The engraving machine shows what is going on with the processing exceeding the Y negative limit

The engraving machine has a variety of data input modes that can be easily adapted to meet your needs. It is compatible with a variety of engraving software, and can also be compatible with JD software in engraving machine ENG format. The arc optimization command of the engraving machine can automatically eliminate the velocity chatter according to the characteristics of the workpiece.

The traditional CNC control system often has the following problems: the curve speed is slower than the straight line speed, the curve accuracy is worse than the straight line, the machine jitter is very strong and the speed is slow, and the accuracy is poor. The application of this control system effectively solves this problem, which not only improves the processing efficiency (the processing time can be shortened by 30%-300%), but also eliminates the speed chatter mark and improves the processing quality.

The engraving machine adopts widened high-precision cylindrical linear guide rail, which has good stability and high precision. The processing stroke is more than 160 mm, which is higher than other equipment, especially suitable for making blister molds, contracting semi-finished products and ...

This means that the machining range of the Y-axis direction of the workpiece you are machining exceeds the stroke of the machine. You can consider the following points: 1. Check whether the position of your workpiece origin is consistent with the position of the programming origin, for example, the programming origin is in the center of the workpiece, and the position you set is in the lower left corner of the workpiece or other positions.

2. Check whether the processing size of the workpiece exceeds the stroke of the machine tool. 3. Whether the position of the origin of the Y axis is too close to the zero point, if the machining size is within the range of the machine stroke, re-set the position of the origin of the workpiece Y. I don't know if Beijing Juntai Jingdiao can help you.

The starting point of the work is not accurately positioned.

Hello, this means that the machining range of the Y-axis direction of the workpiece you are machining exceeds the stroke of the machine. You can consider the following points: 1. Check whether the position of your workpiece origin is consistent with the position of the programming origin, such as the origin of programming is in the center of the workpiece, and the position you set is in the lower left corner of the workpiece or other positions.

2. Yu Qiao checks whether the processing size of the workpiece exceeds the stroke of the machine tool. 3. Whether the position of the origin of the Y axis is too close to the zero demolition point, if the processing size is within the range of the machine tool stroke, re-set the position of the origin of the workpiece Y.

The handle engraving machine Y axis is always negative and the limit may be caused by the following reasons:1Loose mechanical parts:

If the mechanical parts of the fierce code handle engraving machine are loose, it will cause deviations when the Y-axis is moving, resulting in negative limits. 2.Transmission belt slack:

If the drive belt of the handle engraving machine is relaxed, it will also cause deviation when the Y-axis is moving, resulting in negative limiting. 3.Which motor is faulty:

If the stepper motor of the handle engraving machine fails, it will also cause deviations in the Y-axis movement, resulting in negative limits. Workaround:1

Inspect the mechanical components to ensure that they are firmly connected. 2.Adjust the drive belt so that it is tight.

3.The stepper motor is inspected and if a fault is found, it needs to be replaced or repaired. In addition, it is also necessary to pay attention to the operation method of the handle engraving machine to avoid the Y-axis deviation caused by improper operation.

If the above methods cannot solve the problem, it is recommended to contact the manufacturer or after-sales service of the engraving machine before the handle is closed.

If you exceed the limit, hold down the overtravel button, and press the opposite direction of the overtravel axis, you can consider the following problems:

The motor is switched to another shaft and see if the motor is broken.

See if the three controllers are broken.

Check whether there is a place where the screw or rack is stuck in the direction of the Z-axis, and the torque in the stuck place is too large, and the Z-axis may not move.

Check thoroughly with a multimeter, the corresponding line has no power, if all the corresponding z-axis lines are energized normally, change the card and try it.

See if it's a pirated version of Macro. See if the little green card connected to the computer cable is broken. Swap the Z pulse and direction line with the Y pulse and direction line, and the Z axis on the point computer is the Y axis, and see if the Y axis is moving.

Swap the signal line of ZY and move the Z-axis Y-axis, which basically eliminates the fault of this small card. It is recommended to reinstall the control software first, and try to change the slot of the control card in the computer. If it still doesn't move, it is estimated that the control card may be faulty.

This kind of high-imitation card is relatively cheap and will not exceed 200 yuan. You can buy one, and even if it's not a card failure, it's still useful to have one back in the future. (Yes, after debugging, the z-axis and y-axis are moving, so that it is not the fault of this small card.)

It may be that the Verhong card is faulty, but it can't be so sure that the Verhong card is faulty. Because this kind of Macron card is highly imitated, sometimes it will have problems if it is not in good contact with the slot of the computer. You can buy a card on ** to try, more than a hundred dollars.

If you still can't move after the limit is released, you can consider that the limit switch may be broken or not in good contact. Try to change a new switch, there are sales in the electronic market, generally called a travel switch or a proximity switch. Less than ten bucks.

When changing the switch, it is better to change the polarity back to the original state, and do not reverse its polarity under normal circumstances. (If you don't have a limit switch, it is likely that the control card is faulty.) ）

It also depends on whether the limit is mechanical or inductive. If it is inductive, it is necessary to see whether it is normally open or normally closed, and see if there is any problem with the card and data cable, which will cause problems.

The same thing happened with this engraving machine in my house.

I don't know, what kind of engraving machine yours is, according to normal speaking, if you exceed the limit, just press and hold the overtravel button, and press the opposite direction of the overtravel axis!!

Summary. Check the path you gave first, and see if there is any problem with the path command and whether there is a limit.

Check the lead screw or track to see if there is any debris stuck.

There may be a problem with the Y-axis controller or control card, check the connection cable between the engraving machine and the computer.

When the engraving machine was working, the Y-axis suddenly limited and stopped.

After a while, the engraving machine returns to the mechanical origin, and it can work normally, sometimes good, sometimes bad!

Dear, this is the problem of poor contact.

You can't fix it yourself.

It needs to be repaired professionally.

Oh! Okay pro.

Thanks dear. Thank you!

You're welcome, it's my pleasure to serve you.
