Hi Craig, well again thanks for all your time and info. I am presently looking at buying the Malaysia MB2, Its seems there bob is made to match the ethernet smoothstepper and I am looking at simplicity and functional. It looks thought might take a month to get it. If this all comes together I may be a constant throne in your side asking questions hehe. Ordered the ESS board and now looking if stuck buying from Malaysia just because of time.
Thank a million, Tim

Good choice for  buying the ESS.
In the "3 little pigs and the big bad wolf" fairy tale, Only one of them got it right from the beginning.

Yes indeed, they have made it specifically for the ESS and is a worthy choice.

My thing is electronics so I would rather have something simple and flexible ( and cheap)like a pair (or trio) of C10's and
make whatever specialist circuits I want.  I can understand that you might prefer the ready to go option.

I am surprised they don't have a distributor in the US...that might reduce the wait. In the meantime any cheap parallel port BoB
would probably be enough to get you going.

You are correct. I did purchase the UC100 from CNCDrive, and currently us the DB25 bob.
I also took your advice and purchased Mach4.  Works great

Hi Gerry, thanks for taking the time to send me info on updated MB3. I have already purchased the MB2 but you are right that the MB3 does have many nicer features. I told Craig about telling my wife who has been very involved in my building my CNC that it would cost just under a $1000 and now just broke $3500. I should have gone ahead and paid the extra 30 but really but felt I had already exceeded my limits. If after I get these components installed, setup and running for awhile I think I will sell the MB2 and replace with MB3.

Thanks again Gerry for your help! Tim

 Good Morning Craig, just wanted to say thanks again for your encouragement and input. You were so right about the folks on this forum being so very helpful. I did order the ESS SmoothStepper and its companion BOB. Hopefully get the components in a week and can finally enjoy the fruits of my wife's and my labor hehe. Hope you have a great weekend!

Hi,
maybe that extra $30 would be better spent on some nice flowers and chocolate treats for your missus.

You never know, you may have to soften her up for yet another (budget) blow! ;D

 I received my new SmoothStepper Ethernet and BOB yesterday. I just wanted to say thanks again to all that helped guide me to the right interface and BOB. Today I will begin to install and setup this baby!

 I 1st of all must say thanks for all the support I have received from forum members which has gotten me thus far. I finally got my wiring properly configured and now in need of Mach3 configuring for my motors. I used a Stepper Calculator posted and tried the numbers on the inch scale.
I am useing the following equipment and hardware.
Mach3 software (latest version)
Smoothstepper ESS
CNCroom MB3 BOB
 3ea DM860A Microstep stepper drivers. (Nema34 Stepper motor driver DM860A 7.8A 256micsteps 24~80VDC LONGS)
 3ea power supplies. (350W,48VDC Power Supply 7.3A for Nema23&34 Stepper motor&Driver CNC Router)
 3ea Nema 34 Bi-polar motors. (CNC NEMA34 Stepper Motor 1232OZ-IN 8.7NM,5.6A,118mm,4leads) Stepper motor
Technical Specifications

I am only using XYZ axis and drives are CNC SFU1605 Ball Screw SET. My power supply is set at 48V.
Any help with Moto tuning and Setup Motor outputs, not sure DIR LowActive or Step LowActive
Using the Mach3 MPG I am able to activate each motor nut they seem to chug and whine and miss a pause in rotation. I have verified the motor wiring to stepper driver is correct. I have my BOB wired using VCC connected to PUS+ and DIR+ then XS- connected to PUS- and -XD onnected to DIR- .
I have tried to list everything I have done, any help will be mucho appreciated.
Thanks Tim
