    Hi, new starter is having trouble upgrading from 0.9 to 1.1. I have a woodpecker board on a Chinese machine and it has been running normally with 0.9 loaded. I want to upgrade to 1.1 but I either get a message "upgrade failed" in xloader or xloader freezes while it is saying "uploading". I only have one comm port listed and that is the one I am using with version 0.9. I am keeping the baud rate the same. I have used different copies of xloader and version 1.1 but with no luck. Can anyone help me? Please

    You might try the Arduino IDE and download the grbl source code. Looks like the target would be Arduino Nano - Atmel 328P (if I'm looking at the correct board).

    Hi Scotty, thanks for your swift reply, I checked the board you mentioned but It's nothing like mine. I will hopefully upload a picture of the exact board.
    I managed to flash 1.1 but now I get an "unknown" message and nothing works. I have tried to go back to 0.9 but all I get is "upload failed" message.
    I have emailed the supplier so hopefully I may get an answer from them but as it's in China I won't hold my breath.
    This is my first venture in to these machines so I'm a bit in the dark at the moment but I'm learning. One other thing I would like to know and that is, is it possible to wipe the board of everything and start again?

    That is the board I looked at. It has the atmel 328p chip (Arduino Nano), so that is the target you should use if flashing using the Arduino IDE. I still suggest going that route. I can't promise it will work, but that's what I would try. And yes it's fine to start over.

    You will need to download the Arduino IDE from Arduino - Software . Then you will need to download the grbl source code from Releases · gnea/grbl · GitHub . Then you will need to carefully follow the instructions at Compiling Grbl · gnea/grbl Wiki · GitHub (Xloader instructions for windows at Flashing Grbl to an Arduino · gnea/grbl Wiki · GitHub but I wouldn't do it that way).

    I managed to load 1.1 using the Arduino but still got the same result as I did using the Hex file. The up/down, left/right and spindle control buttons were greyed out and I had the word "unknown" in the box where it usually says "idle or running. I have found 9 different Hex file versions of the 0.9 for the atmega 328 so I tried the latest and it did flash but all the controls are opposite, left is right, forwards is backwards etc but I cannot swap wires round as on most boards because this one has plugs connected both ends of the wires. I think I will have to try the other 8 revisions as a trial and error to see if one will work.

    A lot of hours searching and I finally have 0.9 running ok. I have given up on 1.1, it just doesn't want to work with my machine, I will stick with 0.9. The solution believe it or not was that I had to open the Laser Lightfire software that also came with the machine and check all three axis boxes to reverse them. I had'nt even looked at the laser side of it as Iv'e been experimenting with the mill.
    Thanks Scotty, you did put me on the right path and you did confirm what board I have. Lets hope it keeps running smoothly.
