Got my £32 bargain Dell 780 the other day. Installed windows xp but weirdly it will connect via wlan to my other pc's but won't connect to internet? Probably a blessing in disguise tbf (no chance of viruses). Might try Windows7 at some point.

Looks like I'll be waiting until October for an AMAT25LV from Amadeal which is frustrating.
Gives me time to get Mach3 installed, the electronics box wired up & all tested before hand I guess.
In terms of steppers I might need something bigger than the Nema23 425oz/in I have for the x,y.
Using 5mm pitch ball screws I'm planning on setting it up with:
The drivers set at 1000 per revolution
The steps per unit set at 200
So If I'm right 5mm/1000 gives me 0.005mm resolution and 200 steps is 1mm (1 unit).
Should give me a reasonable rapid velocity.

I'm running my dying Sieg X2 on 2000/400 on 5mm pitch atm which Mach3 shows I could have a maximum velocity of around 2800mm/min ish.
I have to have the Gib so tight on that tiny table though, the motors start missing steps at 1400mm/min. Those settings give me 0.0025mm per step.

If I can get closer to 2000mm/min using the 1000/200 settings on the AMAT25 with a 0.005mm accuracy I'll be plenty happy enough :)
