Welcome to the SeeMeCNC Community

Mine didn't come with a working bootloader either. I used my Bus Pirate to program it. A bit odd, yes, but I figured I'm learning more about how the machine works... Great job with that bus Pirate !! Just one thing, I expended, taking into account the shipping costs plus fees at customs, more broke...

Finally past friday I received the avr programmer. Today I have flashed the bootloader and now i can modify or upgrade the firmware without problem. So I have to add one more thing to the list of problems encountered in my kit purchased at SeemeCNC sarcasm /On SeemeCNC Thanks. sarcasm /Off Greetings...

Thanks every one for the help ... sarcasm /On seemecnc especially for having put things so easy. sarcasm /off

Read all you can about reloading the bootloader before attempting it. To search everything in this forum enter this into your browser: site:forum.seemecnc.com bootloader This will tell it to search all of the seemecnc forum for the word bootloader. Handy to use. You can search for any word. I do ho...

Sarcasm is not necessary. Friendly communication is. If I had known that you were in Spain, I would not have suggested returning the board to Seemecnc. As far as the other defective parts, I feel for you and Seemecnc should not have sent you defective parts. I do not work for them so I can be of no...

Hello lightninjay I alrready have tryed selecting 7th option. Long time ago, I have been experimenting with an Arduino One Board. This board in the bootloader time, blink a led atached (in to the board) to the pin one, during ten seconds to show bootload time. Well if i attach another thing to that ...

Ok, this may seem trivial, but you aren't leaving the board connected to repetier-host while also trying to simultaneously connect to Arduino, right? Because in that case, both hosts can't simultaneously communicate with the card. If ANYthing else on your computer is trying to read/write to/from th...

Sarcasm /On Ok I will send from Spain, my Rambo board to upload the bootloader, also the pulleys alone broken without being installing them on the machine., and the power switch that has insufficient power to heat the extruder and the heated bed simultaneously. I think that I was very lucky with my ...

Ok

Well, I'm finally almost convinced that my motherboard does not have bootloader, sure it has been programmed with a programmer, wich don`t need the bootloader. I think this because the startup is instant. So I have 2 choices. Buy a programmer, like AVR-ISP or try to install a bootloader with a paral...

Is your RAMBo board powered while programming (are the 12v input rails powered?). If not, the AT MEGA 2560 will not be powered and the programmer can't communicate with it, resulting in the error you're having. USB power only powers the programmer. Yes it has powered by a PC power supply conected t...

250000 bauds is the default speed, and yes I change with LCD to 115200. If not, we can't see anithing intelligible in the serial monitor.

Only a update from my last communication... I have attached a captures from my desktop. You Can see that Serial monitor is reading from Rambo board, also I have included the Rambo Board in the board selection menu, and last I have changed comm port to 10. Without progress... conclusions: Arduino com...

Hi again guys and thanks for the help... That is true. But if it were totally messed up, you would not be able to connect to it. Is this the rostock or the orion? It is the Rostock Max 3D v1, version of repetier is 0.80 I have run into this connection issue sometimes with Rep-Host and the Arduino de...

Got that from the RepRap wiki, there is an add-on that needs to be installed. I don't speak spanish, hopefully translate works well enough for you Don`t worry Nylocke, I understand very well English, but is not so easy to me to write it, so some times I call to google translator to help me :? Yes, ...

Yes, as the tutorial say.... --> Tools Menu --> Board ---> Arduino Mega 2560 or Mega ADK Comm port in my case is 3, and I have no choice of select another, when I plug the usb wire, Arduino autoselect the comm port. Spanish: Si, como dice el tutorial... ---> Menú Herramientas ---> Placa ---> Arduino...

Yes, of course, I don't know what can I do more. Most of Arduino boards, has a bootloader, to let users without a programmer device, upload his programs to the boards with a standart USB or Serial RS232 wire. Without this bootloader, the only way to upload is with a programmer device. I'm beginning ...

I think yes, I have selected Arduino Mega 2560 or Mega ADK and Com port is 3, I have no choice for last one and if I unplug USB, this option dissapear from tool menu. I have trying to upload firmware with an standart usb wire, same that I'm using to comunicate with repetier host software. And of cou...

Hi guys, I have this problem. I must correct some parametres about Z0, such as #define Printer Radius. Each time that I try to load new firmware to the Rambo board, i have those errors: avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveM...

... Continuando con el problema de que no consigo modificar el firmware de la tarjeta RAMBO, esto son los errores que me devuelve cada vez que lo intento: avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk5...

Hi guys, and thanks for try with Spanish ;-) Well, i have latest version of arduino and drivers for Rambo. in fact repetier host software it communicate to Rambo board without problem. My printer, has a little deviation with Z0 in the centre of the onix bed, so I must adjust the printer radius varia...

Hi guys My name is Oscar and i am writing from Spain. A few weeks ago i finished the assembly of my Rostock Max 3D V1. Now i am in the phase of calibrating and printing the test cube. Recently i have changed cristal dish over the heated bed, and i have to re-calibrating the axes, and i have a little...

Hola a todos, parece que este va a ser el primer mensaje en este apartado del foro en Español. Os escribo desde España, hace pocas semanas que finalice el montaje de mi Rostock Max 3D V1, la verdad que me ha llevado mucho tiempo, mas del que yo hubiera querido, pero entre que no disponía de mucho ti...
