Hi Pierre,

You aren’t explaining where you are “Jogging”?

Configure, test, and tune your axes in KMotion.exe before running Mach3 or KMotion CNC.

What is your X axis wired to?

Hello
I'm having a problem with the servo motors in the mach3.
The servo motor refuses to respond to buttons.
All three axes work in KMotioncnc.
Coordinates are updated in mach 3 when moving from KMotion.
I'm attaching the initialization file and photos from KMotion.

You might try setting the ports and pins to 0 as described here.

Are the axes enabled in the KMotion Axis Screen?

Is Mach3 out of reset?

Should I set all three axes to 0?

I won't be able to see how the axes are displayed until Monday.

When I press the reset button on the Mac 3, it says "Dynamotion OK," and the coordinates in KMotion turn green.

Please re-Post your initialization C Program and Mach3 Profile and we can look at them to see if they are now correct. Make sure you post the Initialization C program Mach3 is configured to use.

I can't see in the video what you are doing and what is happening. Its better if you explain.

You should be using the same Initialization Program for KMotionCNC and Mach3. If it works for KMotionCNC it should work for Mach3.

When you Initialize in Mach3 and Jog do the Mach3 DRO's change?

Do the Destinations change in the KMotion Axis Screen?

What does the KMotion Axis Screen the show how the axes are configured.

You show an Axis Screen configured as Step/Dir but it isn't clear that is after Initializing in KMotionCNC or Mach3.
