This is documented.

I'm confused by how docker-compose decides to name volumes, prefixing a garbled directory path to the volume name. Consequently if you rename the directory, a new volume is created.

So I wanted to export the volume contents as a .tar.

MOUNT=/usr/share/elasticsearch/data; \
for VOLUME in {mariner,data_parsers_mariner,optdata_parsers_mariner}_elasticsearch_data; do \
    sudo docker run --rm -v $VOLUME:$MOUNT -v /data/backup:/backup ubuntu \

tar cvf /backup/$VOLUME.tar $MOUNT; \

Flashing Marlin to a Monoprice Maker Select V2

These notes were written March 2020, and may be out of date. I'm flashing Marlin 2.0.4.4 using a Bus Pirate from macOS Catalina.

Support for the Monoprice Maker Select V2, aka Wanhao Duplicator i3 V2.1, has been merged into Marlin, so you should not need to find any third-party code or mysterious config files posted to Reddit years ago.

Install prerequisites:

brew install avrdude platformio
