RPM Sensor for CNC
Рет қаралды 3,937
2 жыл бұрынIn this video, I'll sow you how I added an RPM sensor to a manually controlled CNC spindle. You can also use this on auto controlled spindles as a visual double check.

I was scouring Amazon for this just the other day wondering where you got it! Lol I'll have to pull an Arduino out of my spare parts box and make one thanks for posting this!

Nicely done. Could you show your Speed controller setup. Thank you for putting this video up.

i think your designs are really awesome! can you share links or files (fusion) of the wooden replacements you've made?

Great video, thank you for your work! Question: Does the length of the black painted rectangle count? Has it to be the half of the scope?

Not really, as long as it's once per rotation and is big enough for the sensor to pick up

Hello, This is nice job and I'm just starting the integration on my machine. I'm trying to recreate all design for sensors ans so on and I would like to know what is max distance between sensor and fan, Did you have a link if you already shared the design on Thingdiverse Thank you for you job.

Have you made any new updates to the cnc machine? Maybe an update video in the future? ✌️

I have just modified it to be 600mm x 300mm. Video is coming soon

@@Wallworkshop Nice upgrade Matt. I'm also in the process of upgrading my 3018. This will now be 3055 and everything from aluminum beams. I look forward to your video.

Might I ask how to add the extra arduino code? Does it go into the Grbl code? Also, have you thought about controlling the spindle speed with the likes of Candle via the board and psu? I believe you'd need to add a PWM but I have no idea on how to do it.

Hi, the Arduino code is loaded directly into the arduino as it is completely standalone from the main control board. I did look at controlling the spindle via the main board but i like the ability to adjust the speed very quickly to get the optimal cut etc. However I might get the main board to start and stop the spindle which is slightly easier to implement.

Hello Matt, can you please tell me what are the lowest RPM at which this motor can run?
@Wallworkshop 6 ай бұрын
It can run as low as 700rpm but I wouldn't want to cut at that rpm as it's a DC motor so the torque will be terrible

Can any Arduino work with this design or just a pro micro

Any should be fine, i only used the pro micro as I had one to hand

Hi, does anybody know the maximum frequency the sensor can operate at? Cheers in advance!
@Wallworkshop 4 ай бұрын
What do you men by frequency? Maximum RPM it could detect?
@Sophie333C 4 ай бұрын
@@Wallworkshop the maximum RPM will do, I just going to do it in a more accurate way, you can use the timer of the nano to get the frequency, from the frequency you can determined the RPM……yes so knowing the maximum RPM the sensor can sense would be helpful!
@Wallworkshop 4 ай бұрын
20000 rpm is only 330 pulses per second so I'd say it could read alot faster than 40000 rpm
