Is automatic re-calibration of the machine possible using multiple homing fiducials??

[Greg Toman]

Is it possible to use more than one homing fiducial and apply the same corrections to the entire machine, as is done with the fiducials on a pc board?

My machine uses belts, and occasionally I have had to re-calibrate the machine. It finds the single homing fiducial just fine, but probably due to the belts stretching over time, I occasionally have to  reset the pick location for most of my feeders.  This is time consuming. Is there already a way in OpenPnP to do this?

It seems like others who use belts must have encountered this same problem. I can see this drift  easily as I placed a second fiducial at the location where the head is parked. Over time the accuracy of the park location drifts, which is also reflected in the accuracy of pick locations from the feeders.

Thanks
