You sure have jumped in at the deep end!

With some tender loving care, and a lot of reading up, you can certainly get your printer to print decent if not excellent.

As to your nozzle, there are a number of possibilities why it clogged. It could be poor filament, poor 'hygiene' (I mean that tiny particles have attached to the filament and get pulled in to the nozzle to collect and clog there), too high temperature/burning/carbonization (not likely with PLA at 215), or too much retraction. In the latter case your filament gets retracted so far that hot gooey filament reaches the cool part and gets jammed there. As to the latter, do not use more than 3.5 mm retraction or so. Less if you can get away with it.

If your nozzle has gone to 3D heaven, just but a couple new ones. They cost a few bucks and you will not be without one when this happens again.

You have a delta type printer, which is very, very sensitive to the sizing of the rods (the arms holding the hotend), the towers, the carriages (vertical going things) and the effector (the part that holds your hotend). A couple of 0.1 mm difference will make the effector not to run exactly parallel to the build plate. Instead of printing in a flat surface it will print in a bowl or dome shaped surface. In this case, you can not get a good first layer and either the center or the edges will not 'catch' on the build plate and your part will not print right. You want to have an error of max 0.1 mm or so over your entire buildpalte. The reason for this dependency is that the firmware needs to recalculate how far to set the carriages in order to get the nozzle at a specific x,y,z position and needs these size parameters to calculate it on the fly. The slicer only provides the x,y,z positions, the firmware has to do the printer-specific (hardware) part.

If the dimensions set in the firmware are off with respect to the actual dimensions (pretty likely with a cheap chinese and/or self-build) then you need to set them right.

While waiting for your new nozzles to arrive, read up on what you need to do (just a few starting points, google for more):

You will also need to get up to speed with compiling and uploading your own firmware with arduino or others (just google it, there a are tons of guides).

Once you have achieved a good calibration print, you are off to go with printing (and have done a really steep crash course along the way....).

Success (yes, you CAN do it) !
