Grid:Host -- multi-target file sender

Grid:Host is a multi-target file sender with pluggable gcode translation. this is primarily intended as a print target for KIRI:MOTO to enable sending of files to networked 3d printers and cnc mills.

It is different from OctoPrint in that it is mainly designed with multiple targets in mind rather than acting as a host for a single printer. It is vastly simpler to setup and run delegating the more complex integration tasks to modules or external programs like Octoprint.

Usage:

bin/grid-host [options]

Options:

--port Port for HTTP (defaults to 8081)

--https-port Port for HTTPS (defaults to none/off)

--ssl-cert File path for SSL server cert (required for HTTPS)

--ssl-key File path for SSL server key (required for HTTPS)

--config path to config file (overrides command-line options)

--target device target in the form [name:host-name-or-address]

Sample Config File:

rename etc/config.json.sample to etc/config.json

currently built-in filter types:

  • gx - flashforge finder printers
  • n2 - raise3d n-series printers
  • x3g - gcode to x3g conversion using GPX for Makerbots
  • scp - file copy via scp to host target
  • post - http post to target (flashair wifi sd cards, etc)

Generate a Self-Signed Cert

openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout etc/ssl.key -out etc/ssl.crt

Generate Certs using Cerbot

certbot --text --agree-tos --email your@address -d local.grid.space --manual --preferred-challenges dns --expand --renew-by-default --manual-public-ip-logging-ok --config-dir `pwd`/tmp/cb --work-dir `pwd`/tmp/cb --logs-dir `pwd`/tmp/cb certonly

Starting Grid:Host

bin/grid-host -config etc/config.json
