Hi,
Mega2560 R3 used for controlling a 3D printer through a RAMPS board
I recently changed to a new RAMPS board (1.6 from 1.4) and stepper motor drivers (DRV8825 from A4988) and had to change a few settings to suit.
With the Mega2560 disconnected from everything except laptop via USB.
I compiled and uploaded successfully, no errors. The LED on the board doesn't blink, it is on solid and none of the settings have changed at all.
Please help !
without code and wiring connection, I think nobody can help you. please post the code and wiring diagram
Hi IoT_hobbyist,
Thanks for replying. Given that the code compiles fine, and nothing is connected to the Arduino. I thought that the solution/workaround/troubleshooting would not require either of them.
Also the code was working fine before, I only changed a few variables.
Should I post the whole code ?
Maybe... You should ask the people that supplied your code this question?

Have you saved the settings to the EEPROM at some time in the past? If so, you will need to reset to factory defaults and then save the default settings to EEPROM.
