Quest for a CNC stopped ! . . . - Philippines

I am working here in Saudi Arabia and got a deep interest on CNC's, have surfed a lot of sites and my quest stopped upon seeing the MM table which suite my requirements, presently on the Planning stage, plans are MM definitely! next would be selection, sourcing, and establishing budget for motors, drives and controllers and other accessories. I plan to start construction by January 2012 in the Philippines.
Cheers!

Thanks John#26, just started sourcing stepper motors here in the Middle East and South East Asia particularly in Singapore and Philippines.

Thanks Mike, 'first glance at the MM and the people around it is an inspiration for someone new to the world of CNC's like me. Cheers!

I try to grasp only the basic of these electrical/electronics . . .

Please advice on the integration and performance of the following:

Motor: UIM86-A stepper motor
Driver: UIM24004 stepper motor driver
Breakout Board: UIM2901-5A for Mach3

Thanks . . .

After reading and a tight budget, I'll start with the following drive system:

1.) NEMA 34/126mm Stepper Motor, 4 Wire, Bipolar, 5.4 Amp Rated Current, 5.8 mH Phase Inductance and 7.4 N-m Holding Torque
2.) Integrated Stepper Motor Controller, 10-40 Input Voltage, 4-8 Amp Output Current, 1-16th micro step resolution, Automatic Current Reduction, Dual full H-Bridge with PWM Constant Current Control
3.) Power Supply, 36 Volt, 10 Ampere, 220 VAC
4.) Mach 3 Breakout Board

I have received the Invoice and the lead time is two weeks.

Power Supply, 36 Volt

will be a very low voltage for those motors, get something like 60-70V for speed
also the " Integrated Stepper Motor Controller, 10-40 Input Voltage," will then be out of game because of low voltage rating.

If on budget contact Deitech (www.driver-motor.com) they are close to you, get some appropriate drives and 9801 or 9802 motors which some of us use, those are in 40-50V range so you can get cheap drives 4.2Amp and 50V

I am happily running my MotinKing 34HS9801 steppers with UIM 4A drivers at 36 volt....and have plenty of speed in reserve. The UIM's do 40v max, so 36 is a good safe voltage for them....just my 2c's worth

9801 are ok with 40-43V I run those with that voltage too, but the ones Nest chose are no good on that voltage.

I see you advertise the UIM a lot

p.s. Mistake... mine is 86HS9802 and its 2.4mH at 40V

It appears that Kobus is running the 34HS9801 with an inductance of 4.1, whereas the proposal here is for something like the 34HS2801 which is physically larger with a larger inductance. Several of us suspect this may become a problem; either smaller motors with lower inductance, or higher voltage drivers should be considered.

Please report back on your results, regardless of what you choose. http://www.mechmate.com/forums/showt...=stepper+motor

A tight budget has led me to this road
But reading from this forum and surfing a lot of other sites, I have read that new IC tech digitally driving analog circuitry can deliver maximum power even at high speeds.
@Kobus, I am somewhat relieved someone's running UIM's which supports the above.

34HS9801 in half-coil can be use with off the shelf 48Vac transformers & 75V rated capacitor which will eventually give 60~63V dc. I use it without problem since day 1. All you need to do is to find a motor driver that is safe to operate in that voltage range.
