On June 29th, Lee countermands previous orders to Ewell to advance on Harrisburg (after Jenkins' cavalry reached the shore of the Susquehanna River). He initially orders Johnson's Division to move towards Chambersburg, turning off to march through Fayetteville and cross the Blue Mountains to reach Cashtown. Ewell is ordered to send Rodes (around Carlisle) and Early (around York) to march towards Cashtown and Gettysburg. At the same time, Heth reached Cashtown with Pender and Anderson back towards Fayetteville and Longstreet further back around Chambersburg.
On June 30th, Heth probes towards Gettysburg while Pender and Anderson advance towards Cashtown. Longstreet begins his advance east from Chambersburg. Johnson ends his day around Scotland (about halfway between Shippensburg and Chambersburg), Rodes moves from Carlisle through modern York Springs and camps around Heidlersburg. Early marches through East Berlin and camps a few miles east of Heidlersburg. Hood and McLaws march from Chambersburg through Fayetteville to the base of South Mountain.
Clearly, Lee is concentrating his army in the vicinity of Cashtown and Gettysburg, leaving Chambersburg behind.
