Introduction to Manual Movements (0:00-1:12)

0:00-1:12: “Hey, hey, welcome to another training video. Today we’re gonna cover manual movements, specifically how to do that with your controller interface and hotkeys on the keyboard to move your machine in any of the automated axes pertaining to the system. So let’s go get started. Once your machine has been powered on and the startup routine has been complete, uh, we can get access to manual motions on any of our screen interfaces that we typically use. For example, here on the home screen, we have, um, all the automated axes, X, Y, Z, and A. You can see here the B axis for tapering, uh, is manually controlled. So we have four AEs of automation. Technically, if we go to any of these workstations such as the horizontal workstation, we still have the same AEs of control, except here on the horizontal and vertical. Um, the a axis is not being used on those workstations. And so on the vertical, we’re gonna have the same layout for the A axis being kind of disabled. So we have X, Y, and Z. If we go to the turning center, we then have, again, all four AEs of automation. It doesn’t really matter what screen we’re in to move the machine with the controller. Uh, for example here, if I’m in the turning screen, I have the A axis, I have the plus”

Controller Interface for Axis Movements (1:12-3:10)

1:10-3:11: “I have the A axis, I have the plus and minus directions for that axis right here in the controller. So if I push, for example, the left arrow button, it’s gonna move the machine to the left. And when I let go of that arrow button, it then stops moving and vice versa. If I push the right arrow button, it moves the machine to the right. So this is the positive X direction. This is the negative X direction, and that’s the same here for the Y. So here’s the negative Y direction and here’s the positive Y direction. We have a negative Z direction and we have a positive Z direction. Okay? And since we’re in the turning center, we can also rotate our turning center as well. If we push the counterclockwise direction, the aax, the A axis will rotate counterclockwise and vice versa. Here’s rotating clockwise. Now, these motions of control are all the same, meaning that if I hold down the button, it will continually move along that axis until I let go of that button. Now let’s show you the same commands on the hot keys for the keyboard, For the delta controllers. Uh, the hot keys, instead of being tied to the arrows here, like the mach three systems, they’re gonna be tied to the arrows here on the number pad. So we have the same arrows, a left and a right to do negative X and positive x. We have an up and a down to go positive Y and negative Y. And we also have the page up and page down to do our Z axis. So positive Z, negative Z If we’re in our turning screen, we also have the seven in one tied to home and end to rotate the A axis, we have a counterclockwise and clockwise motion. Now, if we push these, nothing will actually happen on the machine. It requires an additional key command to be held down, uh, for this to take place. And that is the control key. So you’ll need to hold this down the entire time”

Hotkeys for Manual Control (3:10-4:59)

3:08-4:59: “So you’ll need to hold this down the entire time as you’re moving the machine manually with the hot keys. And we don’t wanna let go of the control key and we’ll explain Y in just a moment. So I’m gonna hold down the control key and for example, here is positive x. Here is negative x here is positive. Y here is negative y, here is negative Z. Here is positive Z. Here is counterclockwise A and here is clockwise a I previously mentioned that we’re going to be holding down the control key the entire time as we’re moving the machine with the number pad hot keys. If you don’t, I want to show you what can happen and how we can resolve it. If by chance you run into that situation, um, if you, um, press the control key down and then move the machine and then let go of the control key while you’re still holding a a command down, it’s gonna lock in that command access. Even if you let go of all the buttons. Let me show you what I mean. And I’m gonna be using the emergency stop switch just to show you how we can, um, how it, um, overrides this command, even if that takes place. Okay? So I’m gonna hold down the control. I’m gonna move the machine in the positive xaxis direction, and I’m gonna let go of the control in the wrong order. Okay? So you can see that even though I let go of all the buttons, it still wanted to move in that access. Now my e-stop is pressed in. If I let go of my e-stop temporarily, I’m gonna push it back in afterwards. You can see I didn’t push any commands and the machine wanted to continue moving. So it’s locked in this motion if the emergency stop switch is not. Now to get it out of this, we’re simply going to repeat what we did in the command.”

Resolving Locked Axis Movement Issues (4:59-5:51)

4:58-5:51: “what we did in the command. So we’re gonna go control, hold the axis that we had told it to go into in this case positive X, and then let go of control in the right order. So let go of the axis command and then control is always last. If you follow that procedure where you push control first and then let go of control last, you’ll never run into this locked axis movement situation. But now we’ve, uh, we’ve fixed that. If I turn off my swi, you can see the mach, the machine is no longer, you know, wanting to move by itself and I can freely move it anywhere else. So just keep hold, keep that control key down, and you’ll never run into that situation. Okay? By understanding those commands on the control interface as well as the hot keys on the keyboard, we can now position the machine anywhere we want it to be, um, while manually controlling it.”
