 Well my stomach now hurts from laughing, your opinions are highly regarded but your while very practical and helps, you do it with great candor. I will go checkout your leads to apps. I did the Vcarve and they free trial does give you the full power of there app but will not let you export anything you create. I will also download Fusion 360 and see what it will let me do.


Thanks Craig for speedy response. I guess again I don't understand what I should. I do own Mach3 software now but do I understand right that its only used as interface to my saw and can load Gcode into it. I am under the understanding I need a program to do my designs and then output to be loaded into Mach3. I thought Fusion 360 was free but looked at it and now have 30 day trail and then $500. Example I wanted to make small plaque stating my wife and I made our saw and then wanted to make a design for a bracket to connect a vacuum system. I saw that prices for doing truly extreme parts milling and watched so many YouTube video that are awesome. Those like commercial CNC machines are very expensive. I will download my trial version of Fusion 360.

Thanks Tim

Hi All, again want to say thanks for all the help you have given me, and Reuelt I love the way you think  :) on building a larger saw. MN300 I also agree in looking for away to keep dust away from my power supplies, THX. The learning curve as Craig said has just began and now asking what software would be a good start for me. I am just a hobbyist at this time and would like to make some simple signs and such. I have spent the last day looking and so much of the software is for true milling parts etc and extremely expensive. I just want to do some text and graphics (simple) stuff. Any suggestions again as always will be mucho appreciated.
Thanks Tim

 Howdy Craig, after re reading many times this bear of small brain understood, I always get mixed up when taking about Stepper motor which is used many times to say stepper drivers. Anyway I made the adjustments and the machine came to life. I am sure I will be doing some fine tuning but its works and I owe you a BIG Thanks!! attached is a picture of my SAW 1st test cut

Thanks sooooo much!


 Well I am obviously a bear of small brain, now that you put it that way makes very good sense :) ! I am heading out to do the settings in few minutes and will post a update, mucho thanks

Well Craig you have giving me a starting place and just think I thought I had a little grasp on this area and now realizing I need bunches of help. I will go in and check and I am sure I used inches.

Thanks again for coming through for me, Tim

I have motors connected directly to Ball screws. I have settings set sw 1 ON sw2 ON sw3 OFF, sw4 I left off and then I thought I needed to set sw 5 6 7 8 25600 not sure where I read something about that so OFF OFF OFF ON for SW5 thru 8.

 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
 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

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

 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!


 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!
