Poor work G28

Hi Nikolay81:
According to your request, I have changed the implementation of G28 (O9028) in slib.nc, Unzip the attachment and reinstall slib.nc on the controller.

Also, the G53 command, which many like, works incorrectly with the Z axis. For example, G90 G53 Х0  ...

G28 instruction format: G28X_Y_Z_A_
Among them, X, Y, Z, A are the coordinates of the intermediate point (below the current workpiece coordinate system) when returning to the machine zero. After the command is executed, all controlled axes will be quickly positioned to the intermediate point and then from the intermediate point to the machine zero.
If you want to return an axis directly to the machine zero via the G28 command, such as the Z axis, use:
G91G28Z0

In the DDCSV system, G53 is not a machine coordinate system movement command. The slib.nc in the attachment expands the G153 command for you. By this command, the tool can be moved to the desired machine coordinate position.

Many thanks. G28 works correctly. G153, also works, but not quite right. In G53 you can set the sp ...

Attachment installation file supports G153 speed control

A simpler example.
Program:
G153 Z-2 F2000

I don't know how to describe this problem. I made some changes to the program according to my understanding. Let's see if it can achieve your intention.

Dear ytliu.
I will explain my situation.
I am the chief engineer of the company Aerotechservice ht ...

Hi,Nikolay81!
I basically understand your needs, I will try to design an example according to the process you said. In addition, the "-add the ability to play the audio signal from the g-code" that you mentioned is not very clear. Is it controlled by an IO?
