Mount allows installing NVMe disk with USB enclosure on DIN rail in Voron 2.4 and then boot OS from it.
I'm using 2230 M2 NVMe disk (Samsung PM991A). USB enclosure ("no name" model) holes for securing bigger, 2242 and 2260 disks, are used to secure this enclosure on DIN rail mount (via two M2x8-10mm). Since disk sizes are standardised it should work on other USB enclosures with such mount holes, too.
How to boot OS on raspberry pi 4 from such disk?
- sudo raspi-config → “Advanced Options” → “Boot Order” → “USB Boot”
- clone your sd card content to NVMe USB drive (using “dd” for example or some windows cloning tool)
Connect disk to USB 3.0 or 2.0 port, start Rpi 4. It should boot from NVMe disk in USB enclosure (disk can also be SATA disk etc).
Why?
For fun, testing. Speed gain makes no sense for usage in Voron. The only thing that it makes sense in comparison to sdcard solution is better durability in case of frequent write (logs in debug mode or timelapses). There are dragons, too. USB 3.0 disk is able to fully saturate USB bus in raspberry pi 4 which can cause trouble for CANBUS latency if also run over rpi USB. Requires more testing in real case scenarios.
Additions:
In such USB enclosures disk is often secured using rubber pin. "adapter-clamp.stl" prevents it from releasing free.
