Not really sure what you are meaning, it could either be backlash or missing steps. However as you say you have to re-zero then it sounds more like missed steps.

I put 2*3.5 vinyl rail to route pkt holes the more holes I route the more my hole are routed to the. Right of center whatever my holes are off my home is off the same amount and it is consistent. Y axis only to the right tuned motor different settings. And recalibrated!

Well I am not really clear on what you are trying to explain but if I understand it does sound like you are losing steps. Try increasing the pulse width to 10 and reducing your acceleration and velocity by 50% and see if that helps.
