Curious if I need to adjust anything here.
In this image, the torch head has just rounded the corner and is headed down and back to the finish point of the path. The torch head was black for the whole cut until it round that corner, at which point it turns red and stays red till it finishes.
Check your Stock height and thickness in the setup area for the job in Fussion. The red means that the software thinks the “spindle” is going to crash into the stock. Since we’re only doing 2D cutting it’s not normally an issue but if you want all green start there.
