duet 085 sd card readings not consistent
Napalm1432 last edited by
I'm building a 3d printer using the duet 085 which i had still laying around, and am using the dwc too, i noticed though that it often happens that i get the error "can't read homex.g" for example, i then have to reset the machine for it to work correctly again.
Is this a hardware problem, or sd card problem or something else?
Also when using dwc it often has issues showing current states (for example having to refresh the page to see current temperatures) is there any cause/solution for this?

run M122 when it happens, and i'd pull the sd card and inspect the contacts

For some reason it took a while for it to happen again, but here is the log from M122
This is with a different SD card (a new one from SanDisk) and the same happens.

I suggest that you update the firmware. The last release available is 1.26.1 (which came with the 2.05.1 release)
There are likely some changes required to your config and homing files when going from 1.21 to 1.26 so take a look through the release notes.
At the very least updating will give us more detail in the M122 report.

Okay i have updated the firmware (just wondering is there another/newer version of dwc? running 1.22.6)
So far it seems like it keeps reading correctly, is there a way to keep checking if the sd card can be read every x seconds, without having to be constantly checking manually

Not really. See here for testing SD card function: https://duet3d.dozuki.com/Wiki/SD_Card#Section_Troubleshooting_SD_Card_issues
