Offline Controller SMC4-4-16A16B

[wisconsinjimmy]

Thought I would give this thing a go but when it arrived there are no instructions with it and what instructions I found were people pushing buttons but nothing absolutely nothing on how they made it work there is nothing about the drivers for the motors or if I even need drivers, I am lost
Thanks Jim
Merry Christmas all

Yup I saw that but it seems to be a bit confusing so I will print it out and then do the read, I am really new at this stuff that is why I asked for help. Well I printed out the manual and tried my best to get a screen shot of the first 3 pages but I gave up if you go to https://www.lollette.com/support/pdf...is-cnc1508.pdf on the first 3 pages are the hook up. On page one it shows the motor connections and I understand most of it except my motors are 23-205-DS8 3V-3A-1R and have 8 wires the plan shows 6 wires how do I tell which pair not to use. Thank you

Jimmy,

You are also going to need motor drivers.

Happy Holidays,

Hey Jeff
Thank you for the reply you set me on a better path, I am going to use what I bought from Hobby CNC as his controller has the drivers built into the main board no extra stuff to work with and go wrong.
Merry Christmas to you and yours
Jim

Here is my motor driver and on the high voltage side I would connect my four wires +12V DC power, where I get confused is which is the A a and B b I know that if I connect two wires together and the motor is stiff to turn I have the right pair. I am total loss on the signal side with PUL, DIR, ENA. I beleive that these will connect to the controllers pin out am I correct or way off. I also have 3 new 8 wire steeper motors but the eight wire seems to elude me I can tell you that A= Red, and a=Black Com=Yellow and Blue . B=Green and b= White Com=Orange and Brown but I do not believe that this type driver will accept 8 wire will appreciate all comments.

Jim,

Post a link or pdf of the stepper motor specs and wiring details.

Your driver will work with the eight wire stepper motor they should be connected "Bipolar Parallel".

https://hobbycnc.com/faq/ you will have to scroll down to the stepper motor FAQ,

For the diagram below, a parallel hookup would be as follows

Coil A+ : Connect both the red and Blue wires together
Coil A- : Connect both the yellow and black wires together

Coil B+ : Connect both the White and Brown wires together
Coil B- : Connect both the orange and green wires together



For the wiring, you wire exactly as shown in this picture from page 16 of the manual I linked.

Hey 109jb
Thank you for the diagram and I am now trying to get it wired, tomorrow I am going to cut a chunk of plywood that the drivers and also the controller can be fastened to.OK cut the plywood and mounted the drivers, followed the wiring diagram and now have the drivers connected to the controller, from here I will connect the motors to the drivers but I have one question what gauge wire should I use there are no markings on the motor leads. I used my mic and I got 1.57mm with the insulation on, also the wiring from the drivers to the controller I used 2.75mm..
Thank you

[jalessi]

Jimmy,

18 gauge stranded wire is prefered.

OK that puts another part of the puzzle together

Hey folks I am getting there little by little, I have my motors connected properly according to HobbyCNC but I have a question the board is set up for a parallel port 25 pin and my computer does not have a parallel port. I do have a UC100 when I turn on the power the motors sound like thy are running (main concern) but they are not (23-205-DS). I am going to use Mach3 for the program but as of this writing I do not have it set up

[jalessi]

The DB-25 connectors on the SMC-4 are Input and Output connections and never under any circumstance connected to the P.C. parallel port !

The SMC4-4-16A16B does not support Mach3 and is not needed since the SMC-4 is a all inclusive CNC controller.

My bad, I stopped working on the Offline controller and went back to the second project I was working on and for all reasons I think I am done except for setting up Macn3 boy am I in deep dodo for that
,°time to hit the fart sack it is now-17°F.

I hope I got these pictures proper now I am a bit confused, there appears to be two different ways to connect the power, the 7th pic shows 9-12V in, two grounds and a 5V out. I believe the 5 Volt out goes to the drivers and the sheet I have for hooking this up shows an external power supply which goes to picture 6. I also have an optocoupler but not sure how to connect it. There also is mention of a relay

Hey guy's I am going to hold off on this offline controller and put my energy into a Hobby Cnc Controller.
Thank you ever so much
Jim
