Topic: Filawinder - Fried my Nano?
Currently, my filawinder is not working at all. All that happens when you turn the power on (auto or manual) is the servo jerks to the left, then nothing. Pushing buttons or knob does nothing. I've tried to get the troubleshooting window open, but have nothing working there either. I've got the jumper on the 2 D11 pins, the usb connected to PC, and Arduino IDE open with serial monitor on 9600 like in the image. Nothing shows in the window. I try all the buttons and knob and different settings in the IDE, and nothing.
I've tried to reupload the 9a sketch, only to fail. I only get this generic error that basically says the nano is not connected properly (stk500_getsync(): not in sync: resp=0x00). The PX light blinks 3 times quickly when I click upload (Send: 0 [30] [20] ), then nothing. I've tried all the driver and program reinstalls as suggested by the search on that, but no dice. It just doesnt seem to be connecting. It does nothing when the reset is pushed on the nano, and I've read that means the bootloader wasnt installed. I tried to rewrite the bootloader with the same not connected issue. On another computer, I cant get the sketch to compile, (Breaking at the QTR sensor part), which is another irriating issue. Thats the machine I use for my RAMPS firmware, so I dont know why it doesnt work there.
I feel like I fried my nano, but dont know how to confirm.
I had my winder up and running when I got it a few weeks ago. Auto and manual mode worked correctly, but one of the red buttons didn't work out of the box. I went to radio shack to pick up a replacement button. This started happening right after I connected it, then set the limits for the servo. When I pushed that button to set the right limit, it was all still working and spooling, but when I turned it off then back on again to see if it remembered the spool settings I had just set, that's when it started acting like the nano is fried. The button matched the 3A 125v AC markings of the original button, but it seemed like it sent a shock through the system. Could have just been a coincidence.
Anybody know of a basic way to test the nano and confirm its still working? Am I missing something about the upload to nano, like a pin jumper to get to bootloader mode or something? I get tired of reading through the arduino forums. I'm a front end web developer, and designed and built my own delta printer (built 3 total), but this C style coding and microcontroller issues make my brain bleed.
