I don’t know, in my opinion the failure happened while sending the new calibration dataset to pop3, not during hovering over the board. But perhaps: bad light - bad data - bad processing… ---

Maybe there is another explanation: i don’t know of the power plug of my laptop was in. Normally i have best performance also running on battery in the settigs, but who knows if the usb power was reducued a little bit. Anozher guy in the forum told about this problem while trying to calibrate. ---

If you running just one cable for power and data then my answer is no , I run 2 USB cables one for power other for data , never issues with firmware updates or calibrations ever again , even if both cables are connected to the PC … use the split mobile cable and get yourself some extensions. I have 13 ft USB and works as charm [Previous page](https://forum.revopoint3d.com/t/pop-3-calibration-data-processing-failed/21695.md?page=1)
