Runout sensor does not work. The printer continue without filament. The green led of sensor works correct, when the filament is over goes off. Does anyone check the sensor ?

the printer begins very well but after 40%-50% of printing the part unstuck from the heated bed. I use 60 degrees in heated bed, Build Plate Adhesion - Brim. Any suggestions?

I connected octoprint with rasberry B (not plus) everything prefect. Did anyone put the ribbon cable from the left side? I am afraid that the length of the ribbon cable is not enough from that side.

can we connect cura with the printer through a lan ?

After an unsuccessful first printing i noticed that no filament comes out of the nozzle. In build guide stage 10 step 28 was successful. I repeat this step and after 30-40mm the extruder can't push the filament into the PTFE Tubing. In the fist 30-40mm the filament comes out of the nozzle and everything seems to be ok. I unload the filament, cut the end and load it again but with the same result. I try to push the filament with my hand and pressing the Idler Arm in the same time but once more the filament seems to stuck somewhare in the hotend. The temperature was 200, i try in 220 with the same result. The speed was low.

In the move menu the movement of X axis is in the opposite direction. Z and Y axis are in the same direction with the arrows.
