Extruder and hot end do not work correctly on ramps 1.4
Hello all,
I am a newbie on 3d printing, and electronics.
My Monoprice Select Makers V 2 (Wanhao i3 clone) has fatal problem, where its extruder capacitor blew up. I decided then to changed the whole motherboard to ramps. I found 2-in-1 sainsmart ramps board. I since installed the board on, until I tried to adjust the extruder motor.
The following are the problem that I have:
1. The hot end does not heat up, and it kept throwing heater decoupled error on the control board. I disabled the test on the firmware, the error disappeared, but the hot end is still not heat up. Out of the curiosity, I moved the wiring for extruder on the board, from ext0 to ext1. Hold and behold the extruder start to heat up. Is this correct? Btw I clone the ext1 port for my 2nd z axis . Since I have 2 z motor. The z axis works perfect.
2. The extruder motor does not work. It wired to ext0 port. I tried to adjust best, but it still does not feed the filament in. I can see the controller showed the filament moved, but not physically.
I am running out of idea on what should I do her, please I need help. Thank you.

1. For the shifted layer, I was able to fix it by updating the arduino program to the latest version, I think 1.6. I believe there is something in arduino compiler that did not translate correctly when it uploaded to the machine.
2. I added more stabilizer on the base of the printing base, I.e. put some shim on the bottom of the table.
3. I reduce the printing speed to 75% manually. This help with the quality of the printing.
4. I made adjustment to the steps per mm for all the motor, based on some suggestion from YouTube channel. Very simple process, but it takes time to do so.
If I would like to reduce the speed and acceleration of the motors in the firmware, which line of code should I adjust?
Once again, I am grateful for the help.
Is this mean the machine jerking?
Afterward, I noticed the printing start to shift between layer.
I believe this is still a crosstalk problem, is it true?
Btw I try to understand the crosstalk.
How do you fix it?
Do I need to bundle a motor cable with the end stopper cable, I.e.: y motor with y end stop, etc.?
I read from some other group, it mentioned about wrapping the cable with aluminium foil.
Does it make any sense wrapping the cable with aluminium foil?
Thank you.
I am curious, How do other users getting over the problem on rumba?
I thought about connecting the z axis motor in series to a stepper drive, but I against it due to potential overheating on the driver.
I will e interesting to learn about the solution.
Thank you.
