Big Foot Auto Leveling Issue Page 1 (From TapaTalk Forum)

I was having similar problems and had updated to the .b version of the sensor without much success. After talking to Rick @ June, he stated that they had another upgrade to the .c version of the sensor. After I installed and reprogrammed that sensor, I have had no more problems. As was stated above, the guys at Quadra have been great to work with.

Hopefully, you get a good solution.

Thanks for the input. I think the situation with the rear jack in the case this weekend was the fact that the nose was so far down so the rear jack simply did not touch the ground. I have never had any issues with the rear jacks on either the Cameo or the LS.
I will definitely keep this in mind for the future. Phillip

I realized that it was the worst when there was rough road prior to entering my destination. The sensor gets shaken and takes a while to settle. Was that the case at your last stop?

Hopefully, you get a good solution.

My issue has happened twice – once prior before the new sensor and then once after about 3 trips with the new sensor. The first time it happened it was after going over a bridge in the area that has a series of awful dips in it. The dips created a series of full travel in the air bag travel of the Trailer Saver hitch. I didn’t hit anything that extreme on the way to my destination this time.
If the Big Foot is that sensitive to motion, then I can imagine I’ll have this issue often with the air hitch. Phillip

The more “stuff” that goes on these coaches, the more “stuff” there is to fail.

The other thing is that you shouldn’t have to disconnect the power for the system to work right. Either there is some flaw in the system or something else is going on. I have the “C” sensor on mine and the last time I used my 36FW it worked fine…In hibernation for the winter right now…I did have the same issue with the leveling until I installed the “C” unit from the “A” unit……Rich

I did mention to him about a later model/update over what I was sent a few months ago. He said that there wasn’t one. I don’t know if I have the “C” sensor or not but will look late this week. If in fact I do not have that model I will call back and discuss this as an option. Would be nice for it to just work every time without any additional steps. Thank, Phillip

If unplugging works, a kill switch should work equally well. Neither should be considered more than an interim solution until mfg can find out what is really going on.

The fact that it worked at one point after upgrade, then stopped working every time you use it suggests that the brain has lost the stored calibration memory. If it intermittently levels and at other times does not suggest such memory loss. In the first situation, the recommended un plus, wait, plug back in, recalibrate, a d keep unplugged when traveling makes sense. If the latter, simply unplugging when traveling should be all that is needed, i.e., no recalibration because it is still in memory.

Calibration does a few things, but primarily compensates fir a leak than perfectly mounted level sensor. That sensor mount “level-ness” is a function of how level the housing is mounted but also how level the sensor is mounted within the circuit board.

Could it be that those few that have the same troubled have mountings that are far from level, and this require extreme calibration values, and those extremes are overtaxed by residual motion from recent dips?

Maybe that is some of the logic behind ensuring that you are in a nose high position before initiating auto level. If that us the case, you might try putting the 5er into a sharper nose high position than you usually do, especially after a few dips.

May not be worth the extra experiments, but I am sure that Bigfoot would appreciate your trouble shooting.
