Yet, another Star Wars Post... Need help

[H4CK3R]

First off I did search, and maybe not enough..... But

I have a Star Wars cab, with Yoke, connected thur a A-pac.  After calibrating the "ultramarc game controller"  It seems the Y axis is really sensitive.  It jumps all over the place.

at Dead Center,  X =   247    Y = 2161
at Left Up,,        X = 2123    Y = -770 to -870  Keeps jumping
at Right Down,    X = -1920    Y = 2175

Seems the Y is way off...  at center its at 2161 to Down its at 2175.  Only 14 points off...  Thus is why its sooo jumpy in the game.  is there anyway to over ride the dead center point withen the the calibration?

What am I missing here?

Figured it out... seems the POT is going out...  I was looking at the new SW yokes, and he sells the pots, tho i am not sure what ones to get... the 5k or the 120k?  what would be better?

5K replaces what is in there. The 120K is if you were to hack the yoke to connect to a PC joystick port.

[H4CK3R]

Replaced the POT... Still the same issue.

dead center Y is at 2170 and at full up its at 2176.   Only 6 degree's off...

Just weird that its jumps really fast at the very bottom and top, but not steady in the middle.  is there a A-pac Config app?  Or a way to over ride the data settigns so that it get a full flowing motion for the y axis?

Take the pot out of the yoke and twist it with your hands to see what kind of numbers you get. Narrow the problem to a defective pot, an incorrect installation, a problem with the gears, or a PEBKAC error.

[Havok]

a PEBKAC error.

LOL -I haven't used that one in a while!

Also, try adjusting the analog sensitivity in Mame to see if you can compensate.

I have 2 extra pots, wired them both up, took out all other inputs to the A-pac, and just testing the Y axis.   Doesnt matter what pot I use, I can not get it to " Center" at 0, and have full motion up and down before it hits the limitor.

I thought that when you re calibrate the A-pac  ( listed at a Untramarc game controller) in Win 7, that it would take the readings, and auto center in and give the calibration at a dead center 0.

It does not.

If I adjust the clogs in the oppiste direction, IE -18xx , it still centers the Y axis at 2160 ish, with 2175 being the high end.  I have revered the wires, while keeping the gnd to gnd. and still same results.  

There is alot of free play going the opposite direstion,    I can center the Y axis at 2166, and hit a low at 2100, but still have a high of 2176.

So in a nut shell.....

it seems that at -1800 to 2100 its a fast moving Pot, then once it hits 2160 ish It starts to crawl.

Idealy, like the X axis it would center somewhere around 0, and then hit a - 1800 and a high of +1800.

I have already hooked the A-pac Y axis to the X Pot, and its getting the same results as if I just hooked it to the other pots.  And that leaves me to believe that this is a software issue?

I have searched Ultramarcs website and I don't see any software for the A-pac, it works as a plug and play.

EDit.  Going to see if switching it to the player 2 side makes a difference.

[H4CK3R]

OK after further testing this si what I came up with.....


BAD A-Pac.....

I tried player two side if the Y axis with two differnt Pots,  Both would only read a + reading...

I then switched the the Y axis Pot to the X axis slot on the A-pac...  Works perfect.   Dead center at 0, -1800, +1800 ish. 

Leaves me to believe either its a bad A-pac or Driver...   Deleted the driver and pluged USB into a differnt USB port on PC... loads up, and same results. 

=  Bad A-pac.

Will get hold of ultramarc and see if they can fix, or buy a new.... My entire weeked gone...  But on the bright side, at least I believe I have found the problem.

PS.  its only the y- axis doing this... Could i use the Player 1 up and down axis with player 2 up and down axis and have mame see it as both controls?  Just an idea...

[Havok]

Sure - you have 4 possible axis' with the A-Pac. Connect the two that work properly, and map them in Mame.

anyone know what angle the original yoke is mounted at?

I'm not sure if there are any plans anywhere, but I just took some quick measurements. Hope this helps.

[Chunce DeLeone]

looks about 45 degrees, it lines up with the side of the cab

Yes, if you "do the math" it turns out it is 45 degrees from vertical.

thks dude,
