Hi all. I went through the stepper calibration procedure in Mach3. That's the one where you choose to calibrate X or Y etc, and it asks you for how far you want to move. And then it asks you how much it actually moved.

Once that calibration is done, Mach3 stores the calibration data in a file, so that the calibration is automatically re-loaded into Mach3 every time Mach3 starts up, right?

May I ask what file to look for so that I can confirm that Mach3 has stored the calibration settings?

Eg. When I did a y-axis calibration, I chose to move 50mm. Then Mach3 asked how much it moved. So I entered 50.202mm. A number then popped up like 398.*********x

Does this 398.*********x value get stored in a file somewhere? If it does get stored, then may I ask which file it is, and whether the file is in a simple text format so that we can get a confirmation on the stored setting?

Thanks all! Apologies in advance for this rookie question!

Hi,
yes all that data is stored in the profile. Lower right of the Mach screen is the current profile name.
In the Mach3 folder there will be a file: <profile name>.xml.

If you use an XML reader you can inspect, theres a lot of data. Unless you know what you're looking for it may not
help.

Greatly appreciated Craig. Thanks very much for your time and help!

Go to motor tuning and look at the steps/unit.

Thanks very much as well ger21. I went there and can see the correct values there. Really appreciated.
