GCode Variable Persistence After Power Cycling

ChunkyPanda

What is the best way to retain the value 16 arrays that will be restored after power cycling?

I have sixteen X & Y values I use for calibration for a project I'm working on. I declare the global variable in a macro and the value gets written and read from various other macros.

if !exists(global.xy_offsets)
global xy_offsets = { {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0} }

All is working ok, except when I power down, the values are gone. What's the best way to keep these values?

Thanks.

@ChunkyPanda
I would suggest that any time you change the values you write it to file.

Then call that file as a macro in config.g

e.g

; some changes were made so save to file
echo >"setOffsets.g" "global xy_offsets = " ^ global.xy_offsets

Config

M98 P"setOffsets.g"

@OwenD Exactly what I was going to suggest!

@OwenD Thank you so much! That's exactly what I was looking for.
