sorry, you can example for me ?

[James Newton]

Just to be clear, the drivers that rinthesun received are NOT from Luc or I. Had he ordered from us, the errors he notes would not have been there, and the drive would work.

I could be wrong, but isn't this the calculation of your maximum lift:

1kg ~= 35oz so 175oz/in = 5kg/in

8cm shaft = 3.15 inch

Max lift = 5/3.15 = 1.59kg

Edit: oh, are you trying to lift 1kg or 10kg? You mention both values.
I think even 1kg will be iffy to control as the quoted torque is peak torque. The actual torque varies over the step(?).

Hi. Can you help me reduce noise on TB6600HQ driver?
I create driver by datasheet schematics, but when drive in idle it makes too much noise in some positions (use 1/8 step). Is any way to reduce this noise from drive?

Check the OSC frecuency (pin23)

Oscillation frequency fOSC WITH External resistance Rosc = 51 kΩ
Min 2.8 MHz
Typ. 4 MHz
Max 5.2 MHz

In a properly done circuit, the 6600 is silent at idle. If it isn't the most likely causes are
-using wire wound current sense resistors. Replace them with surface mount chip resistors.
-improper layout. I will comment if you post a photo of your board.

Please I'm really struggling with the TB6600 , can any one help me on this thread :

The Shapeoko Forum ? View topic - PnP Proximity Sensor with the TB6600 Controller

I'm testing with tb6600 driver DIY, because TB6600 is fixed decay mode 40% so stepper motor emits sounds. How do I fix this ?
Please help me.

This is a chopper driver -- I think these always make noisy steppers.

[James Newton]

A certain amount of noise is expected when using a chopper driver, but the 6600 is especially loud as far as I can tell... the TB6064AH is much quieter. The Linistepper is very quiet if that is a hard requirement for you. Some research places use it to position sensitive sensor probes, because if they use choppers, the EMF and vibration from the motors swamps the signal they are trying to pick up.

Very interesting, but I do not have any experience with it.
