Just a update with what I have done so far.
I dissassembled the original Openbuilds frame that I had completely and used the components for building custom coreXY 3D printer.
Decided to move more for the 3D printed parts.
So I made another all brand new coreXY type frame for the pick and place also. And designed and printed the new head and come strip feeders. Not sure about the about the accuracy of the new frame yet, although I am very pleased with the coreXY concept overall.
So here is the overview of the current system:
Feeders and board holders are held in place with small magnets under them.
Here is the fusion360 link for the head design:https://a360.co/2ZyjDni
