iSpindel Offset Calibration
Please note, that the offset calibration won’t save unless you go to the configuration page and press save first. If you hook your D1 mini up to the Arduino Serial Monitor you can see that it throws corrupt config file errors if you don’t save configuration beforehand. These errors are not visible through the user interface. Saving configuration creates the config file on the D1 mini and give the iSpindel somewhere to save the offset calibration. If the config file does not exist before offset calibration, everything will look fine but the offset values will be lost when the iSpindel is turned off! This is true for firmware 6.2.0.
Connect to the iSpindel Wifi network. I’m using Windows 10 but any device should work.

We’ll go into Maintenance.
I tried to do an offset calibration but the values wouldn’t stick. I then tried to update the firmware via a USB cord and the flashing program that I used in my first iSpindel Firmware Flash post, this post will have links to everything you need to flash your iSpindel with the most recent version of the firmware. However, I ran into issues with my iSpindel not being detected via USB cable so I instead used the wireless Firmware Update function from the iSpindels’ Maintenance menu (this issue was related to the USB cord I was using, later on, I tried multiple cords until one worked). Once I updated the firmware via my local Wifi network the offset calibration worked as expected.
After offset calibration is completed you can check the tilt value from the iSpindel Info menu.
The tilt value is 89.96° which is right where it should be. Ensure that the tilt is the same after powering the iSpindel off and back on again.
