I am contacting you because the CV calibration does not want to register. I turn on the module by pressing REC, I change the height of the voltage to +1 for example, and when I press X, I go back to the main menu but the changes are not saved … have tried 20 times with different options, I installed several drivers but nothing works …
What can I do ?
I am currently on the 1.71 driver
hmm, Ive not done this for a while - but it used to work
(but honestly, I don’t want to screw around with my calibration to test it now … sorry)
as you say, you just exit with X and it saves it…
I do remember some issue at some point with saving…
I think Squarp told me to remove the calibration file that sits on the sdcard and try again…
BUT I may be wrong, so make sure you back it up first!
honestly, Id contact Squarp via the [contact page](https://squarp.net/contact] on their webpage, and ask them what you can try.
