1- takes very long time to start and then when trying any feature it gives black screen and needs to be restarted.
Or
2- takes very long time to start then it shows a black screen and can’t show the normal display
I’m not profissional in repetier so i dont know what x server you are talking about plz give me a hint so i can look for it.
First, the pi 3 has wlan on board so adding a wifi stick is not required.
The other problem is that the pi is very power sensitive. It should be powered with a good 5.1V power source. Linux disables e.g. usb devices if power goes below a treshhold. Bad for printing as this disconnects printer. If even the display goes black your power may be very worse.Didn't have this problem so far, but all devices you connect take power from the pi power. So you have now these sources taking power:
- Pi it self
- Display
- Webcam
- Wifi
- Printer if it connects without main power.
That can easily be too much. That would also be the reason it works without some of them and not with them or unstable.
Webcam
Display
Printer
I think that this is reasonable items so what is the problem????????

if should work. But that was without a display also using a good portion of power. So try with webcam and without display if it then works. If it does you know you need more power to the pi to work properly.
Also it is often not good to send full hd webcam stream on a pi. Full hd is big and bandwidth is not that good over wifi. 640x480 is a good compromise and normally works well. This is around 25kb/picture.
