Wiring the steppers

IMG_20151022_112457Using this wiring kit, you really just need to plug in the motors, tape or otherwise secure the connection and go.

There are now two wiring choices. I highly recommend  you start with the series wiring kit. The dual kit adds complexity with that complexity you gain accuracy and precision. More dual endstop information here.

The DIY way

The stepper for the z axis just needs its wires extended. Usually you would just cut the plug and splice in some 4/24 shielded cable and be done with it.

 

Series –

Same amp draw as a single stepper (heat), twice the power, slightly less top speed. We do not need to worry about top speed, delta’s maybe cnc’s, no.

Parallel

Twice the amp draw as series (heat) less power, slightly higher top speed.

The steppers for the X and Y axis are wired in parallel, with the far motor getting one coil wired in reverse.

So to reverse this stepper you would wire this blue to the other yellow, and this yellow to the other blue. Do not get caught up in my colors, the position on the plug tells you what 2 wires are pairs.

To wire in parallel you connect all the like colors and plug it into the ramps board, then on the far stepper change on pair/coil.
