Trigger cable lowers temperatures & power consumption

[Freddie77]

Have you tried different SD cards? The Devialets are compatible only with the older SD cards (typically up to 2GB) and SDHC cards (typically 4GB-32GB).
If you're using a newer SDXC card (typically 64GB+) it likely won't work.

Also make sure you format your SD cards with FAT or FAT32 filesystem (not NTFS or exFAT).

Yes, all the new configurations I have tried have been wit the original Devialet sd cards; the configuration that is in use is with newer cards. I format the cards every time I try a new configuration. I think the issue is related to the configurator page.

So do I. 
I remember, some time ago when trying to download configuration files, that once the master config had downloaded, the companion config would fail to download properly. Please try this: Remake your new configuration from scratch. When you have done so, ignore the master configuration (which in your case seems to be OK) and download only the one for the companion, which I think is the one that is not downloading properly and is causing the malfunction.
Good luck with this, it must be driving you up the wall.

I haven’t tried that method, I will give it a go and will come back with the results. Thanks.
