4th Axis

A:
Yes. Please note that you need to buy a stepper drive board for the 4th-axis when you buy a 4th-axis.

When you receve them, you need to install the 4th stepper drive board into the control box. The micro switch of the stepper driver board has been set, please do not change it. For the wiring of the stepper driver board, please refer to the XYZ driver board.

A:
Yes. Please note that H50-TB65S -4th-axis does not have the 4-jaw chunk.

A:
Stepping motor 1.8 degrees, it needs 200 pulses to make a circle (200*1.8=360 degrees),

Now the default setting of this machine's stepper driver is 8 subdivisions,

That is, 200*8=1600 pulses are needed for the stepper motor to make one revolution;

AH60-XX80M-10 A-axis reduction ratio is 10:1,

Then the stepper motor needs 1600*10=16000 pulses before the chuck can make one revolution.

That is, 16000/360=44.444 pulses are required for the chuck to rotate 1 degree.

You can change the drive segment according to your needs,
For example, when the A-axis drive is set to 32 subdivisions: 200×32×10÷360=177.78

A:
Step 1 , look at the following calculation:

Stepping motor 1.8 degrees, it needs 200 pulses to make a circle (200*1.8=360 degrees),

Now the default setting of the X8-2200EPL machine's stepper driver is 16 subdivisions,

That is, 200*16=3200 pulses are needed for the stepper motor to make one revolution;

Because the A-axis reduction ratio is 10:1,

So the stepper motor needs 3200*10=32000 pulses before the chuck can make one revolution.

That is, 32000/360=88.889 pulses are required for the chuck to rotate 1 degree.

Step 2, see attached picture, set the value of No.38 to 88.889. （如果是H60-A轴， 设置为35.555）
