SD on DuetPanel does not read with accelerometer
-
Hello, I have a problem with reading the SD card on PanelDue, after installing an accelerometer above the Thermocouple daughterboard, it no longer reads the SD card if I remove the cable, why does it work? Thank you

@Daniel-0 it's because of the extra capacitance of the accelerometer cable, which uses the same SPI bus as the external SD card.

@dc42 Isn't it possible to disable the use of the accelerometer via firmware so that I don't have to open the printer to plug-unplug when I have to use it?

@Daniel-0 It's the cable itself that is causing the issue, not the accelerometer. There isn't really any other option other than disconnecting the accelerometer cable, at the Duet end, to stop signals bouncing up and down it and interfering, at least as I understand it.
