Getting Started - no tool

bought a little mill of ebay to do stencils. found a low latency motherboard, set up stepconfig. no home switches right now. LinuxCnc doesn't find tool. Any suggestions?

Your G-code is probably referencing a to that is not in the tool table.

Can you run the AXIS splash gcode that is on when you start Linuxcnc? If yes, then Andy is right, your gcode is requesting a toll that does not exist in your tool table, but you can add it. Go to File>Edit tool table> add the tool number and other info.
