Connecting Stepper Motors to CNC Breakout Board BOB Parrarel Port Wiring + MACH 3 Setup

[@ferrychoey]

Thanks for the content, my stepper motor is already moving, from some references finally bob and tb6600 work.

[@GBWM_CNC]

Great!

Good job....and thanks for your videos👍

glad you like it!

obrigado! :)

[@khalilautomations659]

Nice video sir

[@mikefrom100]

Thanks for the content, I'm learning a lot, could you clear me a doubt regarding the 36v power supply output for the drivers, it only works with 36v? I'm looking for a similar board that has 12v and 36v but I don't think so, I'm from Brazil and the site that appears on the board doesn't send it here, what do you recommend me to use? Thank you and I love your channel!

[@GBWM_CNC]

On stepper motors drivers there are usually the voltages written. Usually it is about let's say 12V to 52V but it really depends on the driver how much voltage it accepts. If you use voltage written on the driver you should be fine. For example one of these I used here was 9-42V rated. Also the higher the voltage the more rotation speed you can get.

[@tolgaamedov1922]

Hi, can you please explain why the breakout boards needs to be connected with the USB too since it requires 24V supply?

[@GBWM_CNC]

It needs 5v supply from usb to work if I remember correctly

[@tolgaamedov1922]

@@GBWM_CNC I tried without connecting it and it works, but my machine is not ready yet, just the electronics. I have no idea what can happen when it actually works, maybe missed steps? Will see, thanks for the answers man, you are very helpful!

[@GBWM_CNC]

@@tolgaamedov1922 oh, yeah. Now i remember. I fargot once to connect it and the machine was behaving crazy. It was missing steps and even didnt want to work. After connecting the usb it worked great

[@umargul5644]

Great

Driver dobiera się do mocy silnika?? Widzę tam inny zakres Amperów. Masz może wiedzę o doborze Silnika krokowego[closed loop] w stosunku do wagi, którą dźwiga? Potrzebuję zrobić ramę XZ. Na osi Z będzie chwytak do detali max.2kg. Myślę, żeby oś Z zrobić na wózku i listwie uzębionej na profilu alu. Czyli 2kg detal + chwytak + konstrukcja, może z 6-8kg.

[@GBWM_CNC]

Driver dobiera się do prądu znamionowego silnika oraz napięcia jakim będzie zasilany. A co do doboru silnika krokowego to zależy jaki jest sposób zamiany momentu obrotowego na siłę liniową np. jak jest śruba kulowa to inaczej będzie zależnie od skoku śruby. Większy skok - szybszy ruch, mniejszy skok - więcej siły. Z listwami zębatymi nie miałem dużo do czynienia ale na pewno będą wzory jakieś. 6-8 kg to niedużo ogólnie.

[@chandrasenveralkar9140]

I have the same board but not getting connected to my computer? Please let me know. Which driver to be install for this card

[@GBWM_CNC]

There is a driver in the MACH3 folder to install if I remember well. Maybe that might help. Hard to help remotely.

[@Spaceman972]

Hello. I have the same breakout board and connected the x axis the way you did to test. I setup Mach3 the same was as well, but I get an "External E Stop Requested" error and cant figure out why

[@GBWM_CNC]

Hmm, I had a similar issue. I think you have either to untick somewhere in pin settings the e-stop or attach an e-stop to the machine and make it work or make it work the opposite way. Something like that but I don't remember exactly what worked for me.

[@Spaceman972]

@GBWM_CNC Thank you for replying. I figured it out. For it to work properly, the parallel port, 5v power, AND USB has to be plugged into the board. I thought it was parallel port or the USB, but mine requires both.

[@GBWM_CNC]

@@Spaceman972 Yes, it requires both.

[@yourdad8582]

Which pin does the Pulse+ & Dir + from drive go into this pin? There are many wrong diagrams regarding this board on the internet. Please reply

[@GBWM_CNC]

Could you explain? You mean from CNC controller to which pins in the driver? If so - it depends on the driver you have but usually those are described. If you mean the CNC controller then you can set it up as you want in your software.

[@PulseGear26]

does this kind of mach3 board with lpt should run on windos 32bit? thanks

[@GBWM_CNC]

Yes, or linux cnc works too

[@PulseGear26]

@@GBWM_CNC thank you ✌🏻

[@PulseGear26]

@@GBWM_CNC do you have video about index pulse mach3 lathe for threading

[@GBWM_CNC]

​@@PulseGear26 nope, it didn't work for me. My lathe had probably too low intertia for 1pulse per rotation threading. I went to LinuxCNC and didn't regret

[@PulseGear26]

@@GBWM_CNC alright then i'll go with linux

[@mikhailmalamud9867]

I have the same breakout board. And it works but interestingly when I use multimeter to test continuity between pin on the breakout board and the pin on the parallel port, there is no continuity. Do you know why that might be?

[@GBWM_CNC]

You mean between a pin lets say pin for the x axis step signal and the corespoding pin on the parallel port input port on the board?

[@Saladdwork99]

I buy this mach3 board and connect to my window 7 64bit processor computer but nothing happened is this board work on 32bit processor

[@GBWM_CNC]

yes, works on my 32 bit procesor laptop

[@chrisw8357]

Umm, please use the convention, Red for +, black for -. It might cause smoke if someone does not catch that your colors are reversed. : )

[@GBWM_CNC]

At this control box i messed up some colors because i didnt have enough wires at home 😅. But I was teached at school to use blue /red for GND and black for +24V when it comes to control circuits (low voltage), light blue for neutreal and brown, black, gray for L1, L2 and L3. And yellow-green for PE.

[@mariuspetcu7482]

​@@GBWM_CNC I think You want to say - Red (+ )and Black (-) some times Blue for DC power

[@GBWM_CNC]

@@mariuspetcu7482 Actually you're both right. I was teached at school probably the wrong way (or they didn't have money for right color wires and didn't tell us those were not right) and I never looked up if they teach us it right. I did some research just now, and I'm suprised. All the time my thinking was wrong. Luckily I don't work anywhere as electrician so nobody will get hurt :) Thank you for correction.

[@naeemansar3524]

Which laptop and window u r using for parallel port

[@GBWM_CNC]

it's a IBM T43 if I remember correctly. Parallel works fine with windows XP (with windows 7 it had some issues). But I recommend using linuxCNC with parallel port - works best for me

[@r.g.lakshansadaruwan3193]

Does the rnr motion card support linuxcnc?

[@GBWM_CNC]

from what I know - nope. But this one works fine with linuxcnc

[@lucsem82]

good evening I bought a set with stepper motors with drivers all bought on amazon and it's called rattmmotor after the wiring and configuration it doesn't work for me and I don't know why could you help me please?😢😢😢

[@GBWM_CNC]

Hello. Sadly I didn't have any experience with such set 😔

[@DeepakSharma-gm8wr]

Will work without Mach 3 license

[@GBWM_CNC]

Check out on artsoft page. There are the limitations of demo version without license. When you don't have a license you're limitated to a certain number of GCode lines and some other things.

[@randyorton4435]

can we connect parallel port to USB cable for mach3

[@GBWM_CNC]

I've heard there are parallel port to USB adapters (with some electronics in there) but I've not used them. But this card won't work directly with only USB (it's for powering the card)

[@Saladdwork99]

[@desparadosolo3809]

my laptop doesn't have a parallel port any suggestions?

[@GBWM_CNC]

There are USB or Ethernet cnc boards. Im using on one of my machines a USB cnc board and works fine.

[@mightyweapon]

hey mate, do you know where to get the dll file for this board, i wasnt sent and having trouble trying to fins, i have dll for previous rnr motion board, was sent this one which i didnt order, ill use. cheers

[@GBWM_CNC]

Hi! This board doesnt need any dll file to work.it should work straight away :D

[@mightyweapon]

@@GBWM_CNC thanks for the reply, so i ordred a rnr as have used before and was sent the wrong board, so does this board only work with parallel port and usb for power?

[@GBWM_CNC]

@@mightyweapon exactly. This board (if it is the same one) works only on parallel port and usb is only as a 5V power supply. there is no USB communication as in the rnr board
