什么样的皮带和皮带轮？皮带轮上的齿数、皮带齿距等。您使用的是哪种微步进？ 通常在皮带驱动的机器上，您需要获得最小直径的皮带轮，并且您还希望微步进得足够高以获得每毫米的良好步进脉冲数。 |

每毫米有 5 步？ |

Oh thank god! I will work on it tomorrow and keep you guys updated! |

UPDATE : Still not solved. So i linked the pins on the CNC shield like this https://cdn.instructables.com/FFR/W25T/IWQV78FT/FFRW25TIWQV78FT.LARGE.jpg?auto=webp&crop=3:2 I did the 16th microsteps, but my motors are still acting exactly the same, they still need 200 steps for a revolution. Only 1 motor is 1/4 for a reason i ignore .. even if all of them are wired the same way.. Question : should i solder the cables in there ? |

That’s what i did. So i set it back to 5steps/mm, then the machine starts moving slow like hell ! |
|
So change your feed rate and Max axis rate
|
How do you ‘move it 200 steps’? |
|
I moved my machine 1mm ( means 200 steps ) and it actually moved 40mm. So i set the grbl to 5steps/mm. And now that i am looking at it, thr GRBL settings are in steps and mm, means if you go from 200 steps/mm to 5steps/mm and you still want to go with the same speed, you need to go give that max rate a 40x multiplier. It would have been much simpler if everything was in steps i think. Steps/mm , steps/min and steps/sec2 .. because now if you change setting you need to take out thr calculator and figure out everything again .. I will check this and tell you what’s up. |
|
Problem solved. It was me, i thought setting up the grbl needed only changing the steps/mm, but once you touch those all your settings are broken, especially when going from 200 to 5 .. |

|
What did you do how did you settings end up looking. I have the same problem |
|
Some of the poles were not wired properly, i just had to solder them.

@fatmisami……..I am using Arduino Uno + CNC Shield v3, 2 nema 17 motors with 2 A4988 drivers. My X axis is attached with M8 x 1.25 Pitch rod & y axis with GT2 timing pulley & 2 mm pitch belt. I’ve tried 8th & 16th microstepping. But I can’t sync the X & Y axis at same feed rate. The y axis with belt has same problem as yours moving very slow. please help me with this. |
|
You have to calibrate the steps/mm for each axis first. Then the speeds will be the same.
|
|
I haven’t done anything with that CNC machine for over a year now. |

我也有同样的问题。只需从 Arduino 上取下防护罩并将微步进针焊接到 1/16，然后将每毫米的旧步数乘以 16。它应该可以工作。有时使用跳线连接微步进引脚不起作用。 |

你是做什么的，你是怎么设置的。我也有同样的问题 |
我自己做了一台数控机床。
电子设备：Arduino Uno + CNC Shield v3 + 4 A4988 移动 4 NEMA17。
NEMA 17 正在用皮带和滑轮移动我的轴。测量时，每毫米为 5 步。
有了 $100=250 ，我的马达工作得很好。但是一旦将其设置为 $100=5 ，机器就会变得非常慢！电机在振动，一切都表现得很奇怪。
任何线索？
