SOLIDOODLE PRESS SETTING PLEASE I'M LOST

Hi, I'm new to the forum, and I'll need help.

I just got my 3D printer solidoodle Press since Monday, and I try to print deuis this daate anything but impossible.

the problem my list is as follows:

with solidprints when I load a 3D model sometimes appears and sometimes not
when the beginning of the process to work the printer starts to print correctly and after you drop some lines it stops.

I have to turn it off and turn it on, for what works again.

Another problem when I load a former model and always there,
impossible to erase, even if I unplug the machine.

I am a student in industrial design and I do not know much in programing but think it is a software problem.

on some forum using cura, so I did the same, and most of my problem of chargerment are resolved.

I just have a problem when printing begins, the head and too far from the board and I do not configure this in CURA

If anyone can help me it'll be super cool
because I am French and my English is a bit light

I did not find the exact configuration on the forum Cura

thank you

by the way i think solidprint need a big update!
