Thanks for the video, very informative. I have built a project that is using TMC2209 drivers. From what I've been told they run in stealthchop mode but I want them to run in spreadcycle mode. There is no UART communication and I could only find a vague reference to physical pins to change this. Do you have any experience with the 2209 and this shield?
EN is the exact same enable pin that is used for each of the stepper motor drivers i.e. pin 8 on the Arduino, with a multimeter you should be able to sense continuity between every connection marked EN. GND is the same really, its the same ground as every other place marked GND and hence the same ground as the Arduino itself. Hope that helps.
Thanks for the reply. I have inherited a CNC spindle machine and see that this pin is linked to ground. So, should this link be removed as it is in effect grounding the enable pin?
By the sounds of it the previous user has bypassed the enable function and made it so that the stepper motor drivers are permanently enabled (by pulling the level of the EN pin down to ground as explained in the video). The machine should still work with that setup, I can't see many issues coming up with that setup but just to be sure I would remove that connection. If you are using a commercial software to run the system that is made to work with Arduino and this shield then it will toggle the EN pin as necessary to run the motors as desired.
THANKS for taking the time to reply. That makes perfect sense as the motors are permanently energised. As suggested, I will remove the link and allow the software to control the enable state. 👍👍
Excelente muchas gracias por el valioso aporte, consulta, si quiera añadir otro motor nema pero no en X, Y, Z o A, sino desde los pines para habilitar un motor tangencial con cuchilla para cortes de vinilo etc, se podria, y como lo podria hacer si son tan amables por favor, muchos saludos y bendiciones.
This shield is used for stepper motors which work differently to other motors in that applying a current locks the motor in place rather than causing motion. Switching between locked states causes motion. I have another video on controlling stepper motors without motor drivers. The same code can pretty much be applied to the pins as necessary: ruclips.net/video/E_TI7ny26pI/видео.html A better video for this might be this though by Electronic Clinic: ruclips.net/video/TMK_fLgpESQ/видео.html For your specific question I'd suggest watching from about 15:00 in, but it might be worth watching the whole thing to increase your understanding of everything.
Hi. It is so important to understand what you are saying. But there is no need at all for any disturbing music. Please stop using that kind of disturbance. Thank you for your video. I tried to learn a lot. But I missed a lot I suspect. Robert
Thank you so much for doing this video and sharing the invaluable information. Amazon should put a link to it on their website!
Thank you for this video. It was very hard to find this info elsewhere.
Exactly why I made it. Glad it was useful

Your contribution enlighted my search...🥵👍
Which version/library of grbl are you using for the Mega?
Thanks. useful
Excellent !
Can you please tell me what the EN/GND pins are used for on the shield? (Near the reset button). THANKS.

thanks, is there a way to easily make one of the motors move just by connecting some of the pins together?

tnx!
Was the music added as a form of torture?
Are all Enable pins actually on #8 ?
With this specific setup with the Arduino Uno and the CNC V3 shield yes, also works for the Mega (assuming you plug the shield into the right place).
@@makeitquick9638 Interesting, thanks.
Would have been nicer without the music, but thanks!
Those who placed the A4988 as in the video, raise your hand...
Nice music but it's is too loud. I have to watch it with subtitle.

My apologies. I did not realise how loud it got at certain points and that it was so distracting, will keep this in mind.
