Hi,

I have problem with Mach3 that before that just run great.
I have my 'Spindle speed averaging' not saved even I have to restart Mach3. The rest just saved like it should. How to fix this?
And also if I don't select 'Spindle speed averaging', why the RPM reading not showed up in Spindle DRO/display? But I can get the spindle running through all speed. 

Can someone give me the way out?

Thanks

For a lathe or mill?

You should be able to save a configuration. So select the spindle speed averaging ,apply, click ok.
You need to turn the spindle on in order to have rpm show when it's running and properly configured in Mach.

It's for mill.

I did that too, but it won't save the setting. Even just click Reset it revert back unchecked.
I have tried reinstall to version 62, the rpm also won't showed up.

EDIT: Also got info in another thread that maybe the setting file is read only, but none of them checked as read only file.

Try changing the setting as I replied. Then go up to the tab and save settings. Then exit Mach and come back in. See if it now changed.

Not sure for the mill but for the lathe spindle speed averaging just takes initial and last rpm and averages them to base the next feed rate for threading.
So practically speaking may not that important for the mill.

Hi Rich,

I have tried it but it still revert back to default (uncheck) after restarting Mach3.
I'm just curious why before the rpm showed up and now is missing.

We get a lot "it worked before and now it dose not" and the answer is:
What changes did you do in configuration or to the hardware from when it worked before.

Try an xml file that worked before. A backup to a changed xml is created in the Mach3/xmlbackups directory.
Copy one over to the Mach3 directory and rename the extension from xm# to xml.

Actually, I was installing screensets before then the rpm gone. I have also made a new profile but didn't work, with cloned profile and fresh new profile. The default set didn't work either.

How to use xml backup in Mach3? I haven't been done that before.

Each time you change a profile a backup is automatically created and settings are saved in the xml file.
