This is what I was trying to accomplish when the machine started not seeing the door closed

I mounted the stacker assembly from the WBA Cash Can to the back of the WBA chassis so it would be positioned properly (in same place that the cash can places it)
So it would engage the gears properly and function.
I used 3M 465 tape to attach the stacker to the back of the inner chassis.

i don't quite understand are you are getting a billvalidator stacker open and are trying to rig it up to work?  cause if u are getting a door open b error it is just the micro switch on the bill door just splice the wires

I do not want the can in the machine.

I can open the door to access the cash can and remove the bills or tickets without pulling the can, since there is no can in the machine.

In fact I can re-insert a Benjamin about as fast as the BV accepts it.

with cash cans being difficult to find it would be nice to completely eliminate the cash can.  Anyone know how to wire switches to remove cash cans?

I saw a video where the front of the cash can was cut off and the person just kept taking the bill and feeding it back through. Freeplay modules or other "electronic solutions" would eliminate the cash can completely. Or just get the plastic one

The WBA and UBA do not use switches (well not physical ones)
They are optical sensors that plastic fingers block
One that senses the cash can and the other one detects position of the stacker in the cash can.

Foster Your almost right.  All you have to do is remove the two springs and the the lower bill plate. Cut the front out of the bill box and your done.  I have all the equipment to cut a box but I never have. I would caution anyone that does, not to remove the door on the bill box,as  it would set to low and the optics will not see it.

I might as well toss in my tip of the day. Next time you have your bill box out, I use a large screw driver and smack the outer edge of the box where the door closes ( I use the screw driver handle ) If you ding the lip to much, just use the other end of that same swrew driver and bend the lip out a little bit.  NO more tape or locks needed to hold the door closed.

As Foster said, they are optics.  You can just block the one that senses the can, but the one that senses the position of the stacker has to go on and off at the right times, and won't work with it constantly blocked.

Foster, do you have pics of your set up?  It sounds like a great way to set up a home game!  :3- :89-

Only picture I can take.

I had to switch the double sided tape to 3M VHB double sided tape for two reasons:
1 move the stacker away from the back of the chassis the thickness of the back of cash can.
2 the 465 I guess was not made for metal to metal/plastic attachment.

No I will not use any type of epoxy or other adhesive I may need to remove the chassis and stacker when UBA come down in price.

I like the idea of just cutting off the front of the can. It may be a little more work,, but would pretty fool proof.

I thought about doing that.
I like way I did it because if I decide I want a cash can in the machine I just remove the stacker from the back of the inner chassis clean off the adhesive from the transport and the back of chassis
insert transport back into can and insert cash can back into machine.

as touchy as those things can be i wouldn't think holding it in with tape would be very reliable

VHB is Very High Bond.
It has not moved since using the VHB.
It is considered permanent adhesive.

This looks like a heck of an idea to try :3- I've got a couple extra cash cans so I might try butchering one for a conversion. I also hate having to pull the can out all the time to add credits. Ten dollar token values help a bit though :89-

You can remove the stacker from the can on the WBA very easily
Remove the can from the machine
All you have to do is remove 2 screws that are visible when you look at the stacker with the cash can door open.
Their might be one screw from the outside of the can into stacker on the back (opposite of the handle)
once you remove the screws push the stacker assembly up through the top (the side the bills enter)

Another reason I used the VHB because it was approximately the thickness of the cash can metal.
 

Now we just need to figure out how to switch the software to japanese yen, their money is cheaper to buy than tokens :97-

Hey Foster, If you look on the back of the stacker their is a screw hole that lines up with the frame. I pulled the whole assembly out and put a small screw to hold the stacker in place and then put it back in place and use the screw on the side to hold it all in. That's a great idea you had now I open the belly door and open the cash box door and just keep cycling the money through works  great with 180 credit machine.

did see the small screw hole in the back of the stacker but I didnt think to see if lined up with the small holes in the chassis that makes it even more secure

What sensor stops the motors and gears after the bill is "stacked"?
I'd like to make a chute so the bill comes back OUT of the machine with the belly door closed.... :208-

There are 2 sensors that detect the presence of the stacker assembly and stacker position (retracted or extended)
On the 2 moters and associated gear sets in the transport that drive the stacker and the pinch rollers at the entrance to the stacker are rotation sensors that operate similar to reel optics

I think for details of how those rotation sensors work we may have to get Op-Bell to chime in and give an explanation.

There are 2 sets of optics on the back of the transport that are broken or not by 2 flags attached to the chassis.  One flag breaks it's corresponding optic when a can is in place (the one on the right from the front of the machine).  The other breaks its optic when the stacker in the can is in home position.  That's the one that can't be permanently blocked, or the BV thinks there is something jamming the stacker and preventing it from cycling. It's also the one that tells the BV that the stacker is back in place after stacking.  :186-

All those 2 optics can tell the can is there and the stacker is in home position but not where the stacker is out of home position.
Those rotation sensors I mentioned are most likely used to determine stacker position and also keep the roller and belts from trying to roll bill into the cash can door
That stacker motor via gear reduction can apply some serious pressure on the stacker plate.
It tried to push my hand pretty hard.

Ah, I get what you mean by rotational sensors now.  Those are mounted on the motors to sense motor speed.  One does indeed tell the BV that the stacker is (or should be) moving, and approximately how far.  The other tells the BV how fast the bill should be moving past the optical and magnetic sensors, to properly read the bill.

Those sensors don't have to be "fooled" without a can in there, since they don't read the condition of the can (stacker).

I tried blocking those sensors and all I got was that the stacker was full error and the machine stopped so that's when I saw the screw hole on the back and screwed it to the frame and it works great I going to do this to all of my machines.

Can you show us a little pictorial on how this mod is done cartman?
It would be neat to see... :89-

Ok here are some pictures. thanks to Foster for the idea

Once you mount the stacker in housing put the assy. back in and use the screw on the side to hold it in the machine then jumper the the cash box and belly micro and you can open the belly door and cash box door and keep putting the same bill in over and over until you get tired.
