Are you printing with PLA or ABS?
Print head temp for PLA is around 190.
Is it not coming out of the nozzle at all?
Perhaps is the extruder problem solved by the motor driver curciut swap and by tightening the extruder spring for grabbing the filament and pull it in in the extruder…. but I can not get it confirmed because of a new problem occurring!! 
The New problem is: the Y axis movement can only move forward, not backward. This can be experienced in the Repetier host software. Movement problem are experienced when manually pushing button in the Repetier printing panel and in the automated printing program in Repetier. However, the bed is easily moved in all directions by hand force, when the printing program is not running.
I will try to swap the motor driver curciut again (but I swap it with the driver for the X-axis)
Is there any other obvious thing to do?
Cheers!
Check if the Y-Endstop is working properly. When it’s not the case you can only move the axis away from the endstop.
Usual issues : bad contact, loose or broken wire, wires soldered on the wrong terminals of the switch.
The 2 wires going to the Y axis
Make sure they are not rubbing on the frame
I used a small cable tie and strapped them to the post holding the end stop
Sorry I used the wrong term (Hobbit)
I didn’t mean to take everyone down the wrong path.
Lol
Thanks, I try and report!
I manually gentle investigate the cables AND at the same time try to make the beds y-axis go backwards (-) minus direction. No difference in function.
(I will later on strap the both wires to the y-axis micro switch end stop as you suggested “Wrong Way”)
I have to say this again but now in detail,
I discovered high frequent noise, probably from the step motor. This noise occur when I push the “moving buttons” in the software panel. The noise appear both when the bed is moving as it should be and when the problem of NOT moving.
For each push on the button, I can hear a new noise. (the volume is very low but all of them with quite high frequency). In the case of the bed not moving one last noise last about 10 seconds after pushing the button. Then the noise stops and it seems to “release a tension” on the step motor. My GUESS is that currency/voltage is feed to the motor but something hold it or hold it back… can’t explain it in a better way… please ask me for clarity.
Is the above behavior normal? Can there be partial problem with the circuit board?
Greatful for feedback!

Does the motor stop making the noise after awhile?
I do know that the motors will make a little noise after they move for awhile.
Try pressing “Turn Motors Off” in the manual section when the noise is happening.
If the noise stops it means that the motor was just holding it’s position.
This is normal.
Yes, the noise from the motor stop sounding after approx. 10 seconds (when not initiate any motor movement). After this 10 seconds and noise disappear , I can move the beds/motor with normal hand force.
There can be a change in noise frequens when I initiate the motor to run in the opposite direction. The noise of the motor can stop sounding when I use another motor straight after.
It’s a little bit confusing and complex behavior and I am uncertain about every single behavour considering all the combinations of movement and stops for all motor and situations.

Hi dedicated followers on the forum (Wrong Way… 
Now, two interesting findings
-
I have swap motor drivers circuits - the y-axis motor can not move in the minus direction, still.
I now understand that dedicated indicator diode (LED) are lighting up on the curciut board when initiating specific movement in the software printer panel…. nice discover! -
I also observed that the specific LED light for y-axis direction was a lot less light-emittance than the other LED’s in the board when executing commands.
MY obvious conclusion is that there is less current to the y-axis step motor, that’s why it not moving. The “current loop” (circuit board and hardwire together) have bad soldering, component flaws…?
I do not how to move ahead in the investigation. I really don’t want to tear down all hardwire cables to fault search manually on every single “cable-thread” with my standard multimeter, just to find out that the problem is on the curcuit board… Any hints or suggestions???

Before my progress story - a quick question:
During print of my Circuit Board Cover:
My printed material got detached from the heated bed. This happened after about 2 mm printed material (2 mm in height).
Also, the 4 corner of the cover, when printed 2 mm in height, will lift up from the heated bed
-Maybe is there a non-optimal temperature level of the filament extruder or the heated bed??
Anyone?
Br/T
If you’re printing PLA, put blue painter tape on the bed and nothing will lift or detach.
I run my bed at 70 degrees for the first layer and 60 degrees thereafter. Parts are then hard to break loose until the bed has cooled below around 50 degrees. Adding a brim to the part will help too.
Thanks! I will try your valuable hints!
Yes, I use PLA for the moment
…… by the way, how do I change the bed temperature from one layer to another? the way you suggested it Paul!

If you’re using Cura you can’t but with Slic3r go to the Config/filament settings and there you can choose a different temperature for the 1st layer and the others.
thanks.
Also another issue, the melted filament will sometimes get loosen from the previous layer. Is it the same procedure, to increase the temperature level for the extruder?
[quote=“toban73”]the melted filament will sometimes get loosen from the previous layer.[/quote]Does it happen with PLA or ABS?
What are your temperatures?
I use PLA, and the preset temperature is 190 celcius degree.
Do you use a fan-duct to cool the piece?
