First, I must appologize for, "Eating and running". Shortly after my first few posts, which resulted in many helpful replys, I dissappeared without due reciprocation. My wife was diagnosed with pancreatic cancer, and well, priorities were rearanged. Of a type where treatment has a high success rate, and no small amount of credit given to the prayers of many, the world over, improvment has been such that I have been able to return to the shop, and do so with peace of mind! So, thank you all. It feels good to be able to put my CNC hat back on! That said,....................................
There has been much said about, and no small amount of controversy, concerning using connectors to attach stepper motors to cables and controllers. This being in large part due to the SLA7078 driver chip. Allot of controllers utilize this chip, and allot of them have the same issue. The chip being ruined from disconnecting or connecting motor wiring with any voltage still present. The current stored in the electrolytic capacitors being sufficient to do this. Having to wait for this current to disipate goes a long ways towards defeating the advantages of using connectors, as well as a non-locking connector unintensionally seperating. There are SO many different connectors, and a LARGE number of locking connectors, AREN'T! After doing ALLOT of looking, and purchasing more, "Samples", (I remember when samples meant, "Free")-: then I care to total up, I've chosen what, at least for me, is the best, overall, solution. FINALLY coming to the end of THAT road, I realized I was only half way there, needing to solve the, "Blown driver chip problem".
THAT part of the equation now being complete, here's what I came up with. http://www.mikebeck.org
Again, thanks to evryone for their replys to my requests of, well, it's probably been at least, 2 months ago. It is my sincere hope and desire that nothing will befall me this time, to prevent my, "Sticking around", to participate in kind!
Thanks in advance for all of your input!
All the best of the best to the best!
