Does anyone know if the wire colors mean the same thing for the motors from SeeMeCNC and from MakerFarm?

I got one of these motors (see link) last year or early this year and I notice the colors of the wires are in different orders on the connectors. I need to snip the wires and wire up a connector that is appropriate for the Rambo controller board. I also have to set the current levels correctly for the new motor. This motor will be working as a secondary extruder on my Rostock Max.

Not all motors use the same colors of course so as long as you connect the coils correctly then your good to go.

Colors will vary from one manufacturer (of possibly even product line) to another, but the ones that come with 4-pin connectors should all have the two wires in for each coil adjacent to one another.

To check for the coils, Take 2 wires and connect them together. Spin the motor shaft. If you feel drag and the tic tic of the magnets the you have a set of wires of a coil. If not continue until this is felt.

I tested it on the Rambo and it seemed to work, but it was getting hot after just a trivial amount of work and it was making a ticking noise as it moved. I think the current is too high.

Thank you @Wayne_Friedt aand @Whosa_whatsis for the feedback.

I guess my next bit of work is properly calibrating the e-steps and current. Of course, if someone has current setting for that MakerFarm motor, that would help quite a bit.

#define MOTOR_CURRENT {195,195,195,195,195} // Values 0-255 (RAMBO 135 = ~0.75A, 185 = ~1A)

The last slot is the 2nd extruder. Since it is a bit warm, perhaps it should be set to 135-185 instead of 195.

From the MakerFarm site now (as opposed to September when I bought it):
5mm Shaft
Holding Torque : 66.61 oz-in
Assembled with a 4way Molex connector and 890mm (35") cables
20mm long D Shaft style so your Gears won’t slip
1.8 Steps
48mm Long

Sadly, it does not recommend the electrical specs.

The motor picture from the current website says cw no:130516 type 42BHH48-050-24A

http://forums.reprap.org/read.php?4,239074,239888 seems relevent, so I will read it and see what I can find.

I plan on trying some M908 P4 S (with S replaced with a number corresponding to an amperage) commands and extruding and seeing how that turns out.

Well, since I can set M908 P4 1 and still have it work, that command must not work for my firmware (Repetier Max).
