First of all take a breather and slow down on hitting the submit button You posted the same question 4 times.
So Please go back and delete the redundancy.
1) i do not know if solidoodle ever published an illustrated parts bulletin. And do not know if you know this but they went bankrupt IIRC 2 years ago. Most parts are available as the machine is open source. and some need to be 3 d printed. Check for solidoodle on thingiverse.
Most here use repitier host that has cura and sli3r built in.
there are other software options.
There are many you tube videos that should help you.
Hope this helps
you need a model
then it needs to be sliced (CAM) then run the g code.
before that make sure the machine is set up and tuned.
