After hrs of trying to find how to set up mach 3 finally found this video which worked cheers mate
I'm glad it helped😁
Very good u r best mach3 teacher ,,👍
thank you! :)
Great job sir thanks ❤❤
you're welcome!
Thanks for the helpful video but You are incorrect about connecting the PNP proximity sensor to the Mach 3 usb controller. It's possible and it works.
Are you sure you can do it with this controller? I've tried and there was no option to make it work. The manual states it needs to be NPN. How did you make it work as PNP?

Will hook up in series work with my always close with two wire set up? No luck thus far.
Thanks good video!!
I'm glad you like it! :)
is the wiring the same as the PNP type?@@GBWM_CNC
спасибо за проделанную работу .
Super erklärt! Danke 👍🏼
Gern geschehen! :)
Compliment from Palermo Francesco
thank you! :)
For 3 wire NPN: brown wire (+)24v psu, blue wire (-) psu, black wire to usb board IN2, IN3 ect
usb board In1 normally use for emergency switch
usb board: +24v psu to 24+ board , (-) psu psu to DCM board
Is there any mistake on the video? It seems I've show exactly the same as your description at 4:18. If there is anything wrong - let me know
@@GBWM_CNC
I did not watch the whole video, so I thought he was testing only 2 wire sensors. My bad. My setup is using 3 wires NPN sensor.
This video with same BOB ua-cam.com/video/SRu599Noeww/v-deo.html. Uses a PNP NO sensor.
The author (CBWM) of this video uses NPN NC sensor.
buen video..gracias por tu tiempo
Muchos gracias!
Tengo una placa mach 3 USB MK4-IV, no pude configurar los sensores inductivos PNP NC, creo que en ésto tienes razón. Ahora tendré que comprar sensores inductivos NPN. 😢
A veces un hombre tiene que hacer lo que tiene que hacer :(
Hi,
I would like to clarify this..!!!
Suppose I have downloaded a fresh copy of Mach3 from the Official website and configuring for a CNC Router Mill.
Starting Over with a fresh Software Copy from official site always gives that warm and fuzzy Feel....Na ? LOL
Any recommended parameters other than these?
1) setting up the Steps per Unit is easily done by inbuilt calibration option
2) Setting Velocity and speed can be fine tuned by trying multiple combination of values and test runs until we feel comfortable
3) The Configuration of Soft Limits and Limits Switches and Homing switches are optional as We can live without them.
Do You recommend any additional parameters to be set up for the smooth operation of A CNC Router ?
I have seen Many additional parameters tweaking by People Such as-
Constant Velocity/Exact Stop
Debounce
Frequency Of Communication
Look Ahead settings
Are these settings that Important?
Do You have any inputs to give on them?
I want to perform it like a Smooth CNC Router which Can Carve some smooth Wooden Legs and Figures..!
I am going with the most Common standard and Conventional Configuration which is -
4 feet X travel and 8 Feet Y travel and May be 1 feet in Z travel ,Just like the Standard Convention.!
I am waiting for the beep sound at the end of the video :D
Sir,
How much would you suggest the RNR USB Card for a Woodworker CNC Router?
Have you run any Longer carving Projects using the RnR USB card?
Have you faced any unexpected interruptions or missed steps?
So many videos say that It shouldn't be trusted for longer projects?
Yes, these RNR boards tend to have electrical noise problems sometimes if you don't do everything perfect. I had to isolate the power supply of my laptop to make it work (even emi filters and shielded cables didn't help me). Usually there were no problems with jobs at about 15-30min of work. I didn't do longer ones. Usually if there was a problem the machine missed some steps and stopped (the controller somehow saw that something goes wrong). If you want to be sure for your connection - look for an ethernet port cnc controller like axbb-e or mesa (if you want linuxcnc).
In India , dont have access to such Ethernet Controllers. Or they would be insanely expensive if I source from abroad due to the Taxation and import laws here. China is almost in red Category. So No Aliexpress either..! @@GBWM_CNC
How do I get my PC to even see the Mach 3 board made my bitsensor like yours!
So far it ignores that it is even there!
Connecting it to IN1 in your hand drawing diagram?
I'm pretty sure IN1 is the main Emergency Stop switch?
IN2 and IN3 is for limit/home switches and IN4 is for probe.
Actually it doesn't matter which input you choose. You can setup all the inputs as you wish in MACH3 :) so the for example the probe can be connected to in1, in2, in3 or in4 as long as you set it in the software.
@@GBWM_CNC You can switch the 4 output controls on and off ,but you can't reassign the IN(1-4) pins, they are set functions on the main board, all you can do is opt to not use them!
@@DogSerious I checked a manual available in the internet for this board to make sure and it says these can be configured in mach3
@@GBWM_CNC You're right, you can reassign it, but only to pins10-13 and 15. But I think the computer is showing port pins rather than the expanded board pins.
@@DogSerious From what I remember - the RNR plugin makes MACH3 show board pin numbers instead of port pins as this board doesn't use parallel port at all. But I don't want to misslead anyone now - I'm not able to check it as I don't have now access to this controller.
smc4-4-16a16b paneli kullanıyorum limit switch bağlamak istiyorum yardımcı olman mümkün mü acaba ?
Hi. I have just purchased this board and will be using a 3d touch probe. The probe has 3 wires, 24v+, 24v- and a signal wire to the pin 4 (I think). The way I see it is that the probe is NO and the signal wire when activated will send a 24v+ signal to pin 4 (active low NOT ticked) activating the board. Would I be right in this understanding? Much appreciated.
Had same problem. Fix using cheap Arduino Relay Module. Calibrate probe after installing relay.
The Asian side is mostly NPN type. The proximity sensor feels short in sensing. I'm curious about the acceleration and deceleration peton.
I've just used 2 type CNC controllers - this one and a CNC BOB based on LPT port - actually both seem to use NPN as you state. Btw what do you mean by acceleration and deceleration peton?
Does this card support the index signal for threading?
from what I know - this board doesn't support threading
Excuse me and to connect the 6 sensors, how would it be?
what kind of sensors do you have? With 2 wire sensors this will be probably not possible to do. With NPN you should be able to connect the output of the first one with the (-) input of the second one and so on wiring them in series. This should work I think but I didn't test it by myself. But NPN - only in NC configuration
Kardeşim merhaba, kanalını beğenerek izliyorum. Sayende Endüktif sensörü limit switch olarak kullanabildim, benim şöyle bir sorum olacak kendi çapımda ufak bi makina yapmaya çalışıyorum router mantığıyla. Misal motorları 0(home ) pozisyonuna gönderdikten sonra motor sürekli artı yönde dönecek fakat limit switch tetiklense bile görmeyecek bir mach3 ayarı varmı?
Ne demek istediğini anlayamıyorum. Tercüman kullanıyorum ama mükemmel çalışmıyor. ingilizce kullanabiliyormusun arkadaşım?
2 sensörden hangisini indeks için kullanayım? İki kablolu olanmi(2 wire) yoksa 3 kablolumu(no npn)
Ikiside olurmuş 🤣yinede adamsın cuma saçma soru için ozur dilerim, bu seylerden hic neredeyse hic anlamama ragmen yapmaya calisiyorum beni yalnız bırakma işime yaryorsun. Şu makineye yapmam lazım sizin bilgileriniz çok işime yarıyor adamsınızzzz wear manss 🤣
NPN kullandım ve iyi çalıştım :)
Very good, I have a problem that I have found in Mach 3, I have the STB4100 controller with the TB6600 drivers and 4 nema 23 motors, the problem is that I get a warning (G100) when trying to set the soft limit, it drives me crazy and I don't know what to do anymore, it's been 2 months now and I haven't been able to solve it, I would really appreciate it if you could help me. If you need any more information to help me, do not hesitate to ask. Thank you for your time, greetings.
I've got sadly no experience with that controller nor the warning so I can't help. I'm sorryy
Bunu indeks sensör olarak kullanırsak diş açmak için yeterli olurmu ?
Büyük bir atalet makineniz varsa - muhtemelen evet. Benim için işe yaramadı (cnc torna tezgahım küçük) ve bir enkoder kullanmak ve diğer CNC sistemine (LinuxCNC) geçmek zorunda kaldım.
Cevapladigin için gerçekten teşekkür ederim cuma adamsın. :)
Enkoderli step motoru spinle olarak küçük bir cnc de kullansak diş açmak için harici bir bağlantıya yinede gerek olurmu? İndeks sensör vb.
@@emreucar6866 Mil sürücüsü olarak step motor kullanma konusunda deneyimim yok, bu yüzden size bu konuda yardımcı olamam. Standart bir AC Motor kullandım ve iş miline bir kodlayıcı monte ettim. linuxcnc'de çok iyi çalıştı. 😁
@@GBWM_CNC I really liked your video and it will help me. I wanted to ask you. does this red usb card work with linuxcnc?
Mam problem z podłączeniem kilku czujników NPN NC (ten sam model co na filmiku, 3 żyły). Czy jest możliwość podłączenia kilku czujników do wspólnego gniazda np. IN1 ? Jeżeli istnieje taka możliwość proszę o schemat, bo próbowałem już chyba na wszystkie możliwe sposoby, stosowałem diody i nic. Podłączenie dwóch czujników do wspólnego gniazda sprawia, że pojedynczo czujniki nie działają ( jeden zasila drugi?) natomiast kiedy zbliżę do metalu oba na raz to czujniki działają.
chodzi o podłączenie szeregowe czujników, tak?
@@GBWM_CNC Dokładnie tak
@@KanoB Szczerze nie miałem okazji testować takiego rodzaju połączenia. Na google jak wpiszesz "npn sensors in series" jest podstrona rockwellautomation (nie jestem w stanie podlinkować tutaj) gdzie jest pdf pokazujący takie połączenie aczkolwiek tak jak mówię nie testowałem w praktyce jak się to zachowa z tą płytką. "+" podłączony na stałe do obu czujników, "-" podłączony na stałe do pierwszego czujnika i potem wyjście z pierwszego będzie podłączone z "-" zasilania kolejnego a wyjście z kolejnego do płytki sterującej. Na logikę powinno działać w taki sposób.
@@GBWM_CNC Dziekuje, postaram się jeszcze dzisiaj dac znać czy to rozwiązanie działa :)
@@KanoB okej 😎
Problem in output when i command m3 all output on in series any soluton?
Could you explain a bit what you mean?
@GBWM_CNC i mean i have rnr usb board all input work fine and all output problem my 1 output for spendle and output 2 for flood when i comand m3 for spendle my all output turn on together
Means spendle and flood turn on together
@@naeemansar3524 did you try disconnecting all the devices and if the problem still occours
@@GBWM_CNC yes i change port and pin also but problem same
esses sensores não são próprios para esse efeito, tens que usar sensores (switche) de contato fisico.
Algumas pessoas usam isso com sucesso embora
how precise are them?
Sadly I can't answer at this moment but soon I'll probably use similar ones for my new build so maybe the answer will be there :)
Bro how I collect the database and save in computer
What kind of database?
@@GBWM_CNC sir I am heavy equipment inspector we are using prximity warning alarm system now my boss need monthly data of PWAS
How I take the data From the device to my computer please make video by it
@@mindchanged6548 I'm not able to help you out here my friend.
Technical instructional videos need verbal explanation otherwise they are a complete waste of time for the person who made the video and everyone who attempts to watch it. Seriously, how hard is it to just explain what's going on while you are shooting the video? If you are afraid to have your voice heard then why are you recording and publishing videos.
It's quite hard actually ;) anyway I think there is everything what is needed on the text on the screen.
