Pronterface won't connect anymore
February 04, 2015 10:06AM
Hi guys,

I'm having trouble connecting my Prusa i3 to Pronterface.

I have been printing for 6-7months succesfully. Last week I wanted to replace a fan and I got some sparks and ashort circuit I believe.

Now when I try to connect to Pronterface it only says: ''connecting...''


I have attached a photo of my Arduino.

Hopefully someone has some tips, any help would be greatly appreciated.

Cheers,

Imhotep

Is the Arduino recognized by your computer when you plug in the USB cable? If not, then try another USB device (thumb drive, cell phone, etc.) to see if they are recognized. If they are recognized, but not the Arduino, then the Arduino is bad. If other devices are also not recognized, then I suspect the port on the computer may be damaged.

If the Arduino is recognized by the computer when plugging it in, check to be sure the computer didn't bump it to a different COM port address. You can test this by connecting to the Arduino with the Arduino IDE.

Hi David,

Thanks for your reply.

My arduino is connecting with my mac. When I try to upload a new program it says: ''timeout communicating with programmer''

The on led lights up and there is a yellow light burning at ''Aref''

The LEDs and connection to your Mac is great news! It is possible (likely) that the port assignment for the connected USB has changed, and needs to be updated in the Arduino IDE and Pronterface.. I'm not very familiar with iOS, so I'm afraid I can't guide you how to check the port address. sad smiley

Actually, I'm not so sure that you have a viable connection between the Arduino and the Mac. Yes the LED's are a good sign, but the message "timeout communicating with programmer" is not. It looks like the arduino is powering up, but there is no way to communicate with it. If you cannot even upload one of the arduino IDE sample programs, then my diagnosis would be that the arduino is beyond repair. I guess it could be just that you are using the wrong port, but like mindrealm, I am totally unfamiliar with the mac operating system,

Hi guys,

Thanks for your replies. I checked the ports like 5 times so it should be good by now...

I decided to buy a new Arduino mega, all these hours spend trying to fix it are just nog worth it.

cheers

Hi guys,

I'm having the same problem here. I used to run my printer on another computer. I'm using teacup and pronterface, with an Uno. I have no trouble uploading the firmware, but I'm not able to connect the printer to pronterface. The usb port is ok, the baudrate is ok... Anybody have an idea ?
Cheers

Windows? Which port is it? COM10 or above?

... when installing my Pronterface-based software on a new computer I have first to install the Arduino IDE with it's own drivers, or the Arduinos will be installed as "standard" USB devices, which aren't present in Pronterface ...

I tried that, installing the driver from arduino ide, (I also change the windows8 setting to allow installation of unkown driver) but still no connection.
I wonder if I'm not missing something very obvious here. But I went through the installation of the different software several time, and still have no clue of what's going wrong.

Thank for the answer anyway.

You should be able to connect via ArduinoIDE. Select the correct port and open the serial monitor. Maybe you need to change the baudrate to 115200 in your firmware, afaik the ArduinoIDE don't support 250000.

I don't understand what I should do after I opened the serial monitor ? What do you mind by connect via ArduinoIDE?
Thank you for the help.

... if you start the ArduinoIDE, set the correct board and baudrate, you can see the serial feedback/handshake of the firmware in the serial monitor window.

With wrong baudrate you'll see some cryptic chars when starting the board ...

Hi Viktor,

ok so when I open the serial monitor, nothing happen. I tried this tutorial : [www.instructables.com]
- I loaded the sketch, set the right baudrate, and was able to send and receive data.
So I guess there is a problem in the baudrate set in my firmware right ? But I checked that and it seems alright to me. I didn't go through all that trouble with my previous computer (the only difference was that it was running on windows 7).

Press and release the Reset button. This should send the word "start" over the serial line. If there's just some garbage or simply nothing, try other baud rates. One can simply try all of them: 19200, 38400, 57600, 115200, 250000.

Sorry to appear ignorant but does this mean the reset button on the actual Arduino hardware?
