Yes I know but as I said earlier you need to have the relays enabled even if they are set to outputs you are not using and also you need to tell Mach the spindle has started by either commanding a M3, M4 or pressing the Spindle button. If you dont have either of these then you will not see the spindle speed displayed. This is just when using the parallel port though, if using an external device such as the SmoothStepper then these steps are not needed.
