Hiya, yes the wiring is confusing.

most of mine is in a pile along with original electronics.i have used some of the cables to retire up my machine.

i am using a BOB board as I said earlier in post. The one I used has a 10v speed out for the spindle so I didn't need the spindlev4 board I bouht in the end. I blew a BOB board prior so went and bought some new ones.

the dspindle lead 3 to 9 is for the door lock, but as I have wired it currently, it only stops the spindle and the machine still currently runs in axis so sure way to break tool bits! I have it going 3 to front control panel chocblock where it is wired into the door interlocks, then returns to pin 9. I'm sure there is some link to emergency stop I should put in but I need to investigate this.

the 3 resistors I believe reduced the current going into the power into the relays to stop them burning out when in operation.

the mains filter feeds supply to the spindle controller and the lights so your correct there.

2 big blue caps are wired together and provide 18v dc, the other is 28v dc, you can get rid of one of the 18v dc caps and just use 1.

the relay is for the lights. handy to keep hold of it to fit later on, as provides good lighting to the unit. However prob easier to fit lights on when machine is on and bypass relay, or to fit 24v Led lights and run off 18v? Again to run continuously.

the spindle sensor is an optical unit, and unless you have some custom electronics to display spindle speed, or wire it into your controller, it's not necessary.

on the spindle controller, the are 2 rotary dials which adjust the lowest speed, and highest speed. I set mine up when it was running, but be careful, as its mains! Looks like your cover isn't with the machine, the orange plastic cover.

ground from the mains is earthed to machine the big aluminium plate. Live goes from the input, to the key switch, then back to the reset fuse the green and red button thing on the side, then back down to filter and spindle. I have my complete wiring diagrams at work, so will add them to my Flickr pool for you to see.

will post this as I can then see what else you have said and I can reply again

I have found some information on the door interlock...

It seems most people wire a connection across pins 3 and 9 on the speed controller to bypass the killswitch, I would guess that you could wire your E-Stop and door microswitch in series between these two pins depending on if they are NO or NC.

Sorry cant help with the resistors, does your machine work without them wired up to anything?
