"I never expected that the first thing I did when I got home was to fix the milling machine."

Squatting in the backyard workshop, Ye Ming disassembled this Heidenhain's TNC155 CNC milling machine and carefully put the screws and parts in order.

My father brought an electric fan behind him, but in this weather, even if the fan was blowing, it was still blowing hot air.

On the contrary, the neighbor uncle who heard the news and came to see the excitement was not too hot at all, and asked curiously next to him.

As a guy who eats at home, this milling machine has been seen by someone after it was broken, and it was said that it was a motherboard problem, and it was necessary to return to the factory to replace the motherboard.

"Dad, you should find a cool weather to call, I'll be back with a ride."

"Boss Ye, listen, I told you at that time that you called Ming Wa'er, but you didn't believe it." Uncle Zhu, a neighbor, smiled and squatted aside: "Mingwa's action has been practiced in school at first glance, and if nothing else is said in the future, it is also a high salary to eat the bowl of rice repairing machine tools." ”

"You'll just listen to him!" Ye Qigang also squatted beside his son, picked up the screws and nodded: "Missing screws?" ”

"I guess it was the person who repaired it for you last time who trimmed it, and I will match it later. Dad, did the maintenance master really say that the motherboard was broken? Ye Ming had already taken off the PLC motherboard at this time, and took it in his hand to look at it.

"Hmm."

"Then I'll take it inside and test it."

Ye Ming got up as he spoke, picked up the motherboard and walked to the "office" at the entrance of the backyard.

Although there are three words written on the door, there is no office appearance, to be precise, this is Boss Ye's workshop.

Ye Ming's robotic arm was born here.

The workshop is small, the walls are covered with tools, the screwdriver wrench alone is long, and the corners are piled up with various materials and scraps.

The workbench was disorganized, and when you touched it with your hands, there was still dust on it.

Ye Mingjiang wiped his hand and asked with a smile, "Dad, how long have you not been to work?" ”

Before his father could answer, Uncle Zhu next door preemptively said, "What kind of work are you going to, business is not doing well now." ”

Ye Ming was stunned when he heard this, and turned his head to look at his father: "Isn't business bad?" ”

The father laughed and said, "How can there be a business if the machine is broken?" ”

Ye Ming frowned slightly: "It's just that the milling machine is broken, you can't do any work......

Uncle Zhu said again: "It's not to make money, it's better to make money by delivering takeaways." ”

Ye Ming was suddenly surprised, and looked at his father carefully: "Dad, you won't deliver takeaways, right?" ”

Father was suddenly a little unhappy: "You can't be your dad if you deliver takeaways?" ”

“…… No, it's so hot, and it's all young guys who send ......."

"So I'll come back and rest when it's hot." Father touched Ye Ming: "Cultivate you, how can you have so many words." ”

……

After learning that his father, an old car worker, ran to deliver takeaways, Ye Ming did feel a little uncomfortable in his heart.

By his father's handiwork...... It is definitely better for him to find a random place to work than to be outside in the wind and sun.

Obviously, this is not a problem with a single milling machine.

Something must be wrong.

After a moment of silence, Ye Ming took out the sensor from his pocket, and without explaining to the two people around him, he stuffed it directly into his ears.

"Ita, help me find the drawing of the Heidenhain TNC155 on the Internet."

"Wait, I found it."

"PLC motherboard point diagram."

"Wait a minute...... Got it. ”

"Show me."

Just as Ye Ming was looking at the motherboard, Ita also found the drawings through the Internet, and then she began to generate pictures in Ye Ming's mind.

With the picture in place, Ye Ming picked up the multimeter and began to test the point.

At this moment, Ita's voice rang out on its own.

"Ye Ming."

"What's the matter?"

"If it's a test circuit, you can let me try it."

Hearing this, Ye Ming was a little surprised: "You can only feedback signals through electrodes...... How to try? And can you make it better than a multimeter? ”

Ita wasn't angry at all, at least not at all.

"I'm more sensitive than a multimeter."

……

Although Ye Qigang is a good lathe worker, he is hindered by his cultural level...... His circuit is really limited to repairing a plug-in board fan and the like, and when it comes to circuits like motherboards, then he doesn't know anything about it.

Therefore, when he saw Ye Ming put down the motherboard and said that he wanted to get himself a tool, he lost interest in observing and went to prepare dinner for his son instead.

On the contrary, Uncle Zhu next door was watching with great interest until his wife made two phone calls and called him home.

Without interference, Ye Ming carefully designed a plan to use Ita as a "multimeter".

According to Ita's description, she is "sensitive" because she can sense the slightest changes in current and voltage - if Ye Ming is bold enough to do an invasive brain-computer level, then she can even feel changes at the single electron level.

Such sensitivity...... It is indeed enough to make Ye Ming's eyes red.

But it's easy to say, it's easy to implement......

It is simple, too.

Ye Ming found the "scrapped" integrated electrode, and then connected five wires with enameled wire, and then connected the power supply part of the remaining Bluetooth headset, and then led out two more pins and it was done.

It's just that to be on the safe side, he added a resistor to the pinwire.

After doing all this, the time was exactly half past five, and the voice of my mother shouting for dinner also sounded at the same time.

"Okay Mom, right away—I'll start with the first pin?"

"Okay."

"Is there something wrong?"

"That's right, go ahead."

As the two continued to communicate in their minds, Ye Ming also quickly checked the entire circuit diagram according to the point diagram and Ita's guidance.

Let's be honest...... It's still quite time-consuming.

Because Ye Ming had already heard the sound of his mother walking outside the door.

"Fault found."

"Where?"

"Two chip resistors failed, and one memory chip failed."

……

At the dinner table, Ye Ming told his father where the fault of the motherboard was, and said that these are minor problems, just buy the corresponding model online, so as not to return to the factory to replace the motherboard.

Because this machine is a second-hand product that my father bought at the beginning, there is no after-sales service from the manufacturer, not to mention, once there is a motherboard-level problem, the price of the maintenance master is also extremely high.

Hearing his son say that he only needs to change a few keys to bring the machine back to life, the father is a little reserved, and the mother is quite ecstatic, thinking that her business will be open immediately.

But Ye Ming knew it from the chat with his father in the afternoon, especially Uncle Zhu next door......

The machining business is not good, which is the current environment.

Especially the small workshop at home, now it is holding on, that is, it is a hard loss.

But in any case, these thousands are saved, even if you have to dispose of the machine, you will not sell scrap iron.

After dinner, Ye Ming went to the factory to clean up the parts before returning to the workshop.

He needed to have a good talk with Ita.

"Ita, do you think there is a possibility that you can realize the management of clustered unmanned factories?"

"It's not possible, it's true." Ita's voice was a little calm and natural.
