I am wondering if I am shutting down improperly, as I am having an odd problem with the firmware file changing from FIRMWARE.CUR to just FIRMWARE, after shutting down my system. I currently power down by turning off the power supply to the Smoothie board. I just finished the setup of my smoothieboard and a Herculien 3D printer. I was able to test the limit switches, move the extruder all around the bed of my printer, and test both the heater bed and the extruder heater, including an auto PID session. Then I power it all down to go attend to other work, and when I return, and power up, the system is acting weird, with no power going to any of the motors or heated components.Power is on, the smoothie gets power and I can get to the web interface. Both times, I went back and hooked up the USB cable, I found the firmware name was FIRMWARE instead FIRMWARE.CUR; If I load a new copy of firmware.bin, disconnect USB, and power down the printer, it will all come back up, running properly.
But then later, it returns back to the non-functional state?
Is there a more proper way to shut down the Smoothieboard? Has anyone experienced a similar problem?
