If you have found this video to be helpful, consider making a tip. Thanks.
Equipment that I use to make videos:
Canon EOS Rebel: amzn.to/2rJSeh0
Macro Lens: amzn.to/2qaSKmK
Microphone: amzn.to/2qO2RB4
3D Mouse to rotate/zoom/move the object (Must have for CAD!!!): amzn.to/2ruFnSn
The drafting pencil I use on these videos: amzn.to/2qioYg2
The cheap oscilloscope that I use (because it's cheap and will work all of the projects in these tutorials): amzn.to/2rSHnBa
A better oscilloscope and the one I would recommend: amzn.to/2qizK5M
The brand of multimeter that I use and the one I recommend: amzn.to/2qicUez

@cicothemajstor The annotation changes have been established. Thank you for your comment.
Thank you so much for this series of guides - it has helped me immensely to understand what is required to get CNC connected and working - Kev
@cicothemajstor Thanks... I will make an annotation on the video to reflect this best practice.
Thank you so much for your videos! You are a true talent! Great presenting, great explaining of information - fast explaining, full explaining, only usefull information, only right videos, - really really great job! Thank you a lot again, keep on doing your great work :)
Thre power suplay is NEVER conected to drivers as you did ! the right conection is that from power suplay every driver conected separatley , NOT DAISY CHAINING as you did !
explain more
actually yeah, that looks like a bad move...
I don't understand that annotation. What is the difference in connecting the way you did and what the annotation says? Both are parallel connections connecting the drivers from the same power supply output?
When all the drivers draw full current the first segments of wire carry all the load for all drivers..
When you connect each one to the power supply each segment carrys the current needed for the particular driver, that's why the way discribed in the annotation is better..
The CNC PC is outputting a pulse train square wave, is this correct? For use with a AC Servo motor does the pulse train get converted to ? PWM, or 0-10VDC ?

I'm probably overthinking this , but I was debating to use terminal blocks in order to do multiple connections . But I'm sure there's nothing wrong with using two jumpers in the same slot and jumping from one stepper driver to the other
My idea would just make for extra connections to fail
Yes, that should be fine if you want two motors to act from a single axis. Many CNC configurations lend to this since you may want to drive a heavy gantry using two motors instead of a single heavy motor.
Yeah... I'm not perfectly sure, but with using two drivers on one digital connection, you are sure to get synchronized movement. If you use the A axis, you can't really be sure to get the step pulses at the exact same time. Knowing microcontroller programming and processes, each signal is sent as a separate instruction and you never know how the manufacturer or developer of the software (control program) and firmware (the microcontroller code) coded the sending of the pulses. It's just better to be safe and use a single step and direction output. You will also free up the other axis for future uses. Don't forget that there may be mechanical solutions as well.
Excellent series. ty
Hi patrick what did you do with the enabled port on the drivers because on my kit I cant find the enable on my control board
since well im designing a totally different CNC machine were by i will be using two Z motor do you thing i can connect them parallel on the Z controller ? or do i need another controller but on control circuit i parallel the connection of coding wires
Hey Patrick. What is the diameter for de wires of the power supply and the motors ?
Please, could you add a video on how to connect USB cnc board from BuildYourCNC to small 2.5AMP motor driver. I think I saw it on your channel couple months ago - do not see it now (when I need it most). Thanks
Thanks!
what would you set dip for running rack thanks for sharing
Hello, could you put a video on how to connect the red emergency button please, your explanation is very good and I would like you to help me with this problem
I like how the breakout board has screws instead of some push on terminals . May I ask which one it is?
This is the parallel board that is the same as in the video but uses SMD components to make the board smaller:

thank you very much . And thanks for the tutorials , as there very informative.
. Others have no narration, and play some crappy music in the background , which drives me crazy .
Not a problem at all. Thanks for watching!
Thanks!
Sir can you tell me the best quality laser tube with specification
Is CAT5 cable good for the wiring? Other than power supply.
Awesome videos would this same settings work if I use bigger motors like Nema 42 ? is there a way to control a spindle on and off with the C10 board not spindle speed only power on and off I want to mount a regular hand router on my build but dont want the hazel of turning the router on and off by hand your help is greatly appreciated

@cicothemajstor keling driver distributor recommends connecting drivers in parallel as he showed in the video why do you say its wrong? thats not true...
How would you mirror A to Y for a double motor on the Y axis?
Sotm buy another motor driver and connect the input signals to the other's input signals.
I know that it is not that easy. The board has to somehow mirror the extra motor driver.
could you help with schematic, whit HY-DIV268N-5A...THANKS..
sir can 6.2 Amp stepper motor run with the DIP switch setting @ 4.5 Amp RMS and 6.0 Amp Peak current??????
yes
I followed all the steps and have no communication from mach 3 anything I missed?
Make sure to test the parallel port pins for a high and low on a direction pin.

Do I use the same driver if I have 2 motors to move the x axis?
No. Each stepper motor should have its own driver. If you need to have two motors on one axis, connect the controller step and direction pins for that axis to each of the two stepper motor drivers.
Patrick Hood-Daniel so from the 2 pins on the breakout board to driver , then I can jump step and direction from driver to driver to share the 2 pins on the breakout board to share the axis ? Then how do I get each motor to turn a different direction I'm using gear rack so 1 motor will need to rotate the opposite of the other is this something that is done through the mach software? I just got the same kit kl4030
I would run two wires from each pin rather than jumping from driver to driver. There will be less resistance on the wires that way.
To have the motors turn the opposite direction, just swap the A and B wiring from the stepper motor to the driver on the one you want to turn opposite.
Patrick Hood-Daniel sweet! Thanks for the quick reply your video has helped a lot I'm assuming this is why people test everything before it gets installed on the table
You're welcome
Hello and congratilation on the videos! great work explaining! still ineed some explaining on supply voltage for the servo motors, the power supply is delivering 36V and the motor are 4.5 volt aproxmately, so you are overvolting the motor having risk of burning it, is the motor controler regulating the voltage and if this is the case how do you configure it? could you please help me on that???
Also amp's are harder to control than volts, amps make a lot of heat on controler it's prefereable to use highet voltage to achive the same wattage? no?? still great work Patrick
and will be looking for the finished macine working video!
Hi:) That is only a voltage to rpm ratio for the spec sheet. The motor can handle 4 to 20 times the rated voltage that will be required from the power supply.
cybot63 4x4.5=18volts on the low end and 20x4.5=90volts on the high end.
Should be separate cable to each power supply to the motors - 1st 30sec and did not want to see any more - sorry
+Tom J Designs (Pro DIY) yes and no, if the cable has been long enof and with the use or the correct cable with cable shoes. no problem. but i agree with this setup its waiting for misfunctions
i needed teh motor connection of drivers but video ends there. sigh
Thank you very helpfull
Hey buddy - you connected your power in series parallel and that is not OK. Connect in parallel instead.
There is NO such thing as series parallel! It's either series or parallel, but NOT both together!
hi
i liked this machine very much.
i watched all your videos related to this machine, it`s very cool
now i`m really asking for your support to make my machine
i`m Walid from Egypt and we have one shop selling cnc parts( ram-e-shop)
kindly can you support me to chose what parts i need to get from this shop?
i will very pleased to have your replay
best regards
