Pronterface Failure to connect

[Gary Schwartz]

My PC is unable to connect to RAMPS/Arduino on my MG Prusa.

 

It says "Connecting ..."      Build area of screen flickers, but no connection occurs.

Connection is via USB (COM2) that has worked in the past.

WIN7 Home Premium, 32 bit.

I get "blonk-blonk" sound when physically connecting USB cable.

RAMPS green LED blinks when physical connection made.  Several red LEDs on Arduino come on & stay on.

 

Only clue I have is the following log from Pronterface (Printrun?). 

 

"Pronterface (printrun?) log has the following entry ... for each time I try to connect.

Traceback (most recent call last):
File "pronterface.py", line 1566, in connect
File "printcore.pyc", line 76, in connect
File "serial\serialwin32.pyc", line 30, in __init__
File "serial\serialutil.pyc", line 260, in __init__
File "serial\serialwin32.pyc", line 56, in open
serial.serialutil.SerialException: could not open port COM2: [Error 2] The system cannot find the file specified."

 

COM2 properties recognizes the Arduino, and says it's operating properly.

 

My conclusion is that I need to re-install something somewhere.  My lack of knowledge prevents me from identifying, finding, and installing the "something".

 

Can anyone help?

[Dean Piper]

Unhook everything and close Pronterface. Shut down PC, plug in USB, start PC, start Pronterface. I get this some times, the serial port gets locked by an executable. You may be able to find a hung process that is using it if you look in task manager. The USB/Serial needs to be hooked up a few seconds before you start Pronterface at the minimum.

Thanks Dean.  It didn't work for me. 

 

Something evil is going on in my PC.  Here's the latest log of three different attempts to connect.  It's saying [Error 1], then [Error 5], then [Error 2].

 

I installed Komodo in order to take a look at the errors noted in the files.  In  serial\serialwin32.pyc", line 56  it said "port must be configured before it can be used" 

 

I seriously need help; I have a lifeless printer.  My only thought is to uninstall then re-install all software that could contribute to the failure to connect.

 

Can someone tell me what that software is?

Gary, the first thing that I would try is to uninstall pronterface.  It's a bit tricky, though, as pronterface doesn't "install", it just runs from your unzipped directory.  So first delete the exported files for pronterface.  Then delete the file "printrunconf.ini" in your home directory - on Windows 7 that's C:/Users/Gary assuming your username is Gary.

Then unzip pronterface from the zip file again, and test it.

[Gary Schwartz]

​Thanks for the comeback, Joshua.

 

" delete the exported files for pronterface"  What & where are these?

The folder that pronterface is running from; Downloads/printrun-win-Mar2012-slic3r is probable.

[Gary Schwartz]

​Joshua​

I deleted all instances of slic3r, printrun, pronterface that "Search Everything" could find on my system.

 

Then I did all three of the following:

​*

delete the exported files for pronterface

​* ​

Then delete the file "printrunconf.ini"

​* ​

Then unzip pronterface from the zip file again, and test it.

​"

 

 

Still getting "connecting ..." but not doing so.  Latest log says:

I allowed "connecting ..." to run for a few minutes, which resulted in the following log:

Error: Attempting to use a port that is not open

 

I tried disabling, then re-enabling COM2. No luck.

FWIW Simplify 3D Creator won't connect either.

​​​

I will now look for malware on my system.

Do you, or anyone have another suggestion?

[Joshua Wills]

When you connect the USB cable to the Mega, do any LEDs on the Mega light up or flash?

Also, and this sounds stupid, but have you tried another USB port, or another computer?

[Gary Schwartz]

I get a double flash of green LED on RAMPS, and several red LEDS on steady on the MEGA.

I have four unused USB ports ​& tried them all with same result.  Fifth port is for wireless mouse ... haven't tried that one for pronterface.

 

Different USB cable ... no effect.

 

Haven't tried another computer.  What software should I install?

Depending on how you launch the app, you should be able to right-click on its icon and Run as Administrator.  But if you're logged in as admin, you should be good.

I'm attempting to try it on my main computer (Win7 Home Premium 64 bit)

The Arduino Mega ​2560 appears in Device Manager "Other Devices" with a question mark, and says drivers not installed.

 

That's not surprising in view of what Arduino site says:

 

The Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the ATmega16U2 (ATmega8U2 in the revision 1 and revision 2 boards) programmed as a USB-to-serial converter.

 

I'm in need of more help.  Maybe a recommendation for a different hobby.

Don't give up.  Your "different hobby"  will need stuff your current "hobby" can provide.  

[Gary Schwartz]

Replying ​to my own post ... looks like I've really gone around the bend.

 

A bit more digging and I conclude that failure of the ATmega8U2 must be on my list of potential causes.  I could probably verify or eliminate this if I could get my main computer to recognize the Arduino as being on a USB serial port.  I'll see what turns up Google of ATmega8U2 on Win7.

[Gary Schwartz]

 

Even if it's sculpturing?

[Gary Schwartz]

 

 

This looks like what I need, but I don't know where to put it.  Please resist posting your first thought ... all others wil be  valued.

Would someone with Arduino Mega look on their PC for a file like this:

 

mdmcpq.inf

 

And let me know where it's located.

[Gary Schwartz]

Joshua/Rick,

 

This .inf  file appears to be a must-have in order for Arduino to connect to PC via USB.  Certainly someone at MG knows where it resides.​

Can't you just right-click on it and specify a new driver and use the one found in the Arduino IDE download in the drivers folder?

Download Arduino here: http://arduino.cc/en/Main/Software

Once extracted look in the drivers folder. They are all in there.

As Dean said, if that driver is necessary for communication with the Arduino, it will be in the Drivers folder.

[Gary Schwartz]

 

That worked after figuring out that the driver needed is  "Arduno.inf"

 

Dean posted after I did, so I didn't have his recommendation when I posted to you.

I've tried everything recommended with no change in symptoms (failure to connect).  That leads me to conclude that the ATmega16U2 chip on the Arduino Mega has failed.

 

Have I missed anything, or should I order a new Arduino Mega?

 

 

[Nicolas Duarte]

One thing that I haven't seen mentioned is to make sure that you are not running Pronterface and the Ardurino programmer at the same time.  If you are running the Ardurino programmer it will keep the USB port held.

From my understanding, you are in fact able to program the Ardurino is that correct?  Do you get any errors from the Ardurino when you try to program?

I have also had some issues with selecting the right USB port.  I am doing mine with a Mac but I have a long list of USB ports that I have to select through a long list that was confusing before I picked the right one.

[Gary Schwartz]

"not running Pronterface and the Ardurino programmer at the same time?"

Not running Arduino programming & Pronterface concurrently.

​

"From my understanding, you are in fact able to program the Ardurino is that correct? Do you get any errors from the Ardurino when you try to program?"

 

I was able to compile & run the "blink" sample program.  It runs whenever connected to PC.   Nothing else ... (I don't know how to program it).  In the past I was able to open configuration_h, edit & compile & upload it.  Now I can only open any file that has .pde extension.

 

When I start Arduino.exe it opens the "Sketch" tab.  What is a sketch in Arduino language?

 

When I Checked serial monitor I got "Serial port COM2 not found.  Did you select the right one from the serial port menu?"  YES!

 

Is there any way to make the tiny red-on-black error messages legible?

 

I'm ready to conduct any further checks, so send ideas. 

In the meantime I'm going to buy 20# of sculpting clay.  I figure I can get from AutoCad to prototype more quickly that way.

B) Replace MEGA

C) ????

One problem I could see is that you might not be uploading all the files.  With Marlin you have a main file that includes a whole bunch of other files that also get included.  If you program just the configuration file then you don't get the actual bulk of the program (unlike the blink example). When you open the firmware in Addition do you have multiple tabs at the top or just one file?  You should not be opening any files from the windows file browser but rather through the Ardurino open interface.  Try this:

Close Ardurino
Make sure your Marlin-Marlin_v1 (or whatever version) directory is in your Ardurino default directory
Open Ardurino
Go to the open sketch icon
Marlin should be there

You could also open the Marlin.info file from the windows file manager and should have the same result, but it gets sloppy that way when you want to do lots of changes.  Once you have multiple tabs for your sketch it should upload all of the files to the mega.

Good luck.

Nic & anyone watching

 

You were right.  I didn't have correct path specified.  That's fixed, I successfully compiled, but uploading still reports error. 

 

"avrdude: stk500v2_getsync():  can't communicate with device: resp=0x01"

 

Still unable to connect.

​

I tried S3DCreator after deleting everything associated with Pronterface & printrun.  All went well until I attempted to connect.  I was unable to connect.

 

FWIW it's worth, my Prusa experienced hotend temperature runaway ~ 2 weeks ago.  Cause not found.  New hotend worked OK.

 

Windows still reports that device is working properly.

 

Could a corrupted Python file be the cause ?  I see reference to Python in all printrun error log files.

If I learn that corrupted Python file cannot cause my problem it will be on its way.

Ok, I wanted to do one more trial before I leave home from my office and it WORKED! :D :D :D I dont know why and it doesnt have any logic but it works :D I wrote in my firmware #define SERIAL_PORT 3 but this is how it works :D

// SERIAL_PORT selects which serial port should be used for communication with the host.

// This allows the connection of wireless adapters (for instance) to non-default port pins.

// Serial port 0 is still used by the Arduino bootloader regardless of this setting.

#define SERIAL_PORT 0

Hope I could help :)

Kind regards!

If it helps anyone:
I was having the same problem as Gary and was able to resolve it by installing 'serial_install.exe' which can be downloaded here https://www.pjrc.com/teensy/serial_install.exe
Worked for me.
