Solved Unable to connect to printer in MC or Arduino

Hello. I attempted to update my firmware through multiple versions of arduino and it seems that somewhere along the line I messed something up. The printer still connects to my computer through USB and under Device Manager the device shows up as being connected through COM4, however in matter control and arduino it states the port is already in use. To the best of my knowledge, that's incorrect...it isn't already in use by anything, I've gone as far as uninstalling all versions of Arduino I had on my computer including all the libraries, I've closed any software that could be running in the background, and restarted my computer as well as the printer countless times, I've also tried switching to different USB cables with no success. I've tried connecting with a few versions of Arduino (New, old, middle of the road). I'm honestly at a loss on this one. I'm not sure if perhaps the board got fried, I don't think so. I popped open the back and the arduino has a yellow light, when I plug/unplug the USB cable a green light comes on quickly on the Mega 2560, as stated above it still shows up in my device manager, but the port is getting noise, or it's just being tempermental/doesn't want to connect anymore. At this point it's not as simple as just 'factory resetting' with stock firmware because I can't do that because it doesn't connect.

I'm not sure if there's an error log I can provide or any other details, I'll try to be as specific as possible for you so it's not a pain to help me. If there's anyone out there who's more seasoned than I am that could shed some light on this, or make any recommendations on how to force a connection or force a reset of the board itself that'd be awesome. Thanks a ton to anyone willing to take the time to read this and help me out.

 

Sounds good. Thank you both for the speedy replies. I've gotta get to work soon so I'll post a reply this evening when I get an opportunity with the requested information. Thanks again!

I hope this helps and again thank you guys for taking the time out of your day to read through these logs which I don't fully understand. I hope it yields the information you are looking for and hopefully gives some results on what I need to do here to get up and going.

Thank you!

 

Thank you all for the replies. I'll give it a shot this evening and see if I can get some results. Worst case I'll just buy a new board, mega 2560's are pretty cheap, I just hate to replace things when I don't have to.

 

This sounds a little familiar from here and here.

 

Steps taken in an attempt to resolve:

1. Viewed all links posted in this thread
2. Read over all solutions offered
3. Found a solution which made the most sense/seemed tailored and relatively guided to the proper info needed
4. Downloaded Windows device drivers for Arduino UNO from: (Link Omitted)
5. Drivers were already installed however I considered the possibility of a bad driver, so I uninstalled and then proceeded to reinstall
6. Uninstalled old versions of Arduino IDE
7. Installed Arduino 1.8.3 IDE via the windows installer (Current/Most Recent version as of today 8/3/2017)
8. Loaded the ROBO3DR1PLUSV2.ini file into arduino (I made sure this was the R1+ version, not the standard R1), file was downloaded from: (Link Omitted)
9. Selected Arduino/Genuino MEGA 1280/2560 in Arduino 1.8.3 IDE
10. Selected the MEGA 2560 processor
11. Selected COM4 (Port listed under ports in Device Manager and the one that shows up in Arduino 1.8.3 IDE)
12. Left the programmer the same (AVRISP MkII)
13. Verified the file after loading in Arduino 1.8.3 IDE
14. Received the following error message:
15. [[[To be determined]]]

I do recall reading somewhere about fpos_t no longer working and to change to FatPos_t and that may correct the issue, however I am not going to do that at this time and leave it to you folks who are better versed at this to analyze the error and make a recommendation. Thank you all again for taking the time to reply and help me with this.

 

Here's the one about the C++ error: github
(Needs a single space before MSG)

Code:

LCD_MESSAGEPGM(MACHINE_NAME" " MSG_OFF".");

 

I did actually check out that thread, I was reading through some old threads a few days ago and passed over it, interestingly enough. I went through the file and replaced any and all instance of fpos_t that I could find with FatPos_t. I'm pretty sure maybe I missed one somewhere because when I verify the file it's still giving me some errors. @mark tomlinson Would it be any trouble for you to post or direct me to where I can find the repaired firmware for IDE v1.8.3?

Thank you all again for the help and your replies it's really appreciated.

 

Oh you're quick. Alright I am gonna give this a shot real quick *rolls out of bed*. I'll get back to you on this in a few minutes.

 

(I am sorry in advance that I am so much trouble hahaha, one thing after another here). I feel like I'm making progress however now I am getting this error upon verifying the file. It does appear it is able to connect to the COM port now, I think reinstalling the broken drivers for the Arduino UNO fixed the issue, however along with the original fpos_t error I was getting an error from what looks like watchdog.cpp and marlin.h from #define Y_MAX_PIN, X_MAX_PIN, and Z_MAX_PIN. It states they are redefined, I cannot seem to tell if this is an error or if this is normal for the compiler. Here's the error:
