A huge Package from a viewer 

Very cool. 3 D printing is very handy. I bought a Prusa as my third printer and now I can print rather than tune printers. Hopefully the Ender will work well. Step 0: Don't breath the fumes. Dry filament is step 1. Unless you live where the humidity is very low, you need to keep it in a sealed bag with desiccant packs. I bought tiny digital humidity monitor pucks to put in each bag. A cheap food dehydrator works well to dry the filament. Seeing a roll of filament out of the bag means it is not ready for printing. With moisture PLA becomes brittle and the moisture in it turns to steam when printing and screws up the flow rate and causes stringing. 2. Always start the print the same way. I wipe the bed with a paper towel and alcohol before every print. Oil from fingers will mess things up. If he print doesn't stick well to the bed, raise the first layer temperature and bed temperature. If it sticks too well, lower the first layer temperature and bed temp. 3. Print the first layer. Stop the print. Peel it up. Measure the thickness with calipers. Make adjustments until it is the correct thickness. These steps will ensure a good print. I often go with a thick first layer to avoid problems. Maybe 0.28 mm, then drop to the desired layer thickness, maybe 0.2 mm. A thick first layer helps deal with small variations.

Filament goes in the back-right, under the red thing, and feeds through the red thing (which is attached to the extruder motor), through a tube and into the extruder, which is where it's melted and dropped onto the part you're making. You can squeeze the handles of the red thing to disengage the extruder gears and allow you to push it all the way through if you like. Cutting the filament at about 45 degrees might help feeding it through.

Congratulations and welcome to the world of 3D printing!

Finally ) Long live to the viewer!

I have the same printer, once set-up well, it's a great printer IMO.

It's very hard to print flexible filament with a bowden exdruder like one ur printer have but u can conver it to a direct extruder. Websites like thingivers are full of ready-made models to convert your printer into a direct extruder.

I was following some nice tinkering channels in the past, then they got a 3d printer and from then on, they got lost in the subject and all videos after that wre about 3d printing stuff. I truly hope you wont go down that route, i dont want to loose you that way, like i did many others.

get a probe and convert to direct drive , or do the conversion mod !
