So this is where i need abit of help as i have little experience of machining wood. I'm running X and Y axis (maybe Z ) with pulleys and belts as i need to keep the machine within the foot print. Ive got to keep the 1605 screws and wonder which pulley setup would give me best performance for 3D milling , so i would appreciate some ideas

Well I run 2005 using 1:2 on X & Y direct drive 1204 on Z axis and I'm happy with it in all cutting conditions.
I run 3Nm 34's with 76V on 80V 203v's maxing out around 11M/min but I don't run it at these speeds, I keep it to 7M/min for stabilty against missed steps etc plus it allows me to have higher Accelleration which you need for 3Dwork and deliberatly do it for this reason.
You have 23's on smaller dia screws so should get higher speeds.? . . BUT . . personally I think you'll be slightly restricted by the G540 and it's 50V max, which realisticly means 45-6V.!
To get best from the 3Nm 3008B they work much better at 65-70V and seen has it's mainly wood use then speed helps here.
Yes you can gear it for speed but higher the ratio less the torque and that gantry will be heavy needing good amount of torque to control the high inertia from Accelleration and De-accellerations required for 3D machining so bigger drives would certainly help and be worth the extra outlay IMO.

Ratio 1:2 is where I would start. I would definately use belts on Z axis even if you don't use a ratio, it's more flexable and helps eliminate resonance.

Edit: If you run Mach3 then here's what I do regards tuning and belt drive.?
I setup different tuning profiles for different types of work, IE 3D work I tune the motors for lower velocity but higher Accelleration then save it has 3D which I then load when doing that kind of job.
I basicly have 8 profiles.!! 4 set for 1:2 ratio 4 identical 1:1 Ratios. These tuning profiles are basicly Aluminium, Wood, 3D and 1 imperial setp same has aluminium for when using imperial G-code.
Initially it takes a bit of time setting up but wounce done thats it and it's very quick switching from one type of work to another with optimum tuning setup.
