Got a new question. Come to run a program and it sits waiting for the spindle speed to increase. I don't have a spindle encoder, and do not have an input for one selected in the LinuxCNC stepconf. The documentation says if there isn't one then LinuxCNC should just simulate it anyway yet it isn't. I can't see any options in the HAL configuration and can't work out how to add the simulate encoder option in. Can anyone help with this one?
