In preparation for the final build stages for my JGRO, I turned my attention back to the electronics..
If you've read my HobbyCNC build thread, you saw that I had hard-wired my steppers directly to the controller. This worked fine for testing, but "real world" means that I would need a way to separate the steppers from the controller from time to time.
I went down to our local Fry's (http://www.frys.com/) electronics store and purchased 16x 9 pin D-Sub shells and a pack of 10x 9 pin male and 9 pin female connectors. I cut the steppers free from their umbilical cord and wired up the connectors. I put male ends on the controller and female on the steppers. I also took a step further and wired up the splices for the 8 wire steppers to 6 wire controllers in the male 9 pin D-Subs in the controller. This allows me to use a standard 9 pin "Extension" cable between the steppers and the controller (although, I'm going to make my own).
With the steppers free, I can turn my attention back to mounting them on the machine and finalizing the assembly. I hope to be cutting chips by the end of the month if all goes well!
