When the engraving machine lifts the knife, the Z axis automatically goes up to a depth of 2mm

Is the coupling driving the screw or the belt driving? , if the coupling is tight, see if the coupling screws are tight. The belt is to see if the belt is loose.

Most of your phenomena are caused by virtual connections. The engraving machine uses g** when working, that is to say, every time the engraving machine moves, how far it moves, it is necessary to use g**. The kind of phenomenon you mentioned is when the computer transmits ** to operate the machine, and the machine does not respond.

So you have to check what is affecting the signal transmission. Either the data line or the driver is the first thing to be checked. You can also listen to the sound when carving, whether there is a freeze or pause.

When I repair the engraving machine, most of your phenomena are connected to the terminal posts on the driver, you can refer to it.

Your kind of problem should be that the machine has lost steps, which we call misalignment.

During the engraving process, if it is horizontal bottom washing, of course, it is no problem, because at this time, the Z axis does not need to move.

Workaround:1. Check the connection line from the Z-axis motor to the driver and each plug to see if there is any loose virtual soldering that causes poor contact.

2。Check whether the mechanical part is stuck, twist the screw or rack by hand to see if it is flexible in the state of power failure, and put some oil on it after inspection.

3。Check whether there is any slippage of the belt, coupling, pulley, etc.

4。Whether the parameters in the software are set properly, including pulse, maximum speed, take-off speed, and single-axis acceleration. The parameters should not be set too high, the stepper motor is fast and it is easy to lose steps.

Dear, sorry to wait for a long time, for you to find out if the engraving machine engraving is more than 4mm, it may be because the engraving head is not fast enough, so that the process does not have an accurate effect. It is advisable to check the speed setting of the engraving head to achieve the desired result. First, make sure that the engraving machine is properly installed and that there is no additional noise or vibration.

When diagnosing the speed of the engraving machine, the speed of the engraving head can be set using the adjustment tool of the engraving software to achieve the best performance. In addition, you can change the position of the engraving head, try different tool materials, and the temperature of the tool to better control the accuracy of the quasi-guess tape.

Summary. After the engraving machine is completed, it will automatically return to the origin of the workpiece, according to what you said, I estimate that there are two possibilities: the first is that the workpiece is thicker, the z-axis stroke is smaller, and the second is that your lifting distance is set too large.

In this way, when the machining is completed, the range of travel is exceeded when the tool is raised, so it is limited.

After the engraving machine is completed, it will automatically return to the origin of the workpiece, according to your Min chain method, I estimate that there are two possibilities: the first is that the workpiece is thicker, the Z-axis stroke is smaller, and the second is that the distance between you and the knife is set too large. In this way, when the machining is completed, the range of travel is exceeded when the tool is raised, so it is limited.

Can you tell us more about that?

After the engraving machine is completed, it will automatically return to the origin of the workpiece, according to your Min chain method, I estimate that there are two possibilities: the first is that the workpiece is thicker, the Z-axis stroke is smaller, and the second is that the distance between you and the knife is set too large. In this way, when the machining is completed, the range of travel is exceeded when the tool is raised, so it is limited.

One is that the limiter is touched (the solution is to remove the Z-axis limiter line in the electric frequency box, and the second is to set the height of the knife to change the ridge to a smaller degree), and the other is to reverse (the solution is to hold down the crack Ctrl+Shift+Alt+Right and click the Z-axis drop-down menu to reverse, and then restart the software).

Summary. Hello, dear, the z-axis of the engraving machine automatically sinks or rises as follows: 1. Check the control board of the woodworking engraving machine to see whether it is loose or has signs of damage; 2. Eliminate the interference of static electricity or surrounding magnetic field; 3. If there is a problem with the Z-axis motor line, replace it with a new one and eliminate it; 4. Whether there is a problem with the engraving toolpath file; 5. Whether the inverter causes interference work; 6. Check whether there is a virus in the computer that controls the woodworking engraving machine; 7. Clarify whether the operation mode of the woodworking engraving machine is appropriate;

When the engraving machine is turned on, it will be zeroed, and then the XY axis will not move, and the Z axis will automatically move up and down.

You slip and rush well, dear, the z-axis of the engraving machine sinks or rises slowly from the limbs as follows: 1. Check the control board of the Muxin Jerry engraving machine to see if it is loose or has signs of damage; 2. Eliminate the interference of static electricity or surrounding magnetic field; 3. If there is a problem with the Z-axis motor line, replace it with a new one and eliminate it; 4. Whether there is a problem with the engraving toolpath file; 5. Whether the inverter causes interference work; 6. Check whether there is a virus in the computer that controls the woodworking engraving machine; 7. Clarify whether the operation mode of the woodworking engraving machine is appropriate;

The Z-axis should be changed and rectified: 1. The inverter and filter 2. The inverter and the spindle motor should be replaced with shielded wires, and the shielding network should be grounded. 3. The lead dust inverter calls the power line and motor line with magnetic rings.

4. The power cord of the inverter and the power cord of the engraving machine are divided into sockets, and the connecting line with the stepper motor is used to avoid flat walking lines.

Hello, the z-axis of the engraving machine will automatically sink or rise, there may be the following reasons:1Sensor failure:

Some engraving machines are equipped with a height sensor, which can cause the z-axis to automatically sink or rise if there is a problem with that sensor or it is damaged. You can check if the sensor is working properly, or replace the sensor to fix the problem. 2.

Bearing or slide problems: If there is a problem with the z-axis bearing or slide rail of the engraving machine, it may cause the z-axis to sink or rise automatically. You can check that the bearings and slides are in good working order, or replace damaged parts.

3.Circuit board problems: If there is a problem with the circuit board of the engraving machine, it may cause the z-axis to sink or rise automatically.

You can check if the board is working properly or replace a damaged part. 4.Program Settings High Dust Problem:

Sometimes, the program settings of the engraving machine may cause the z-axis to sink or rise automatically. You can check if the program settings are correct and try to set it up again. If you can't determine the specific cause of the problem, it is recommended to contact the engraving machine manufacturer or professional technicians for overhaul and repair.

At the same time, in order to ensure the normal use of the engraving machine, please follow the operation manual for correct operation and maintenance.

Summary. Hello, the computer engraving machine back to the mechanical origin of the Z-axis limit trigger may be the following reasons, it is recommended to find a professional to overhaul.

1.It is possible that the limit is broken.

2.It is possible that the line of the limiter is broken.

3.It may be that the sensing limit is far away and is not sensing.

My computer engraving machine back to the mechanical origin z-axis limit trigger what's going on.

Hello, the computer engraving machine back to the mechanical origin of the Z-axis limit shouting trigger may be the following reasons, it is recommended to find a professional to overhaul. 1.It is possible that the limit hall was broken carefully

It is possible that the line of the limiter is broken3It may be that the sensing limit is far away and is not sensing.

None of these problems exist.

Hello, if these problems do not exist, it may be that the limit switch is broken, and it is recommended that it be better to be dealt with by professionals.

The limiter is good, and it is the same for a new one.

If it is Weihong software, it should be the manufacturer's parameters - motor parameters - Z-axis pulse equivalent is not right, according to the specific machine, the general screw machine, the rack is in. Of course, there are others, you can't ask me specifically, of course, the premise is to adopt.

The actual cutting depth of the engraving machine is deeper than the computer programming requirements, mainly due to the inaccurate measurement of the starting depth of the tool.

In the process of engraving machining, the programming starting depth of the Z-axis must be consistent with the actual depth, if it does not match, it will cause the actual cutting depth to be greater than or less than the programming depth, and in serious cases, it may also cause the machined parts to be scrapped.

The reasons for the inaccuracy of the starting depth are as follows: the Z coordinate measurement of the starting position of the tool is not accurate, the actual length of the tool is inconsistent with the length of the programmed tool, the tool tightening force is insufficient, and the tool moves during processing.

The method to solve the inaccurate processing depth: first of all, the important parts should be tried to cut first, and the formal parts should be processed after the test cutting parts are successful. A measuring platform is left at the edge of the workpiece, and the measurement platform is processed first, and the rest of the part is processed after the depth dimension measurement of the platform is qualified, so that the workpiece can be avoided from being out of tolerance or scrapped due to various errors.

What is the program to be programmed, is it NC format, or PLT format, set the manufacturer's parameters, and the motor parameters Z-axis.
