Chris,
	Had the same problem with bubbles in the SL5170.
	Try this it works well.

	(NS 3;P1 4;G1 100;P2 12;G2 4000;P3 5;G3 140;PD 4;ZW 25;ZV .2;ZA .2)

	The slow movement of the wiper on the second sweep, with the deep dip
	pops the bubbles as they are formed, the longer you use this method
	the better it gets.

Dave,
	You are right in the 3D/sys menu system it will only let you put in 999.
	If you go out to dos and edit the ".r" file you can make it anything you
	like. 
	If you find this works for you (like I did) then you can edit the machine.prm
	file on the computer that you "merge" your files on and put this entire line in
	(NS 3;P1 4;G1 100;P2 12;G2 4000;P3 5;G3 140;PD 4;ZW 25;ZV .2;ZA .2)
	that way every time you merge files this will be the default.
	Below is a copy of a ".r" file and a copy of a machine.prm file.

	Sorry for the confussion.
						Randy
