Synthetos board does not respond

Hello, thanks for the answer.

At my first connection, following this wiki page https://github.com/synthetos/TinyG/wiki/Connecting-TinyG
I received the expected response (an Json {"r":...} response enveloppe) but I don't remember the content.

Then I unplugged the power and assembled it into my enclosure.
After that, I tried the exact same steps (coolterm, 115.200 bauds... so on), and I do not have any JSON answer. The serial port is listed, and I manage to connect to it, but the board remain silent.
I even tried with tgfx which is stuck at :

"
[+]Connected to COM5 Serial Port Successfully.

Getting TinyG Firmware Build Version....
"

I already tried to update the FTDI drivers, try to restart my computer, reset the TinyG board, change US§B cable. Nothing works.

Updating firmware gives me an error :

avrdude.exe done. Thank you.

Ok got it to work.

Reinstalling firmware (with same version did the job).

Previous error was that while downloading, Windows changed the format of the file from Intel Hex to Binary Raw.

Is it possible to only download the latest firmware at the correct format, without cloning the git repo ?

Thanks

Riley,

Thanks but for some reasons, the link you provide don't work. I mean, when I do "Register as" in firefox, the MIME type of the file change. It was recognized as a binary raw by AVR Dude (and the size of the file was around 900ko). I had to download the full repository as a zip file to have the correct MIME type. It was then recognized as an Intel Hex and worked perfectly. I moved to the edge version of the Firmware.

Regarding the process for a non responsive board, I think I told you everything. The only thing I did to fix was to reinstall the firmware (the exact same master version) and it worked like a charm. I even managed to get my motor to move. I still have to set the correct values in the setting.

I'm running a custom Shapeoko :

And the enclosure is

I won't be able to post pictures, since I'm away from my workshop for at least 2 weeks now.

Thanks for the help.
I can't wait to test my TinyG board. I was using Grbl (without issues) before and switch for the 4th motor support and the configurable microstepping that's lacking on Grbl.

I'll keep you in touch
