Just recently purchased a RAMBo 1.4 board, and got everything connected. It seems that I could have a faulty board. The E0 stepper will not respond. I did some troubleshooting by switching the cables with the X1 stepper, and found that the cable and motor were fine.
Any suggestions? Any help would be greatly appreciated
I’ve seen a couple of Rambos come across the forum where one of the steppers did not work. I know in one case, the person fixed the board by renewing the solder to the stepper driver. If you purchased it from a US dealer, then you may want to return it, but if it came from an overseas dealer…
