So I just spent the entire day troubleshooting this hands on and reading forums.
The problem: motors won’t move. Everything else seems fine.
I’m going to take a guess that it might have broken during its last catastrophic job. The table rocked so bad that it actually disconnected one or two of the motors from the RAMBo 1.4. Lessons learned from that failure, so let’s not dwell on it…
Anywho, would that mean that a disconnect with a driver active will kill that channel? No channels work, and there is no visible damage to the drivers.
I’ve tried every motor in every socket, and verified at least one motor pin-out from motor to connector to verify the continuity of the extension. I only tried moving the motors from the LCD screen. Also checked the fuse.
Any other way I’m missing to test the drivers? I don’t have another board handy to test the motors.
If my drivers are dead, is the board still salvageable?
