Can you attach your xml. Also not sure if you have said but what kind of drives are you using?

Is that because Mach3 won't run on a 64 bit machine?
What did you use for the wire guide?For the heavier (0.7mm) wire I wind it needs to be sort of decoiled so I made up a series of 3 delrin rollers that the wire snakes round, this seems to straighten the wire out and keep a bit of tension on it. For thinner wires I dont use the rollers, I just feed straight off the coil. The nozzle part is actually a mig welding contact tip for the heavier wire and for thinner wire I have a delrin nozzle that slips over that with a hole to suit the wire dia being wound at the time.
What do you recommend for varying the traverse feed rate throughout the coil?Not really sure what you mean here. I dont vary the traverse rate at all, the Z axis moves back and forth at a constant rate. It does slow down, stop and reverse obviously but Mach should keep the rotating axis in sync with it by slowing it slightly, it is hardly noticeable though.
I feel confident writing the code, but would rather have the machine copy my more subtle manual moves. Last question, are there any reccomendations you could suggest for trying to record the manual movement of the motors?
Also, I'll be using a laptop to run Mach3, so what plugin would you reccomend to control the spindle and traverse.If using a laptop that has a parallel port then you may be lucky and get it to work, some laptops are ok but the vast majority will have timing issues due to their power saving features. You can get round this by using an external pulsing device, the SmoothStepper is what I use and it connects via USB.
