Hi recently my snapmaker too started to behave in a strange way basically it loses calibration data.
I put the machine I go through five-step calibration until the end.
Everything looks fine i am taken to the home page on the touchpad.
Ten as lect File from USB pendrive and try to printe but then I get the message
“The machine hasn’t detected any calibration data”
I try to do the same but reboot/power-cycle after the calibration. After fresh start intry to print and I still get the same message.
I’ve ever had any problems with previous versions of firmware - now I’m using the current one v1.14.3_20220617
