I received the Arduino Nano and now, that works very well.
I have uploaded the firmware Grbl from github (the last) with Xloader and it's perfect.
Thank you very much for your help and thank you @Zax
Yes, I tried diverse baud rates, 115200, 57200, 9600, 37... but nothing works
I have no return with the baud rates different than 57200 even if I wait 4 hours.
Thank you very much for you advices.
I played securely and I have bought a real Arduino nano on the official website.
I look for an AVR programmer too, that seems to me very useful like you said me.
I will reply when I will received my arduino nano, I hope that will works.
Thank you very much for the help.
I tried the option to change the speed but the time is very long (since 1h30) and seems to not work, I have a red LED and the XLoader show "Uploading..."
The Microprocessor and the Post Processor are already set with the good values
It's normal that my card is not really an arduino nano card ?
I tried different USB cable and reinstalled the driver but nothing change, always "upload failed".
I have checked my card but I don't have a reset button on the Nano like (ATmega328)
I will try the solution to load the boot loader via ICSP connector.
The solution will be to change the nano board ? like https://store.arduino.cc/arduino-nano
Thank you for your answer.
I have downloaded Xloader and the firmware 1.1f on https://github.com/gnea/grbl/releases
After the installation, I tried to upload the firmware and the result of the Xloader are "Upload failed"
Do you have an idea ? how can I reset the Nano card ?
When I try to install firmware from T2laser, I have these errors:
Thank you for your answer
I have bought an Eleksmaker A3 pro and I was used it with "lightburn" until I test T2laser.
On T2laser I tested to change the firmware but that created problem because now, the laser not really works, the result is always "upload firmware error 1/1" or "1/0" for the default firmware.
I'm very disappointed because now the laser clearly not work.
The laser works and the Y too but the move X not work.
