Connection to EggBot extensions

[bernabap]

I don't think there is a bug with the extensions, isn't just trying to find an EiBotBoard?

As we are using something else I tried to change the VID/PID number at line 6 of eggbot_scanwin32.py file to FTDI vendor ID and product ID as I am using arduino nano and it does the job:

hKey = _winreg.OpenKey( hReg, r"SYSTEM\CurrentControlSet\Enum\USB\VID_0403&PID_6001")

For Linux I just had to change from "ttyACM" to "ttyUSB" at line 28 of eggbot_scanlinux.py file.

BTW, great firmware thanks for sharing.

Hi bernabyp,

you patch works as well, but problem is that different Arduinos have different IDs.

I still think, there is a bug in eggbot-extension, because in eggbot.py calls function "getSerialPort" which first calls eggbot_scan.findEiBotBoards(). If that does not find anything (which is right, because we do not have an Eggbotboard with proper USB-ID), it is supposed to execute function eggbot_scan.findPorts(). Which looks for any devices on serialports.

Problem is, that if findEiBotBoards() does not find anything, findPorts() is not esecuted. I do not really understand why, but that is the problem. If we comment out that block with findEiBotBoards(), everything works like expected.

Hello, i tried to run your arduino-software with inkscape today, but it didn't work.

• EggBotControl Release 2.5.0 date 2015-01-30
• your actual firmware
• I tried your patch and also the patch with the VID/PID of my arduino.
• arduino nano

The arduino is working, because I get the answer "EBBv13_and_above Protocol emulated by Eggduino-Firmware V1.4<\r><\n>" The Inscape Script is connecting my board (led flashing), but get a wrong answer, so it stops. "Unable to find an Eggbot on any serial port. :( Error reading serial data."

[SpeedGP]

I have the same issue with jtronics. I've been searching for hours with no success. Unfortunately I have little to no programming experience, but still trying to work through.

Thank you for your work on Eggduino, I really appreciate it.

Pid patching is not recommended method. Disable autoreset on arduinoboard. Evey board has its own instructions.

[SpeedGP]

Yeah, I was just about to post this. I just got everything working by using a capacitor on my Uno instead of the recommended resistor. Thanks for your prompt response. And thank you so much for all your effort on this project :)

Hello everybody. I want to make eggbot but I almost suffered a mental breakdown. I'm trying for three days and does not work.

• The first problem is when I try to install EggDuino returns an error. on the Internet I found the solution that you have to replace that void inline inline void. Then it was loaded onto an Arduino. If i type anything in serial console it won't answer anything.
• In inkscape I get message: Unable to find an Eggbot on any serial port. :(
  I searched the entire Internet and tried everything possible but no luck. I was try:

and

but without any luck. I gave up over all. I have Arduino nano clone with CH340

[duezero]

@bosko90 this worked for me EggDuino-master.zip

[bosko90]

I try these but: error: 'sendAck' was not declared in this scope

[bosko90]

Which version of arduino IDE do you use? and version of inkscape and eggbot extension?

[SpeedGP]

I have had a ton of problems with Arduino IDE, you have to use the exact right version, or else it doesn't work

IDE 1.8.0 -- eggbot 2.7.1 on linux (kubuntu)

[bosko90]

I have IDE 1.8.1, eggbot 2.7.1 on windws and eggduino from your link. no luck :( I try with nano and uno.

[duezero]

ok try this EggDuino.zip

[duezero]

I'm using a UNO stadalone

[bosko90]

ok now it was without error. But if i type anything in serial console it won't answer anything, for check serial comunication.

I have connecter 5V pin with 100 ohm resistor to rst

[duezero]

Have you tried different settings in serial monitor? I don't remember now which ones are correct.

Usually I use 1k or 10k resistor on reset pin in my standalone board but I dont think it's the problem

[bosko90]

now I was trying all possible baud rate and add 10k ohm resistor.. and nothing

[bosko90]

If I try arduino sample: Serial Call and Response it work normaly.

[duezero]

try setting " NL&CR 9600baud" and then type "TP". The response should be "OK"

[bosko90]

OK that works! thanx.. one step closer.. Inkscape still say: Failed to connect to EggBot. :( Hod can I fix code in "eggbot.py"? instructions that I found are for version 2.4.0. in 2.7.1. there is no such code.

[duezero]

The problem could be the reset pin. If I use an Arduino UNO board, Inkscape fails. Using an Arduino standalone (ATMEGA328 on a breadboard) with reset pin disconnected from the reset signal Inkscape works.

[bosko90]

Are you make any changes on Inkscape extension? Now I try 100 ohm and 10k ohm.. no difference..

[SpeedGP]

Have you been able to upload the firmware to the Arduino?

[bosko90]

Yes. In serial comunication I have response

[duezero]

No changes on Inkscape. Reset pin must stay always connected to 5V using a resistor, 10k is good (pull up). But shall be disconnected from the reset signal (which drives rst pin to ground triggering the reset) once you uploaded the program. You shouId try with a standalone MCU (or maybe cut physically the signal on your NANO but I'm not shure because I dont have a NANO)

[bosko90]

here is my knowledge of electronics ends. It shows that this year we don't have Easter :/

[SpeedGP]

I feel like I had this same problem....

I'll look through pictures and see if I can find anything useful

Now I have response: unknown CMD..

[SpeedGP]

I HAD THIS EXACT ISSUE!!!!!

I think this is how I fixed it!!! (Image attached)

You may be able to see my arduino behind it with the breadboard and stuff plugged in also...may help https://youtu.be/l_Jm1lLs5U4

This guy uses a nano and said he had some issues also. You should try this tutorial, or just use an Uno :P http://tomscircuits.blogspot.com/2016/05/a-low-cost-eggplotter.html

[bosko90]

thanks for the link. I already tried that but with no luck. I searched the entire Internet and tried every possible solutions. It shows that I am incapable.

[bosko90]

I will try with this second link

[SpeedGP]

Trust me, I had a ton of issue with the eggduino too....

Upload a different sketch to the nano and see if it's the board.

Did you try the Unicorn plugin or whatever?

Did you use any capacitors?

Have you tried a different USB cable?

Have you tried a different version of Arduino IDE?

[duezero]

You should try Arduino standalone, it's not difficult as it seems ;) https://www.arduino.cc/en/Main/Standalone

[bosko90]

I tried Unicorn plugin, but have a lot of errors in generating g code. I do not know with which program would then communicate with arduino. GRBL doesnt work. Now I do not have capacitors.

duezero: I don't have that much electronic. I am mechanical engineer.

[duezero]

I am mechanical engineer

Me too ;) trust me, try with standalone or try to cut reset signal on your NANO

[bosko90]

I do not know where to get all the components. Especially in time.

[Yura80]

Take a look at my branch ( https://github.com/Yura80/EggDuino ) for instructions how to patch version 2.7.1

[SpeedGP]

Here are all of the files I used in 2015 https://drive.google.com/open?id=0B6X9s6ncrqeqdHA2QmZnamFkeGc

I am not sure what worked, or why, but I'd assume your answer is in there somewhere...

I believe I used Arduino IDE 1.0.6 My Inkscape is version 2.4.1? something like that

You may try spherebot

Good luck. I'm out of ideas

[bosko90]

Yura80 where can I get VID/PID of my arduino? SpeedGP I will try..

[Yura80]

Device Manager->Ports (COM & LPT)->[your arduino com port]->Properties->Details->Hardware IDs

[bosko90]

I didn't find that.. but I tray:

alternatively, you can replace "EBBport = None" with your specific port number: EBBport = "COMxx" #Windows EBBport = "/dev/tty[something]" #Linux/Mac

change to "COM4" and it's wooooooork! for now. servo is moving.. Now I must connect the stepping motors. Hope it is work.. Yura80 thanx! and of course thanks to all of you I offer assistance. Now it is 8 hours behind me. If I need anything I write tomorrow.

[SpeedGP]

I guess we all assumed you had the correct COM port.... 51 did sound a little high, but who am I to judge. Glad you got it working!

No I always knew that is COM4. But in the extension for Inkscape I didnt know how to fix. your link has helped. Now I have to set the proper size of steps. The motor is rotated four times instead of once.

Hello to you all,

I'm new to GitHub and joined to talk with you about my issue. I tried everything you posted before and i also tried @duezero versions of Eggduino. With the newest IDE 1.8. I can't get his sketch to run through my compiler. It get stuck everytime by this Part and I dont know how to fix it. " Helper_Functions:4: error: 'SELFPRGEN' was not declared in this scope SPMCSR &= ~SELFPRGEN;

exit status 1

'SELFPRGEN' was not declared in this scope"

Do you have any clue what I should change to your Sketch to get it running?

Funfact aside: I tried "Ejjduino" the Eggbot Version from jjrobot and it worked fine on my ArduinoMEGA. I could also connect it to Eggbot Inkscape extension, after some modifications. But it failed to move.

[SpeedGP]

Duezero posted this last time: Try this one

https://github.com/cocktailyogi/EggDuino/files/767494/EggDuino.zip

Or

https://github.com/cocktailyogi/EggDuino/files/767445/EggDuino-master.zip

Other than that, try older versions of IDE

Probably MEGA2560 is not supported yet. I have the same issue if I try to compile for a MEGA2560. You need to use an Arduino UNO or NANO (ATmega328). IDE1.8.1 works fine.

Maybe I'll check later if it's possible fix this issue but you don't really need a Mega2560 for this project

[Asenom]

Thank you for your reply, yeah i know it's some kind of overpowered, but it was already laying around so i gave it a try! Yeah, i will try out some other trouble shooting in the evening! Thank you! i would apreciate it!
