcodes. but there are issues... 
gcode formats differ depending upon which printer they were created for. so you need to be careful what you try to run, on your printer
More recently a new binary form of Gcode has arrived on the scene.   It's Binary Gcode .bgcode files...  as far as  I am aware, printers with 8bit processors (Such as the Mk3 Series printers cannot handle .bgcode files

so please be aware that pre formatted gcodes may not be suitable for your printer

regards Joan

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK

@proX gaming - Why do you want pre-sliced anything? Half the battle is slicing properly. Each printer, each filament, each setup is slightly different. Learning how to slice is easy. Learning how to slice properly takes a bit of time but the only way you'll learn is to try.

The Printables model repository has lots of stuff to practice with. I suggest finding a project that has real use and go about trying to make something that will be useful. That way, you'll really be able to judge your efforts based on real world outcomes.

Good printing!

So I'm getting ready to move soon and haven't wanted to do an actual computer setup for this and I was intimidated and struggling to find workaround using a cellphone. But I've got it working fairly well and starting to grasp the different setting. So rn I'm using tinkercad mobile app to view/edit .stl files then I upload them to cnc-apps.com which has a stl to gcode converter which gives you a bunch of different options. When I make the jump to the prusa slicer I don't think it will be too difficult. I learned Autocad a few years ago and that seems to be kinda in the same realm

I think you'll find Prusaslicer to be extremely simple. It really doesn't do much, just prepare the layers. The options determine the outcome and it really centers around the temperatures required for the filament. The slicer program is loaded with a lot of other stuff, mostly useless, but probably necessary for some who don't have a good cad program.

I suggest jumping in at your earliest convenience. You're jumping through a lot of hoops for nothing.
