I posted a few in the “Where do you park your 992” thread, but will drop a couple here. Just added the Swisstrax:

Ball park on the cost for the floor tile thingys.. my floor is coated but I have a lounge section this might me nice to have

A month or so ago, my swinging garage doors started opening too far and banging into each other. My doors are controlled by Franklin Autoswing openers, which are designed specifically for swinging doors like mine. The only problem is, virtually no garage door service companies near me are willing/capable of working on them. I had a couple "garage and gate' companies assure me they could work on them, only to make a quick exit once they saw them in person. So, out of options, I was finally able to dig in myself see if I could fix them. I'm posting this in part because there is virtually no information about these openers on the internet, other than the mfg.'s install instructions and related materials. Happy to report I got them fixed.

The openers have internal limit switches the stop the doors when fully opened and fully closed, which are triggered by adjustable cam lobes that rotate with the motor inside. The design of the limit switch cam lobes leaves a bit to be desired, as the design puts them at risk of spinning on the shaft and getting out of alignment -- exactly what happened to mine. See pics below....

To get the motor off the wall, I pulled circlip off the clevis pin and removed the pin to get the arm off the motor. Then removed the 4 m8 bolts holding the motor the mounting bracket. To get the top cover off the motor case, I removed the 4 tiny screws in the corners of the case (red arrows).




power-wires.jpg
With the circuit breakers turned off and motor unbolted with the top off, I removed the Green, White, and Black A/C power wires (be sure to take note of which color goes where -- they vary from side to side). The other wires can remain in place. With the power wires removed, I was able to take the motor to the bench to work on it.




limit-switch-test.jpg
First thing I did was take the cover off the two limit switches and confirmed they both worked. For each limit switch, when the red button is pressed, the switch should close -- giving you continuity between the 2 blades with the connectors installed.




limit-lobe.jpg The motor has these black plastic cams that rotate with the motor. When the cam gets to the limit switch, it closes the switch and stops the motor. There is an upper lobe and a lower lobe, one for stopping the door when it is fully closed and one for stopping the door where you want it to stop opening. These cams rotate on the motor shaft and can be tightened down in any location. It was clear that one of the cams had inadvertently spun on the shaft, despite the clamp-down screws, resulting in the door opening way too far (and banging into the door from the other bay).




cam-removed.jpg
This little cam ring slides over the lower lobe piece to create the upper lobe. What I did was open the door to the desired open location (with the arm attached) and then rotate the cam until it just clicked the limit switch. Then did same thing with the other cam with the door closed. Worked like a champ on the first try. The left and right motors rotate in opposite direction when opening and closing, so on one side the upper cam sets the door-open position, whereas on the other side the upper cam will set the door-closed position.

I'm too often amazed that manufacturers invest absolutely no effort into a thin film of silicone grease on the plastic wear parts like your limit cams. Scratches head where hair once grew....

The design is very un-Porsche-like. That outer cam ring can rotate 360 degrees, and there is no real mechanism to keep it from spinning (and going out of adjustment). Two screws/washers just press down on the thin edge of the collar from the top. I'm no mechanical engineer, but that ain't no way to lock a spinning collar in place. Surprise, it slipped.

Amazing diagnostics, disassembly skill, and repair. A lot of patience too. It's sad that supposed experts turn tail and run but I'm not surprised. I'm glad that the device was adjustable/repairable - so many components in today's "things" are basically unrepairable even by the most skilled. (I guess that's another reason to laud your 3-D printed parts skills!)

Tom, you lost me at “limit switches.” I guess you didn’t learn that stuff in law school?

Thanks. Honestly, I was pretty tempted to model and print those parts to eliminate their ability to spin, but I'm so behind on everything right now, I just wanted to get the doors working again. If it happens again, I'll come up with a better locking mechanism for those cams. I'm sure some of the pro garage guys could have figured it out if they tried, but they get scheduled for many (cookie cutter) door repairs a day, so when they see these odd-ball openers they have no interest in trying to figure them out (let alone hunt for parts that aren't stocked at the warehouse the visit daily). They'd rather move on to the next Chamberlain door they know they can fix in an hour or two with parts already in the back of their truck.

I only went to law school because I couldn't get into our Community College ASE Auto Tech program. True story.

More than they used to be, like most things these days! Ballpark is $5 / sf.

I have the “Pro” which is intended for parking / washing as they drain well. They have some other versions that might be better for a lounge area, like the “Smooth “ version. There are tons of articles and videos to study.
