I have a new Chinese import Router, controlled by Mach3. After some experimentation, most aspects seem to be working fine. However, the spindle does NOT start when simply pressing the "Spindle CW F5" button. Yet, the yellow rim around the button starts blinking, indicating that the spindle should be running. When I click it again, the blinking yellow rim disappears and the spindle stops (the spindle actually turns a little bit before stopping completely). This behavior is very similar in code: M3 S10000 doesn't do anything, but an M5 AFTER that makes the spindle rotate a little before stopping. M5 without being preceded by an M3 doesn't do anything. So far, one might think that some pin wasn't set correctly or a connection fails. Yet, the strange thing is that we can actually use the router! This is done by removing all "M3" assignments from the code and starting the spindle manually. Starting the spindle manually requires a DOUBLE-CLICK on the "Spindle CW F5" button (yes: double click starts the spindle normally, single click doesn't work). When the spindle runs, an M3 assignment in the code stops it again?! That's why we remove all M3 assignments.
    =>  Single click or M3 code: spindle doesn't start but the button starts blinking (yet something happens because M5 behaves differently).
    =>  Double click: spindle starts normally while the button blinks (M3 stops the spindle, as does M5).
Accordingly, we have the impression that the machine works fine and the problem resides somehow in the software. We have searched and read a lot (and learned a lot too) but yet without a solution. :'(

Any help is highly appreciated.
