Which Board Do I Have?

[engi1]

I finally completely my Delta Rostock Mini assembly and I need some help because the controls behave erratically (wrong step length, etc.). So first of all, there was no explanation on how to set the jumpers, even though lose jumpers were included in the kit. According to the attached picture, which board do I have, and what is the jumpers configuration?

Accroding to your picture, the mainboard type is Sanguinololu. And the jumpers have been well plugged.
I notice that you did not connect the extruder fan. It is very important.

Thank you, but please let me know if my jumpers configuration is correct. Right now I had to guess, so I have populated all jumpers, but the printer behaves erratically. Please see the attached picture and let me know exactly where to put the jumpers and were not.

Sorry, my bad.
12 jumper caps should be plugged.

thanks, in such case I already had it correct. It still will not work. Only the X axis works fine. The other behave erratically. Please see my video and let me know: https://youtu.be/8YR6HrsetLI

When you move any axis, 3 motors will work together to keep the nozzle at the same level.
It seems that when you try to move x axis, only one motor work. I think the firmware is wrong.
Please check your email, I will send you a correct one.
