Spindle Calibration by Manually Editing the .xml
« on: May 28, 2011, 09:39:18 PM »
My mill does not send a tach signal back to the control computer but the spindle speed is visible on the motor controller.
Since I dont have a tach signal I cannot auto-calibrate the spindle.
I wish there was a way to manually enter the spindle speed vs PWM %.

I think it could probably be done in the mymill.xml file.

Does anyone have any experience with editing the xml to achieve this?

You might want to try playing with the pulley speeds.

I dont think its pulley speeds I need to change. Its the stored data when doing an auto-calibrate. I want to manually enter it into the xml. Or adjust whats already in there.

I don't think it's in the .xml

I think it's in the linearity.dat file/

Thanks. I just tried to open it but it is not an easily understood file.
Do you have any idea how i could edit it or understand it?

Nope. But if you delete it, a new one will be created.

That is interesting but not useful information.

I opened the Linearity.dat file in a hex editor and the structure is not easily visible....

Does anyone know how to accomplish a manual config?

I have thought about hooking a function generator up to an input pin and matching it to the displayed rpm.....
