You can still get ULN2003's in DIP packages
so for three axis only one chip (perhaps in 
a socket) on a bit of perfboard would do.
 

So,when bought the machine i started with the idea of keeping the machine as it was, but after a week  of figuring out how the old system work, it let me do only one job then the motor of the y axis broke and leaved me. So now i was thinking a retrokit to mount on my machine because this  have to work hard and last. So idk i can change all the brain and use linuxcnc and leave 3 motors and buy another one new and with time and money i can change all of them . Or i can buy new motors and i don't touch it ever again(only for maintenance ). 
Btw guys do you have  a nice shop were to buy servo motors like the Delta B2 (ship in europe) i saw the motors on Namicam and Motion Control products, seem's good placees idk about the price but seem good pricing . And i need an advice leadshine if it's a good product for professional work . Because they are more cheap than Delta and i found them at really good price.
Thank's for your answers.

 

Yes, you are right. Didnt thought about darlingtons, but yes, they will be fast enough for this configuration.

So I will have to build a small board in between.

After fooling around for a while, I decided to retain the positive-Z-up configuration. It's basically what modern CNC machines expect, I gather. Also, EasyProbe doesn't work in the positive-Z-down configuration.

I would suggest using something like a ULN2003 as a level shifter

Hehe.
I know some people using cheap chinese probes (round about 60 Euro) with good accuracy. Will try one by myself for the next machine.

So. It doesnt have to be that complex

In fact I will update easyprobe because I will have an ER32 spindle at the machine. So I will add some stuff for users who do not have ATC.
