Hey Now! Let's not get down & discouraged!
I think your problem is that you are using Pin 17 for your Router. Usually Pin 17 is reserved for the charge pump signal. Try putting your router on Pin 16.
IMO- this is not entirely a Mach 3 config problem. The Mechatronics controller manual is not very clear/thorough in explaining how to wire up your system, so you are left to guess. Not really your/Mach's fault. Mach is designed to be used with a myriad of controllers/BOBs and is flexible enough (configuration wise) do deal with most of them (including yours).
Bottom line..."Easy-Cnc.com" ISN'T very easy
HTH,
