If you have found this video to be helpful, consider making a tip. Thanks.
This is a primer on setting up limit and home switches for a CNC machine. Focus will be on the concept of wiring for NO (normally open) and NC (normally closed) techniques and using the bit as the reference for the homing.
Equipment that I use to make videos:
Canon EOS Rebel: amzn.to/2rJSeh0
Macro Lens: amzn.to/2qaSKmK
Microphone: amzn.to/2qO2RB4
3D Mouse to rotate/zoom/move the object (Must have for CAD!!!): amzn.to/2ruFnSn
The drafting pencil I use on these videos: amzn.to/2qioYg2
The cheap oscilloscope that I use (because it's cheap and will work all of the projects in these tutorials): amzn.to/2rSHnBa
A better oscilloscope and the one I would recommend: amzn.to/2qizK5M
The brand of multimeter that I use and the one I recommend: amzn.to/2qicUez

Well it's a common style of vloggers to basicly say a sentence 15 different ways and then splitting all those clips in 15 pieces, and showing a piece of every clip, so it completes into a sentence. It's a very distinct style and takes practice to master. But you're getting there!
putting my limit switches on right now! my bluechick is awesome. im obsessed with this now, all those years of not being able to do government jobs on work machines, now i can do anything!
Great job sir thanks
Thanks. Yes, I went editing wild! I get comments that tell me to do the editing, so I try to remove as much of the pauses as possible. I have no experience with vidoeing or editing, so bare with me as I get experience. I will try to retain some balance of pauses, but I do agree that it is a bit tenuous.
Amazingly well explained, I also love the detail of your build log.
Thanks! Comments are a great motivation to steer my technique. :)
Great Patrick, excellent work, thanks for expanding our knowledge, sharing your own one handles very precise and clear, thanks
@KritikalDimensions Great! Hope everything goes well.
@devilmastah Yes, I know. This video was made a while ago and I have learned since then.
That is true in my case too, due to trying to think of the most accurate and appropriate phrase. I must say that it is a tedious exercise, but it beats stopping the camera and deleting frames.
Thank you for replay !
Thanks for that video! you helped me a lot with my CNC !!!
Patrick,
Thanks a lot for all the wonderful videos you have created regarding cnc. I subscribed :)
I have been reading threads on home and limit switches. All seems pretty straight forward how i need to clarify before i start wiring and get my hands dirty.
Question/s:
1 - As I understand there are two schools of thought for home/limit wiring, one is to wire X Y Z on separate pins with a common across each axis.The other, using a single pin (1) across all axis.
A - Advantages / disadvantages to each (using Mach3)?
B- Does the actual switch configuration matter (NC or NO)?
2 - With a probe, do you really need Z home and limit?
This is a great info-packed video but it's coming at you at 100mph it's making my brain explode :-) Awesome info though
Why when I press the botton " Automated setup of inputs" there is a little windows that says, "this is only for the printer port modes!" I don't kmow how to get to this sittings of the axes, Can you help me ? thank you for your response.
Thanks!
Thanks!!
im having a problem , built a machine for wall paper , but i want it to cut every 5 meters and i cant do that unless im getting out of the grbl hope u understand what i mean any i dea how to do that by using a switch or any electric measuring tool that can be connected to the grbl so i can keep it continues running?
great video, really thanks for your time...
looks like mach3 is prepared for everything.. I used mach3 for short year or so.. since then I usng ncstudio,,
however I need to back mach3 because I want to add axises..
thank you again for your effort
I got a question,, I got my switch on my machine and they work fine, but when the machine reach the switch they stop and they work fine couse that the job of the switch, but my doubt its i have to move my axis manual or the machine will go to home when the switch itas hit it? need some help
hi, im using my normally closed ( NC ) limit switches connected to breakout board and I get constant false limit switch trips . im using shielded wire. what can i Change in Mach3 to not have this problem.
Thank you
Hi Sir, I noticed this option not function in Mach3 breakout board USB BOb
Which function? The Autoset function?
@@PatrickHoodDaniel Yes sir
there is a dialog box appears , this option only for the printer port modes!
how we can let the mac 3 know the size of my work bed,should I measure the total sizes and input it in to the mac 3 software.please advice..thanks in advance..
I have done a few multiple clip videos. For those I have found its cleaner to add the voice over after the video is finished.
Very helpfull. Thanks
I have built one cnc router, with four motors, 1 for z, 1 for x, 2 for y. Start machine to go home, for z all well, for x all well in y when 1 motor terminate starts the next (this is wrong because it clonus). Where is my mistake ? ( google translate ) thank you
Man this video must be shooting up speed or something,, I had to play it at quarter speed to make sense of it LOL. great info though.
good job ! i like it
I followed your steps for homing and machine would not back of from switch
hi when I hit the auto setup inputs signals button maxh3 says this is for printer port only? and will not open the next page where you go the settings ?
If you are not using a parallel port for the communication to the CNC, then you will need to set up the inputs manually.
Can i use the X-- limit switch for homing or i have to put anothe switch?Thank you in advanced.
Yes, you can use the limit switches as both home and limit switches, even if they are on the same input pin.
Thank you for the fast respond, great videos my friend, you helped me alote with my G0704 CNC convertion.
You're welcome and thanks for watching!
What if I'm running the Ethernet smooth stepper says can only run automatic setup in printer port mode
The automatic setup is only available if the software has direct connection to the limit switches. The parallel port has a direct connection to the limit switches. Mach3 cannot determine the state of a limit switch through an Ethernet or USB as these are made for instruction and the limit switch states goes through an external device (the smooth stepper).
Here is another way to think about it. The software is processed through the CPU and the parallel port is directly connected to the CPU (similar to GPIO pins). When Mach3 polls the specific pin (through address calling), then Mach3 can directly determine the state of that pin. The pin may be connected to a limit switch (input pin), or an output stated like a pulse for the stepper motors, or turning something on or off.
Patrick Hood-Daniel so there is no way to run limit switches with the smooth stepper? I just need it for the z homing. I got the smooth stepper because Windows 10 parallel port is non functional any advise ?
No, I was referring to your question regarding "automatic" setting. Go ahead and use the manual setting approach according to the smooth stepper instructions.
Patrick Hood-Daniel on my c10 breakout board I have zero 5 volt power from pins 10 and on could the ess be preventing my limit switches from working? Or the pull up pull down? Idk would adding a jumper with 5v be a bad idea ? Trying to get my floating torch plate working...any help is appreciated
Patrick Hood-Daniel does mach3 make my Wi-Fi disappear on my computer even after I created 2 separate networks ? This is the second computer where my internet capability disappears after using mach for a few days
Great information but less with the editing, its is just to much information to quickly, pauses are good, lets people digest what you have said, it also makes you sound like a computer generated voice.
Thanks. This is an old video. I was still learning and had no idea what viewers really wanted.
Good video, but you shouldn't cut it every second, that makes it kinda annoying to watch :)
Jesus could you speak any quicker. Great information but just too quick dude!!
my goodness could you say it much faster............to my drugs dude...........
