I think I know this answer already, but is this possible? Looking to add the CNC Depot FM30 setup with 8 tool station but I believe I need a new controller running Mach3/4? Thanks in advanc .
Refer to Toolchanges · Issue #26 · OpenBuilds/OpenBuilds-CONTROL (Work in progress but been a couple months since we had time to work on that feature) However, Grbl itself won't support controlling the Toolchanger, so you are probably going to want to move up after all
