I know I thanked you before for putting this up, but I finally got around to hooking things up....so thank you again!!!! This was definitely a life saver when it came to getting it working!
Sweet! I've already got a sensor setup on the little lathe, but it only runs the tach readout on the DRO. I've been looking to run that input into the controller. This vid helps a lot!! I just need to find pin 10 and get the wiring connected. Thanks!!!! Mike
Thank you! You provided the missing information for my setup. The tip about having to set the spindle relays, even if not in use, made my RPM counter work. Thanks again!
Thank you! I was in trouble with the same thing. At first, when I watched this video, I didn't solve my trouble because I cannnot hearing English. But your comment helped me.
Good info! I'm working on a mill and spindle control/feedback is on the to do list. I am curious - how does this help with threading? Don't you need to know angular position so you can pickup the thread each pass? Are one magnet and rpm averaging accurate enough to pick up a thread? Seems like it would work better at higher rpm than low. Thanks for putting this all in one place. Very helpful!
I'm glad you found the video helpful. I think one magnet is ok if your machine has enough torque to make the threading pass without the spindle slowing down. I will confirm that once I have a threading tool setup on the lathe. Somehow, I think successful threading on Mach3 has more to do with maintaining RPM than detecting minor variations, but I will confirm.
Hello, first thank you for your detailed videos about using mach3 with a cnc lathe. Unfortunately I can not get this to work with a novusum v2 ethernet board. The index puls is working when I checked this in the diagnostic screen. I also have the spindle turned on in mach3 and. Only of speed averaging is turned on I get a value for a short while but within 10sec it dropes to zero again. Hopefully someone can shine some light on this because I am stuck on this one big time.
So with sensor hooked up like this video during threading the z feed rate will change depending on spindle speed?... so when threading when you engage part the rpm slows down a bit so z feed rate will slow down also?
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
hello, when threading, the cutter brings it to the start and waits for threading on the cycle G76. G code generated through the master. I can't find the reason, or maybe there was an error in the G code?
Franco, In the video you said something about using an ESS causing issues with spindle index with mach3. You never did explain what it was. Could you elaborate please? Thanks Es
It's been a while, but as I recall the ESS just reads the input pulse. The parallel port requires that you command the spindle before it will take a rpm reading. Otherwise, you won't see a rpm value.
Franco hello, I bought a sensor magnetic NPN and rode on my lathe, the problem I have now is that the LED index is not constant light 3 or 4 times after this 2 or 3 seconds off and back again, any idea what will be able to be? thanks
I've got the same issue. I think it's related to debouncing the signal. I get an accurate spindle speed on the DRO but my index is not consistant. Any ideas?
i have the sensor wired to the original estop location , which happens to be pin 1 and 10.. i get the green light in diagnostics, but no rpm reading in mach.
Make sure you have commanded the spindle to be turning. MDI M3/M4 or press the button that makes the spindle turn on. I struggled with that for hours before I figured it out...
@@FrancoCNC thanks.. Been working on it for 5 hrs.. I even have a digital tach hooked to the sensor to make sure im getting a reading ( i am . ) but , after going through every step under the sun , and having the index light on under 3 different pin selections , it will not read my rpm in mach.. What im thinking is its something stupid i overlooked.. (My output signal voltage ,the hall sensor proximity , an output signal thats interfering with the input signal , maybe the probe pin i have it on now doesnt read pulsed inputs etc etc ) ill stumble on the answer eventually , likely by accident
since then , i tried different voltages on the hall sensor.. I ran it from 4.2 up to 12 , to see if my signal pusle was too far above 5v to be read.. Turned out that was not a factor , it didnt solve it .Altough i do notice now , when i activate spindle , it says " too fast for pulley " every time.
@@airgunningyup if you see the index light flash on the diagnostic screen when you pass the magnet past the sensor, it is working - at the very least for slow RPM - but it's working. Sounds like you have some sort of software setting issue going on.
Hi. The Centroid system wants to use an actual encoder for spindle feedback. That is much more accurate but it requires a bit more work to mount it up.
Hi Franco, I have setup my mill with a hall sensor and get perfect reading on rpm with a short cable. But when in install the intended cable through the cable channels etc. i get somewhat funny readings. Say i run at 2000 r/min. i get about 2000 r/min most of the time but suddenly i get 250.000 or so. This suggest there is something going on when the cable length is different. Any suggestions ?
ERGOtek Mechanics Limited interesting. I've run my cables about 10 or 12 feet using 22awg SHIELDED wire. My sensor is running 5 volts. I don't get any interference from my motor wires or any other wires that are running beside of them. Check all the obvious things like loose connections. You may need to use shielded wire. You can also check the spindle denounce value. I hope this helps.
Hi. The larger the value, the longer the pulse must be active before Mach will consider it an actual pulse. I'd start with 40 micro seconds and see what happens. Slowly increase RPM and watch for errors.
Franco, what I want to understand is do you connect the sensor directly (without any resistor soldered to it) to the breakout board input? I'm asking because I've been told that a sensor can't be connect directly to an input.
+Mark Davis The hall effect sensor is very inexpensive and can be purchased via eBay. However, the housing it is mounted in was something I made. Check out these videos: th-cam.com/video/tT5-m5gAU-Q/w-d-xo.html th-cam.com/video/rxkaPBmdBYU/w-d-xo.html
@@crduli I bought and tested several boards, but the screws didn't break, now (Ethernet Smooth Stepper Motion Control Board) I am able to cut the screw using.
Hi Franco,thank's for your helpfull video. Do you think it can work with NC NPN hall sensor,i order a NC instead of a NO sensor,maybee by flipping low active in mach3.? Also,does anybody here have add a hall sensor on a cnc usb board ? Thank's

Thanks, very helpful. Just got my 7x14 mini lathe and was looking at setting it up with Mach3. Off to look at your other videos. New subscriber
Cool. Mach3 is great but Mach4 has a lot of improvements, especially for lathes. I'm in the process of converting my lathe over to Mach4.
Hello Franck I couldn't find the details about
Magnetic rpm feedback please advise

How do you get them reading the same please
Lathe 500 rpm
Mach 3 1000rpm
Did this sensor work with the Centriod upgrade or did you have to change to a new sensor?
