Stepper experiment 26 of Stamp Works 1.2

I received an Errata sheet along with the above Stamp Works 1.2.· The sheet refers to a change in driver IC (from ULN2003 to ULN2803) as well as a changed stepper with different lead colors.

1. My NX-1000 board still has the ULN2003.· My guess·is this will work fine if I wire it right.
2. The supplied stepper has 6 leads (2 x Brown, red, white, orange and blue).· These colors don't match either the supplied manual experiment 26 or the errata sheet.

Suggestions will be appreciated.

    Hello,

    I couldn't find one that has two brown wires, you'll need to most likely connect both brown wires together.··The ULN2803 and 2003 are the same except for the 2803 has an extra channel.·

    I found the documentation that you are looking for and I've attached it.

    Thanks Dave!

    That looks like exactly the information I need. I'll assume the code stays the same. If not, I'll bumble through.

    That's actually an outdated version of the stepper documentation.· Here's the latest:

    Jon,
    Your document shows the lead color/phase relationship for the early Howard Industries stepper as well as the later Mitsumi. Dave's document shows lead colors that are representative of the stepper that actually came with my Stamp Works.
    My first trial results in only vibrating the stepper so I'll have to dig a bit deeper to relate the Program to the variations of data that you and Dave have provided.
    Thanks to both of you for a very prompt response!

    Dave,
    Thanks for your support!
    I switched the phase leads around until I got it to work. When I get a chance, I'll post the lead color/terminal combination that worked for me in case someone else has a problem.
