@logan which firmware are you on?

You should be using .67

@marcio do you know what version this was fixed in?

It looks like .49.

Logan, look at your console and see what errors are getting printed. It must be failing to save to EEPROM, and the console will tell you why.

I was on .67 yes
I confirmed the same thing on @EricNugent's machine but @matth's machine retained the data. We should all be on .67.

Once my machine is back together next week I can try again


Three things to try:

1 - Check the serial console for errors when running M500
2 - Restore Factory Settings.
3 - Erase the SPI Flash Chip:
     - Go to "About Printer"
     - Touch the "(C) 2018 Aleph Objects, Inc" string
     - From the Developer menu, click "Erase SPI flash"

Tried the steps to reproduce and my machine, Quiver 1, retained the backlash values after power cycling. I'm running .67

Testing on Marlin my backlash values are saved automatically after running calibration, and they retained the values after a power cycle. Going to close this one out.
