Beggining with my lumen, couple of issues

[dontHaveTheCow]

1. When assembling my lumen v4.0.1., Y striker cannot be secured with M5x25mm socket head bolt as noted in documentation. I used M5x16mm found in parts kit;
2. Then, when Y striker is secured, it is too low for the y stop switch. Upon first homing, i got y axis to try to move beyond physical capabilities and crashed into frame, cause y switch didn't get triggered; Y striker needs to be lifted ~3mm to be aligned with a stop switch;
3. I am not able to get any image when using top camera with 1920x1080 5FPS YUKV. Sometimes its gibberish, sometimes its blank. But i get good image when using 1920x1080 30FPS MJPG. I got not option to set 1920x1080 10FPS.

Point 3. was resolved by plugging USBs into different ports/hubs.
