In that case the contents of the directory are those that were created by your stepconf run. You (presumably) have not actually extracted the zip file yet.

It should be very easy, you click the link on the web page, it askes if you want to open with Archive Manager, you say "yes" then extract the files into the config directory (over-writing the existing).

However, if you already have a V90.ini, then why not use that?

If your running 2.4.7 that is the most current version.

You can't edit a config you downloaded from the net with the Stepconf Wizard only a configuration generated by Stepconf Wizard... you will have to manually edit the ini file and change the sign of the Z axis and swap the X and Y axis outputs. If you feel overwhelmed by that task attach your ini file to a message and I will tell you what to change. Does this drive just use a parallel cable to attach from the PC to the driver board?

That's not strictly true in this case. The downloaded config includes the Stepconf data file.

However, I am not at all sure what config he is currently running. The config from probotix still included the nml line in the ini when I downloaded it yesterday, (though I got an acknowledgement from probotix last night for the updated config I sent them)

I suspect that Jerry is actually using the config that he created himself with Stepconf.

Updating / upgrading and saving my configuration to disc. Can I save to a thumb drive by copy and paste and what specific file please.

If you want to back-up a config, then you should copy the whole config directory and stepconf file for the config. In this case that would be the V90.stepconf file and the V90 directory where the V90.ini lives.

Am I correct to understand that since the NML_FILE = emc.nml was removed I have the most current version of EMC 2.4?

No, as that INI file line was removed during the transition from 2.3 to 2.4, so you could have any version of 2.4. The splash-screen at startup tells you the exact version.

Should I ignore if a wiindow pops up giving me the option to update or upgrade to another version of Ubuntu?

You should update most things when prompted (including Emc2/ LinuxCNC) but you must not take up the option to upgrade the _version_ of Ubuntu. You should take the update and security options though.

All examples work, but when I toggle the "x" axis, the "y" axis moves and when I toggle the "y" axis, the x axis moves /quote]
You can change that using Stepconf, or manually editing the HAL file, or swapping the wires to the stepper drives, or swapping which stepper drive the motors connect to. Any even number of swaps will leave things unchanged

Went thru the meun and selected apply. These settings were not retained when I restarted the program and the z axis was reversed again. Please advise. Thanks again[/quote]

That seems odd. I rather suspect that you have mutliple configs now, and you were not editing the config you thought you were editing.

What do you see in your ~/emc2/configs/ directory at the moment?

Ok, for the Z axis change the SCALE for axis 2 (the Z axis) from 4800.0 to -4800.0.

Attach your .hal file and I'll explain what to change in that to swap the X and Y axis.
