Hoping someone here knows what I screwed up.
In mid homing of Z axis, I bumped the RAMPs/Mega board and Z just stopped. After that I couldn't get Pronterface or Arduino to connect to the board. When I plugged the USB cable in, no "happy sound" from my PC either, although the "on" light came on.
Next I took all the cables off and removed the RAMPS and tried to connect the Mega by itself; same thing. So, after a quick trip to MicroCenter, I have all re-assembled. Here's what works:
USB connects quickly
Arduino was able to upload firmware
Nozzle Heat
Nozzle temp sensor
Bed Heat
Bed temp sensor
Endstop switches
What doesn't work:
ANY motor
X - nope
Y - nope
Z - nope
Extruder - nope and nope
I would appreciate suggestions on what may be up and how to troubleshoot it.
Thanks!
