General Mach Discussion / Re: New to CNC and built my own CNC but now come the questions

« on: April 07, 2019, 02:34:04 AM »

 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
Part No.:                         34HS1456
Frame Size:                     NEMA34
Phase:                 2 Phase
Step Angle:                    1.8 degree
Current:                         5.6A
Rated Voltage:         3.1V
Resistance:                   0.55Ohm/phase
Inductance:                   5.5mH/phase
Holding torque:           1232oz-in     (8.4N.m)
Detent torque:                  12.5N.cm
Rotor inertia:                2900g.cm²
Number of wire leads:   4 (Red A+ ,Green A- ,Yellow B+ ,Blue B-)
Weight:                                 3.8 kg
Length:                                116mm
Matched drive:DM860A
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!

Tim

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

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

 Hello Craig, all I can say is wow, thanks!! Well reading the forum this morning for me I saw that many CNC users use the  Ethernet SmoothStepper and so with you using it think it would be a great fit for me. I found one that will can be delivered in just a few days if order tonight. Their Warp9td website is full of helps which is awesome to me but only thing holding me back is the BOB's and you covered that with C10's. For just using 3 axis XYZ and limit switches how many C10's would I need. I found the C10's on amazon and ebay so was going to order same time as Ethernet SmoothStepper.


Thanks mucho, Tim

Thanks Reuelt for your help and suggestion on ethernet interface. I am presently looking at it online.

Thanks for the response Joeaverage! Well I have read many helpful responses and yes we were one those who has given lots of help. I just have a 3 AXIS system, what is your recommendation for good interface switch. I am ready to trash this horrible USB interface I currently own. I need to stay with USB or could use ethernet. I looked last night online for a substitute but obviously I need someone like you to send me in right direction, need good documentation for newbie.  Thanks so much for your quick response. Tim

Thanks Lumber60, you have giving me hope hehe. I just removed all the wiring from the interface board to the stepper drivers and going to start over. The vague documents given with Interface shows that XYZ are 0 for Step Pin# and Dir Pin# . This seems odd but again I know little about MACH# config. Do you know if you had different values other than 0. Anyway thanks again for encouragement. Tim

Hello everyone, I just have to say sorry for any stupid questions I have but am not be able to move forward with my project without some answers from experienced knowledgeable folks. I also must add an apology but from reading through many of your post on your forum that many do not like the China made components which I am guilty of purchasing. My project started from buying some persons DIY plans but found out after building the structure of the CNC that none the components still existed and had to shop for like kind updated parts. The plans always called for a MACH3 USB (only) interface board. The MACH3 support page on installation and setup which I have read twice seems to only talk about setup for parallel port interface breakout boards. This is where my understanding is very limited and questions are about connecting the stepper drivers and limit/home switches.
 My desktop unit I am using that is 2.5 GHZ with WIN10 home.
 Interface board is named BL-UsbMach V2.1 5 Axis.
 3ea DM860A Microstep stepper drivers.
 3ea power supplies.
 3ea Nema 34 Bi-polar motors.
 I have loaded the MACH3 software with no hickups and did the re-boot after intall. After spending a hr trying to find the Driver Test .exe Only to finally read that its not avaiable for ethernet or USB connections.
 The interface board developers send you config docs but many things do not make logical sense like Pin in / Out. They use same pin# for XYZ. I can only get X motor to operate and this is probably my issue but not sure.
 The Limit / Home switches have been wired with 2 switches on each axis of XYZ hooked in series with shielded grounded wires. I again was thinking each set needed to be hooked up on interface board each having there own pin# but after reading seems there is a better way of hooking to interface board.
 I have no need or desire to hookup my spindle motor since it came with separate power and speed control. I just trying to connect XYZ / Limit/Home switches and config the MACH3 software.

Any help or suggestions are greatly appreciated. Will add the 2 PDFs that came with interface board, I did not use there MACH3 software though but have downloaded the demo version from ArtSoft website.
