Lately spend too much time on choosing the BOB, motors and drives, which delayed my order for the ball screws and the rails. After all that talk, last night saw 2 interesting Galil listings on fleabay and something made me push the button and send best offer, thinking that if one accepts, will cancel the offer to the other.
Well, after i woke up this morning i found my self the happy future owner of 2 galil BOBs. i thought of excusing myself to one of them, then decided and payed them both. With the idea if one not working to use the other, or at least to see which one i like best. the other goes later for next machine or whatever.

So i bought the GALIL DMC-1880 PCI 8 axis Optima motion controller and the Galil DMC-2183 Ethernet/RS232 8-Axis Motion Controllers & 2 ICM-20105 Opto I/O .
Both seem to work with the Mach3 plugin / yes i checked before sending the offers/ .

I have some feeling that i made the right decision with these. What do you think?

Now i have to decide on the drives and motors. First of all now i can run steppers with encoder and servo motors directly closing the loop at the motion controller. Which in fact can lower the price of the build, implementing servos only for moving the gantry and steppers on the Z if i decide so.

No i am looking at a Galil AMP-19540 at ebay which coul drive directly 4 dc servos up to 500w each, costs only 100euro and connects directly to one of the BOBs i bought - the DMC-1880 . It seems this purchace can save me a lot of money on other drives and cheapen considerably the project, sourcing only the motors.

However i understand nothing of these type of servo and drives for me the description is like Chinese, i only see 500W :-) , here is from the description:
Galil's AMP-19540 is a 4-axis amplifier for driving brush or brushless motors up to 500 Watts. By interfacing directly to Galil's DMC-18x2, DMC-18x0, or DMC-18x6 controllers, it provides a cost-effective controller/drive solution for multi-axis applications. The AMP-19540 contains four transconductance, PWM amplifiers for driving brush or brushless motors. Each amplifier operates at 18V to 80V dc, up to 7 Amps continuous, 10 Amps peak. The AMP-19540 gain setting is easily configured with jumpers. The PWM switching frequency is 60 kHz.
The AMP-19520/40 is a brush/brushless trans-conductance PWM amplifier. The amplifier operates in torque mode and will output a motor current proportional to the command signal input.

Input Voltage: 18-80 VDC
Continuous Current: 7 amps
Peak Current 10 amps
Amplifier Gain 0.4, 0.7, or 1.0 A/V (jumper adjustable)
Switching Frequency 60 kHz (up to 175 kHz available--contact Galil)
Minimum Load Inductance 0.5 mH (low inductance option available)
Communtation Angle 120o (60o option available)

So, can some one help here please:

Can i find easily BLDC motors suitable for the drives, with hall sensors as far as i understood, new from ali express or from ebay? Are these drives any good, mean in 2014? And for my build?
