Introduction to Jogging Techniques (0:00-1:12)
0:00-1:08: “Hey, hey. Welcome to another training video. Today we’re gonna be covering how to control our manual motions in two different ways with constant jog and step jog. Another thing we’re also gonna cover is movement speed. ’cause as we’re moving the machine with our constant jog, sometimes it may be too fast and we need to slow it down, um, to one, be more comfortable with the movements or be a little more precise as we’re locating positions. Now in the controller, we can be in any of our workstations to control both the constant jog, step jog and movement speed. Um, in this particular demonstration we’re gonna be doing the horizontal table, uh, because we’re going to be setting up an XY zero location for a part on the horizontal workstation. So let’s show you where this is at for a quick review. Um, in the previous video we showed that these buttons here moved the axes in those particular directions, positive and negative directions. And we also had the hot keys that did that, did the same thing. Now this mode right now, as long as we’re holding the button down, let’s say I hold negative X down,”
Constant Jog Functionality (1:12-2:28)
1:12-1:35: “It will constantly move as I’m holding that button down ’cause it’s in constant jog. Um, we can control it in another type of mode called step jog, but we’ll get to that in just a moment. Um, this is moving at 100% speed of what has been programmed for these motors at this time. So again, if this is too fast for you at the beginning,”
1:38-2:14: “You’re not comfortable with those speeds. Or perhaps that when you get close to setting up a zero location and the cutter’s just really jumpy ’cause it’s moving too quick. Let’s show you how we can override the movement speeds. And that is right up here. Um, under the display screens, we can go to the control display screen and here we have what’s called a jog feed rate. And you can see this is listed at 100% right now, is what that number represents. If we click on the number, we can change this percentage. So let’s say I only want it to go 20% of the movement speed value, okay, based on speed. Now when we move our machine,”
2:17-2:28: “We can see it’s a lot more controlled, um, based on what we’re trying to do. So we can adjust this percentage of our jog feed rate to accommodate whatever situation, you know, comes our way.”
Step Jog Functionality (2:28-4:05)
2:25-4:06: “to accommodate whatever situation, you know, comes our way. Now for a step jog that is located directly underneath of this. Now if we click on that, it will activate and you can see the light turns on. If I click on it again, it will deactivate. So if step is turned off, we are in constant jog, which is what we just barely showed, um, with the machine moving constantly as we’re holding that button down. However, if we press the step button, now when we actually push the button here, even if I click and hold, it’s not gonna continually move. It’s only gonna move a specific distance amount. Um, every time I activate the button just once, um, even if I hold it down, I’m still only activating the button once. Now the increment that we’re moving is to the right of step jog here. So I was only moving 0.001 inches, which is 1000th of an inch. You can actually see our uh, DRO move here. If I push the button, you can see that went over one thousandths of an inch. I can control the increment of my step jog by clicking the plus. Okay. It’ll kick up my per uh, my uh, distance here up to one inch. So now we can see as I uh, press positive x, it moves one inch in the positive X direction. And if I need to go less than that 0.1 inch, and if I need to go 10 thousandths and if I need to go one thousandths of an inch, it will move one thousandths of an inch at a time. Okay? So we can be very precise with our step jog when locating an exact position. So using these um, controls, let’s go find the corner of a part as if we’re setting up our XY zero position.”
Positioning Tool for XY Zero (4:05-6:44)
4:02-4:52: “of a part as if we’re setting up our XY zero position. So for this demonstration, we’re simply gonna take a apart. I’m gonna position position it closer to the camera so it’s easier for you guys to see. And we’re gonna make this corner here, which is technically the bottom left corner from the front of the machine. Um, that’s gonna be our XY zero. And so we’re gonna position the tool, I put a 90 degree v cutter in the spindle and we’re gonna position the center of that point right over this corner and make that XY zero using both constant jog and step jog commands. So in the controller, I’m going to turn off my step jog so that we’re moving the machine, um, in a constant jog position. So now I’m moving at 20% maximum speed.”
4:55-6:22: “And if that’s too slow, guess what? You can speed it up. I can go back to my, um, jog feed right here. And let’s say I’m gonna go up to 50, enter now when I move my machine, okay, gets there a little quicker and we’re going to now start bringing this close to this corner. Now as I’m moving, I may notice it’s a little jumpy just ’cause it’s in step jog. I’m sorry, it’s in constant jog. We’re gonna go back to our controller. We’re gonna go to this step jog and I’m gonna bring it up to 0.1 inches. One thing we need to be aware of is if I only have a certain distance between the tool and the material, I’m not accidentally going to be moving my cutter past that amount. So for example, I have less than an inch here, so I’m not use one inch step in, um, in my controller, um, or else I could accidentally drive this tool into my material. So I’m gonna go less than that. So in this case, I’m using 0.1 inches as my step was step jog activated. So with our step jog at 0.1 inches, let’s now dial this puppy in and get it closer. Okay? And now that I’m pretty darn close, I’m gonna go to my step jog and go down to 10 thousandths of an inch 0.01 inches and I can really dial this in.”
6:29-6:44: “And there we go. Now, if I was to finish the process of zeroing out my axes, I could come over here and zero x and zero out y. Um, because the center of my cutter is over the corner, which is the perfect position for the XY location.”
Finalizing Setup (6:44-7:05)
6:41-7:05: “which is the perfect position for the XY location. And we have now completed that process successfully using our step jog, constant jog and jog feed rate settings. So go give that a try and you should now be able to position your tooling anywhere you want quickly and also accurately to a precise location anywhere within the work area of the machine”
