AXBB-E Ethernet CNC Controller #5 Limit Switches!

Showing the idea of connecting limit switches to the AXBB-E CNC Motion Controller. We can use mechanical switches, proximity switches and other sensors suitable to be limit switches. AXBB-E works both with NC / NO contacts and NPN/PNP type sensors. Some basic informations. I'll make a more practical as well where I'll show how I set up all limit switches on a 3-axis CNC machine including 6 mechanical limit switche (2 of them for each axis).
Here is the controller seen in video:

These PNP Nc switches I think go from 6 - 36V. Is the 24v a matter of your choice?

[@GBWM_CNC]

You're right! I used 24VDC because this was the power supply I was going to use in my machine. Sorry that I didn't mention that but your comment will be helpful for others! :)

Fajnie czytelnie przedstawione😀👍

[@GBWM_CNC]

Bardzo mnie to cieszy 😁😁

[@rusticagenerica]

Superb choice of music !

[@GBWM_CNC]

Glad you like it!

[@TrPrecisionMachining]

buen video..gracias por tu tiempo GBWM

[@GBWM_CNC]

Gracias Michel! :)

[@estebanalgar4704]

Good video but it’s very difficult to follow the typed instructions on the screen because appears few time. It would be better maintenance them more time in the screen. Thanks!!!

[@GBWM_CNC]

I'll try to improve in my next videos :) thanks!

This time some basics about limit switches with the AXBB-E controller. Next week we will probably take a look at RIGID TAPPING with my DIY CNC mill made out of an old manual milling machine. If you have any question or tips - drop it here in the comment section :)
Thanks for watching!

Could you do a video on wiring an e-stop (three wire) to the controller

[@GBWM_CNC]

@@leonsplaylife Are there 3-wire e-stops? I didn't have any experienc with them.

[@GBWM_CNC]

@@leonsplaylife (yet)

[@leonsplaylife]

@@GBWM_CNC Yes they are three wire?

[@GBWM_CNC]

@@leonsplaylife I'm not sure if I understand

[@schum22]

Hello, good video.
Have you tried to used 2 (or more) proximity sensors on the same input? Is it possible?

[@GBWM_CNC]

Hello! I didn't try that. Do you want to wire them in series or parallel? I think with NO-type sensors there should be no problem with a parallel connection. On the other side in order to connect sensors in series - you could use 3 wire sensors and just connect the power inputs to the first one and the second one would have the output of the first one connected to one of the unconnected power inputs (the second one would be connected directly to the power input) and so on. That's how I imagine that although I didn't test that. Maybe I will have a possiblity to test such setup in the future.

[@automatykaprogramowanie7172]

Witam, mam pytanko, czy danym sterownikiem da się uruchamiać program frezujący z czujnika?

[@GBWM_CNC]

Witam. Chodzi by potraktować sygnał z czujnika jako sygnał start? Jeżeli tak to bez problemu. Mam w swojej frezarce zwykły przycisk, którym można rozpocząć program. Można go bez problemu zastąpić czujnikiem.

Muy ilustrativo y fácil de comprender gracias por su aporte. Tengo una máquina hecha con el mismo controlador donde solo utilizo finales de carrera mecánicos, con señal NC. Quisiera preguntarle ya que por sus publicaciones veo que usted tiene amplios conocimientos técnicos., como podría evitar al energizar los motores paso a paso de los ejes un golpe o ruido fuerte más pronunciados después de varios días sin usar la máquina. Utilizo una fuente de 48 vdc hecha con un transformador toroidal, los motores tienen encoder. Es el único problema después funciona todo bien. Un saludo desde España Wiilly.

[@GBWM_CNC]

¡Me alegro de que te gusten mis vídeos! Creo que es normal que los motores paso a paso emitan un sonido de golpe cuando están encendidos. Mis motores lo hacen todo el tiempo (si entendí lo que quieres decir).

[@willyrodriguez867]

@@GBWM_CNC si solo emiten ruido al conectar la corriente que los pone enclavados después no. Gracias por responder.

[@marcinranoszek64]

Ile kosztował ten sterownik? Fajne odcinki tak trzymaj 💪

[@GBWM_CNC]

Około 1000zł. Dzięki wielkie :)

Do you know how this axbb is different or better than the uc300 or uc400 model

[@GBWM_CNC]

You'd have to take look at I/O. I think UC300 / 400 have other count of inputs / ouputs. Also those need breakout boards for each port I think (similar as the port 3 in AXBB-E). But I have no experience with those yet.
