I have just fitted a Smoothieboard to an OX CNC 1000mm x 1500mm.
Things are going well, though I am in the process of modifying the web UI to be more CNC-like.
I have a question: Can I get the Smoothie to pause G-Code interpretation on receiving a Tool Change command?
I have another CNC with Mach3, and there I can set the machine to pause on Tn commands, so I can physically change the mill in the spindle. This is kind of useful for running jobs where I have a roughing pass then a fine detail pass.
