Have you removed the metal strip which holds the small magnets? The metal strip in my unit required straightening so once straightened and screwed in the magnets were flush.
When you screw the housing back onto the fly wheel, does the housing sit flush against the flywheel?
The warp on the rotor isn’t as bad as mine but I’d check the metal strip first as the tolerances are tight within the unit while the quality of engineering/ specification could be better which makes for a challenging time.
I did remove the magnet strip. The metal backing strip is flat. 7/8 of the magnets are taller than the one though, and all stick up at the same height above the plastic lip of the housing. Another curious thing is that none of your magnets have the same dimples that this one does.
The magnets on the first image are clearly damaged. The only part that moves and comes physically close to the magnets is the fly wheel.
So I got to this point with my flux, resolving all the issues and the flux still made a slight rubbing noise when I rotated the flywheel. ( I had broken bits of magnet, magnetised to various parts within the unit and raised magnets scraping on the flywheel as well as a warped fly wheel)
My fly wheel was more warped than yours, however I am hoping you should be able to identify the offending part of the warped fly wheel. Just rotate until you hear the scraping noise and you’ll soon locate the area and which side it catches. Check yours but my fly wheel is much closer to the metal strip and mounted magnets than it is to the yellow magnets on the opposite side of the fly wheel .
The fly wheel is a delicate piece of metal and requires only a slight tap with a rubber mallet to straighten. At this point I was out of ideas and used a mallet out of frustration, however it worked.
Just wanted to follow up on this, we got the trainer sorted out and now it appears to work. It did have some trouble with the signal dropping out over Bluetooth, so we got an ANT+ stick with the extended cable and now it works fine (on Zwift). Time will tell how it performs, but for $112.50, it was worth the gamble. If it works for a year or more I’ll be pretty pleased with myself. I can understand why someone returned it at full price though, given that it had the scraping and may have had signal issues. I’d want that to work right out of the box if I paid $800+.
Hi all, I have the same issue creep up after the warranty period is over. Tacx support was super unhelpful. They told me there is nothing they can do and I had to get a new one. At least they give me a 50% discount but I will switch to Wahoo instead.
Can some one help me, the mag strip had one long screw that bent it. Whilst it was my fault I did check before putting screws in. However on removing the case to see what had happened 7 of my magnets FELL out, the glue had become crispy and they detached. Can anyone give me the POLE order of the magnets as I only have ONE that is original and correct. I have determined the pole of the 3rd magnet using a magnetic compass as N. I assume they are arranged [N]-[S]-[N*]-[S]-[N]-[S]-[N]-[S]. (from top) The only correct one I have is the N*. if you have a trainer disassembled please let me know your magnet order (use a secondary magnet to check or magnetic compass (like poles repell so North pole on compass will move away from north pole on magnet)). The correct magnet is third one from top, if the trainer was standing on the floor, below 2nd screw, going anti clockwise toward the rear leg.
Thinking from engineering side:
As resistance in Flux is based on eddy current brake (adjusted with electromagnets) good magnet field is key thing for operation. Most efficient magnetic field is result of short magnet path length.
I don’t think there is sense to arrange magnets in other order than N-S-N-S…
If magnets were arranged (as extreme case) N-N-N-N-S-S-S-S, that would need hefty iron to transfer magnetic field from most opposite magnets in use.
