With luck someone can put me on the right path here.
I just ordered the Eding cpu5a4 controller to finish up the electronics on the CNC machine I have been tinkering with for the last year. Can I make a cunning DB25 cable to connect them directly, or am I better off using breakout boards to wire things up to the screw terminals? Electronics is not my strong suit, so I want to go down the correct path here.
So all you connected was the step and direction pins on each side? Did you run your estop or limit switches into the gecko side or the eding side?
No most everything to the G540. All you need to do is look at the pin out for Eding and pin in for G540 and pair up all you can. You can have a custom cable made for something like $35. Or just buy two DB25 cups, 2 covers and get some old ribbon cable and roll your own.
I have a build thread where I bought the custom cable, will find it tomorrow
The first attempt to get the electronics working was a bust, but I thought I would document it. Once I figure out the correct mapping, I will order a custom cable like louieatienza recommended. My first tour of the Eding software interface was good though, a bit easier to grasp than Mach3 for someone with no background in this.
I`m in the process of converting my old CNC from Mach3/Gecko G540 to Eding CPU5A4E or CPU5B and I want to keep my G540 board. I haven't make my mind yet and the facility to connect the board to the G540 may have an impact on my choice.
were you successful in making the connections to your G540 following advices from Louieatienza?
you say that you have the cpu5B; have you done the connection to your G540 and if so, what was the route you took? Did you buy the CPU5B Connection Kit from Eding or you did it a different way?
you mention you had a custom made cable for the cpu5a4 and that you had a build thread where you bought the custom cable; can you share the source for the cable?
