Forest CNC Set Job Home

REMEMBER To Reserve Time!

Various tools such as the lasers, 3D Printers, and Forest CNC need to be reserved before using the tool. There is a link on each tool's wiki page, and in each tool's Slack channel to reserve time, or you can select the tool from the MakerFX PickTime page

Note: As of March 2025, we are implementing PickTime tool by tool - review the Slack channel for each tool for current status.

How to page for Reservations
