How to use Xloader to load a new version of grbl into the Arduino/X-controller.
The left screenshot shows the window that Xloader displays when it starts.
Enter the file path or browse to the .hex file that you would like to load into the Arduino/X-controller.
Select the device type you are going to load into (Uno/ATmega328 for the Arduino/X-controller).
Select the COM port where your Arduino/X-controller is attached.
The baud rate should be 115200.
Press the “Upload” button.
When the .hex file has been loaded into the Arduino/X-controller the right screenshot will show the size of the file uploaded, or an error message if the upload fails.
Some telecom devices can be rendered inoperable by firmware updates that fail, which has given many people a bad feeling for firmware updates.
If the firmware update on the X-controller doesn’t work right, grbl will not be runnable, but you can reload the firmware as many times as you would like. The X-controller doesn’t lose it’s ability to update the firmware by a failed update.
Many days I do this procedure multiple times to switch among grbl versions in helping people with their machines.
Larry,
Thanks for the help and files.
Maybe this evening I might give it a try.
In pdf is says to make a copy of the current file that’s in the xcontroller.
How do I do that?
Ok,
I did as instructed and opened up picsender, clicked on Grbl, then clicked on Grbl settings.
I highlighted the text and saved it as an excel file with todays date
How can I open up the new hex file and just do a comparison before I run it through the Xloader?
You can’t really look inside the .hex file. Here are the grbl spindle parameters on my machine. They are close to the defaults, with some options that I use (500mm machine).
All you had to do is select Save in the GRBL menu like I explained. When you select Save, it will open up a window to save/backup the grbl settings to a user named text file.
The Save is for backing up your original grbl settings. If you want to recall them, select Open, select the file you saved and then select Send. I will restore all of your grbl settings back to the original ones.
