I have a linear motor that travel two directions along the x - axis ( Back and forth). a positive voltage drives it to the right, a negative voltage drives to the left.

Is there a way in the 3.3v realm to produce a square wave that goes a full + 3.3V pass through zero and on to a - 3.3V?

Thanks in advance for any advice.

Apply the pulse to a pulse transformer that has a center tapped secondary and you will get the +_ pulse, measured to the center tap, on the secondary winding.

Easy to do with a bipolar supply op amp.

But, I seriously doubt that is what the OP really needs. A link to this mystery linear motor would be far more helpful than our guesses at answering what appears to be an obvious x-y problem
