I'm a new bee at CNC. Finaly a teacher I understand. From this lesson I understand what limit switches do. Would you do a video on how to wire up a limit switch. Your calm persona I can identify with. I'm also an old dude and CNC is going to be a huge learning curve for me. So far, I'm amazed that I'm able to retain as much as I have.

Thanks so much. Too often so called experts attempt to pero something quite complex. Most often they dont speak clearly, zoom the camera all over the place, or just click through screen shots. Your approach is so good. Everything is so clear and well explained. Just finishing a home made 48" x 48" router-plasma-laser and what ever. Wish i had viewed this prior to ordering proximity switchs.

Basically total noob here, I got some machine things happening where it costs me money in mistakes and also my own in-experience that costs me money. When the machine starts a cut path above a sacrificial slat, this actually effects the hypertherm and I did read from Jim Colt, that this is a common problem with the Hypertherm 45XP. So after it stops / has an an "E-Stop" error, this can throw the machines coordinates out as the E-Stop is reset, as the magnets in the stepper motors re-power and move to their natural position, ready to start moving again after I command it to start again. This exact same thing happens every time the machine has a fault light / E-Stop, which is the biggest cost to my operations so far. So as you can imagine, the E-Stop / Faults in my cnc plasma are very frustrating and I'm now trying to rid the machine of what ever faults I can. Another issue I have is when the machine moves from one cut path to another, I'm sure these movements are called "Rapids". So If I'm cutting out a car picture, imagine the machine has cut out all the interior cuts like the wheels, the windows etc, then it moves the Z up and moves over to start cutting the outline / body of the car, it will fault on that movement when in the middle of the transition from one path to another. This throws out where the machine thinks it is, so as I tell it to start that next cut, it may be off by about 12mm on the X and Y, this will start that next cut from a position that is totally wrong and the design of the car is totally off. Really costs me money, very frustrating. So I guess your homing and limits switches would help me here in zeroing the machine again, but it's still probably hard to do when it's not starting a fresh cut on a new plate. I need to slow down my rapids, then maybe upgrade the machine to have these limit switches, as I only have one on my Z Axis.

This is a very confusing subject for a newbie. When one also considers setting center for a job, it adds to the brew. The work here is developmental in nature and currently am working on a prototype that is actually @ 5x8 inches . Since there are varying depths with varying bits and 12 separate parts to make up the entire 5x8 prototype, I am having to make test cuts. So, I placed a level board that is @ 12 x 24 inches. With this there is plenty of room to make test cuts of the various sections before making the actual cuts in the 5x8 piece. Where it gets wierd here is that a message comes up that insists I am out of limits when there is ample room all around where am setting up either the test cuts or placing cuts into the prototype piece. Win PCNC is being used here. I usually set a centering point (XYZ coordinates) for the area of the base material/board I am doing the work on in winpcnc and the coordinates get saved. The actual file is brought in and the centers line up. There are times here where the machine seems to refuse to hold coordinates and or I get messages saying am out of limits. There are magnet limiting switches and I would like to know if I can set up some coordinates so the out of limit warning doesn't come up? I got this machine some 8 years ago and have had to teach myself everything. Win PCNC isn't popular in America. The tutorials, although recently more plentiful, are in mostly other languages...German, Hispanic, Polish,...

I’m adding home and limit switches to my CNC and need to understand the procedure. I have two switches on Y Home and Y- - and one switch on Y + +. After setting steps per inch and squaring the CNC. Bothe the Y home and Y - - be made at the same time, Correct? Or just close? I have a positive stop at the end of the travel of all axis. I understand the travel (when homing) will slow and contact the positive stop then back off a little. Which location is home, the positive stop, or the location that it backs off to? How do you set the point that it will slow down, and how do you set how much it backs off? MACHINE COORDINATES, in Y axis in zero at the front of the CNC, and 36” at the rear of Y travel, if you have 36” Y travel. Where and how do you enter the zero and the 36”? I’ve use my DIY CNC for 12 years and never had a problem with setting XY Z zero, but I want to use the exact positioning of the axis especially with tool changes so as to have the different bits register as accurately as possible. Sorry for asking so many questions, I really do enjoy your YT videos, very straight forward, without getting sidetracked , thanks so much .

@nkronert4 жыл бұрын
It would be nice if the limit switch would kill power to the motor directly, without relying on software that may hang after switching the motor on :-). Of course this has to be done in a way that still allows the motor to run in the opposite direction in order to get out of the situation. For DC motors driven by an H-bridge I think this is possible by routing the control signals through the limit switch, but I still have to test if that actually works.

We have an "A" motor slaved to the "Y", and a limit switch mounted on the "Y" side. When we reference all home, the "Y" side will move to the home position. But the "A" wont move. When I trick Mach3, and tell it that the "A" motor has a limit, it moves along with the "Y". But it keeps wanting to move, until it finds that limit (which is not there). Do I need another limit on the "A" side? Or is there another setting in the program?

I wish someone would post a video on powering up Home Switches correctly. I am using the Gecko G540 with a UCCNC 100 USB Interface and Proximity Sensors that are wired Normally Closed. However when I wire them Up I am required to run a seperate power supply to power the switches. I am using a Wall Wart to supply the power and everything is grounded through my 48V Power Supply. They'll work perfectly as long as my E-Stop Switch is Engaged, however when I Open the E-Stop Switch they refuse to work as described. I haven't found anyone who can explain how to correct this.

Provided the switches are wired correctly I feel it may be the setup you are using in mach. Have you monitored the home pins while the estop is depressed and pressed. How about changing the ports and pin configuration for the home to the opposite of what it is now, such as active high.
