new at 3d printing

my nema17 has 6 wires 4 blue 2 brown how do i wire it up to my ramps 1.4? help please on this subject Rego
ps im new at this 3d stuff i am building a reprap printer bought most of it seperately

The blue wires have to match to A,B,C,D on the picture. (6 wire stepper - top / right). The brown ones have to be those in the middle. Do not use them.



You have just to find the couples. Each couple have to has a small resistance between the 2 wires. After that connect each couple one after another (A,B - C,D). You have to check the direction of movement, and if it is wrong, switch the couples ( C,D - A,B ).


ATTENTION: Do this with disconnected Power and USB cables!!!

thankyou so much i forgot to mention the wires are blue brown blue blue brown blue on my 6 wire stepper so still the 2 browns no connection?
or is it a different pinout ps thanks again

Hi,

Usually Blue-Brown-Blue is one group, that means the Blue wires from this group is the one pair. Respectively the other Blue-Brown-Blue is the second group.

You HAVE TO MEASURE the resistance anyway...

For example: If the resistance is:
Blue-Brown = 4 Ohm; Brown-Blue = 4 Ohm and Blue-Blue = 8 Ohm, then the this couple Blue-Blue is your first couple ( A,B ).
The same have to be on the other Blue-Brown-Blue group, and its Blue-Blue couple have to be the second couple ( C,D ).

I hope you understand me... my English is not good enough.

thankyou DBS got you now are they good enough to run these 3d printers?

They looks very good... Big enough for almost all types of 3D printers.





BUT, I can't find an info about dergrees per step. If they are 1.8° or 0.9° , all is ok, If not - they are NOT suitable!

You have to check this!

Best Regards

These motors are 1.8º step

thanks so much dbs and siil yous have been a great ....regards Rego!!!

Can you please tell me the best software programs to use on reprap or other 3d printers
Thankyou would be much appreciated regards Rego
