Thanks guys. I am subscribed to artengine list. The Ottawa robotics list sounds interesting. I will check it out when i get more time. <br><hr id="stopSpelling">From: darcy@siteware.com<br>Date: Sat, 28 May 2011 23:01:59 -0400<br>Subject: Re: [Lab] [ORE_bits] Nema 17 controller wiring diagrams<br>To: mikeysorensen@hotmail.com<br>CC: themumbys@gmail.com; ore_bits@yahoogroups.com; lab@artengine.ca<br><br>For the Artengine list post to <a href="mailto:lab@artengine.ca">lab@artengine.ca</a><div><br></div><div>In both cases you need to be subscribed.<br><div><br>

Hi, can someone tell me how to post a new msg/topic to the mailing list. I attended a 1 or 2 meetings along time ago when things were first getting rolling. Since then, I haven't been able to make it out cause of work. I still follow the mailing list sometimes but never really posted anything. What's the proper procedure and to reply to a msg, do i just hit reply all. <br>
<br>Thanks<br><br>- Mike<br><br><hr>Date: Sat, 28 May 2011 20:03:34 -0400<br>From: <a href="mailto:themumbys@gmail.com">themumbys@gmail.com</a><br>To: <a href="mailto:ORE_bits@yahoogroups.com">ORE_bits@yahoogroups.com</a><br>

Or A1,A2 and B1,B2 for example. Either way any 2 wires with continuity form a phase, each phase is either A or B, the order is unimportant. The polarity of the phase is, but you should be able to find that by trial and error (no risk of damage to the motor). Then the direction of the motor is swapped easily by flipping the entire wire order once you've identified the 4 wires...</div>

I have this Nema 17 controller and I’m just wiring it up now. It has some confusing documentation.<br>
The wires are Red,Green,Black and Blue.<br>
The motor diagram is labeled A,B,C and D.<br>
The controller diagram is labeled A- A+ B- B+.<br>
Anybody know what the standards are for labeling?<br><div>
