Stab Motor Problems

[TreDEE]

Hey guys I'm having some problems driving a Stab HH90 with a Dreambox 7020s. Ive setup the sat config and when I go to motor config I select gotoxx and enter my lat/long. Under mode I select "position" and then I select a sat to drive it to but it wont move. I can manually drive it east to west and set it back to "0" but it wont drive to any satellite I tell it to. Any ideas? Here is my setup

DM7020s
Fortec 80cm
Invacom QPH031
Stab HH90
RG6 Quad shield run of about 50 feet from dish to Dreambox
Diseqc 4x1 switch

If it has DiSEqC 1.2 or USALS use that to motor the dish. I would also remove the switch to see if thats the problem...

Well SatMex5 @ 116.8 is my southernmost sat. Any of you pros have any tips on the best way to peak it? Whats the strongest Transponder? Im going to try and peak that first as my ref point and hopefully everything else will fall in line. I'm tired of screwing around with Usals.
