Post Another DIY build- Thanks!....and need some clarification

First off Thank you! The quality of information and knowledge you are offering up to the community is impressive. I have been looking for a good project to get into for awhile but was a little intimidated with the electronic aspect, but with all the information you have supplied I went ahead and purchased the parts to build the Chronos timer from the ground up. Never touched a Arduino before, but wanted too.....anyway thanks!

Now my question. I am soldering the connections for the stepper motor controller (Pololu mb 09b) it shows 3 micro stepping pins ms1-ms3. The diagram only refers to pin "ms" can you clarify what the correct pin is? I assume ms1..
Also, the part list calls for 26gauge stranded wire....is that thick enough to power the motor? The wire coming from the motor is much thicker. Thanks again for all you have done thus far!

all togrver M1 to M3
the Programm use only normal Stepping and Microstepping ( High or Low on all M pins )

Yes dirk is correct, The current configuration uses all 3 MS pins are hard wired together. This means it has 2 step modes, full step and 16x microstep.

Im glad you are interested in the build! if you run into any problems do not hesitate to ask :)

Ok....got that part. Thanks! The only thing left to wire up is the input 3.5mm jack. and the "res" button. The diagram is a little confusing to me. Do you have any photos of how this works? Also the button labeled "Res" Is that part of the input jack wiring? Sorry if you already made this obvious, but I'm completely new to this.

are you going off the schematic? or are you following the instructions to build the controller?

Schematic.....I just found the instructions.....wow, this would have been a lot easier. I guess I read "Control box construction manual" and figured it was the instructions to build just the box. I guess I can review that to see how much I got right. Thanks!

Do you have anymore of those controller shields pre built? Mine is quite a bit different, and im not sure its worth the time to trace down every circuit on mine, considering the very real possibility it wont work anyway.

we only have a couple of those left, i actually spent a good part of today designing new boards which will use mostly surface mount components. I think you should continue with what you are doing, see if you cant get it to work :)

if you need im sure we can work something out, if you decide you really just want to use a new board let me know. my email is projectchronoshelp@gmail.com

Good news! I plugged it in and uploaded the sketches, and I have working LEDs! (after discovering a short under the LED pins) Seems to go through the mode dial and settings ok. Im trying to follow the instructions for calibrating, but I cant seem to get it into calibration mode....it does nothing when I press the "set" and "in" buttons. When I run the serial monitor I see no values when I press the buttons. Guess I'll be checking my wiring.

sounds like a short. you should see 0 as a baseline, when various buttons are pressed you should get different values back

sounds like you are making progress though :)
