Awesome vid! I've been working on nearly an identical tach for my g0704 mill and I'm now thinking I need to feed my sensor with 12v, time to do some testing with the multi meter.
You will not believe it, but my exact same tacho (in blue though) arrived in the mail today. My CNC build is slowly coming together... Will watch this video with interest.
i have the bl mach 3.3v and i can´t see the green light blinking? do you solve it until now i tried with all the pins number but nothing. Im using and arduino 5v sensor hall
Can you give some info on how to use data from tacho into mach3 for indexing used for threading. I have problem to use proximity sensor on mach3, it doesn't show up the correct number on mack3 S tacho. The sensor is working as index seen on diagnostic.
You had me in a panic about the sensor, I just ordered sensors for my CNC (metal triggered) and they are the flush type but after a quick test they still work so it must not always be true.
i did the identical setup.. the little chinese readout works perfect, but mach willl not take the signal..i tested all different voltages and pins. I really think 1 or more of my outputs are interfering , just got to figure out which one.
@@darkobul1 no , never solved.. I simply figured that mach was set up to read when running db 25 cable , and since i was running usb , it just never worked.. Ive spoken to others who also never solved it .I spent a solid month testing every possible soultion , had 2-3 different sensors , etc etc . I switched oveer to acorn , everything works fine

Similar setup should work fine for a Mill
Great information Sam. Thanks for sharing mate. Cheers, Aaron.
Thanks Aaron!

Yes they come in various colors, Just measure the tach signal output as long as its under 5v you can connect this directly to the BOB
Very useful. Can you tell me in which one AVI, GCM, 10V go the lines from the lathe tachometer.
Thanks
Dennis Anghelatos
I should be explained clearly in the videos
Thank You for this Video, Sam. What software do you use to layout your electrical diagrams (@6:06) ?
Tinycad
@@CNC4XR7 Thank You Sam!
Very nice lathe cnc. I have a mini lathe. How to you wiring tachometer with mach 3?
I have 2 videos on this please review both.
@@CNC4XR7 thanhk you very much.
Is a single pulse like this enough for pid spindle speed control? I really need closed loop spindle speed control.
It works well for CSS on the lathe But I cant say in that application.
Hello
With that type of sensor can CSS be performed?
Yes there is a video on css in the playlist

Can you help me with the link?

what are your voltages when sensor is active and not active?

Make sure you have Spindle speed Averaging selected.
Hi does it work with cnc usb (red board) i didn't find any plug diagram for this board thank's
I'm sorry I have no info on that board
I understand after watching your second video. Threading can be done when you have stable rpm. many thanks.
Yes, you are right
You had me in a panic about the sensor, I just ordered sensors for my CNC (metal triggered) and they are the flush type but after a quick test they still work so it must not always be true.
Guess not
what brand/model NPN sensor are you using?
should be a link in the video description

voltage to mach3 input needs to be 5v then drop to 2.5v once for every revolution.
Did you solve it? What was the problem? I have same issue.
