sounds okQuote
1. motor for extruder is turning the right way, X-axis is going right when I press +X, Y-axis is going towards me when I press +Y (not sure if that is ok), Z-axis goes up when I press +Z.
I'd suggest you move your X-endstop to the left and connect it as minQuote
2. I plugged the endstops on ramps to be X max, Y max and Z min and when I press them and tipe the M119 command I get the confirmation that they are working properly
That's because it does not know what it's 0,0,0 position is w/o homing, so it assumes starting position as home, therefore it'll only go +Quote
Problem 1. when I connect the machine and give the command to move (for example) to the right it moves, but if the first command is to move left, avay from me or up it doesn't move. Only when I move them (for example) + 10 right, then i can move it back to that point where I started. So I am not sure if that is normal or not.
Makes sense - connect X and Y as min, move X endstop to the left and you'll be fine. When you hit "home" on particular axis - it should start moving towards your min-endstop, so just put endstop on that side and connect it as min. Max endstops are probably not as critical, since you can define your max/size in firmware.Quote
2. I don't know how to configure the home position. I tried several times. Sometimes the extruder would hit the endstop but not registered it and only trying to destroy the endstop. After some configuration it now moves away from the endstops when I am trying to home it, no mather what is the position. I don't whant to destroy my work so far...
My endstops are: X-on the right side, Y-behind, Z- bottom

The code that lowers the hot end when it starts to print is generated when you slice the object. You shouldn't need to add anything it should do it on its own. The machine will home, nozzle up then start the print at the point that is designated in the slice, usually around the center of the build platform. Since you seem to be getting familiar with G code save the code to disk and have a look at the file. It will open with a text editor. If it's not heading to the middle of the build platform to start printing it's missing something. Check to make sure the platform dimensions and center of the platform are correctly defined. IIRC in Slic3r it's in the printer settings options, right hand tab if you are using expert mode.
Cehck out the G code after the home to see if it's giving you movement to head to the print area, touch down and print.
