Oh, I like his second method. That works well for belts that are too loose to begin with and we just have to tighten.  

But the first method tells us exactly how much we are going to need to tighten the belts. It was one adjustment and done for me.

Mainly because I had already tightened the belts the first way using the older string plucking technique. So using this tool I was just tightening a touch more to allow for the stretching of the belts since my initial setting.

When the belts are properly tensioned, run the wizard again and just before the part where it vibrates the belts (the head is locked into position), pluck the top and bottom belts across the gantry with your finger. Remember that sound. I can retention my belts (from being completely slack) to be almost spot-on just by ear. Or at minimum get them within range.

I have a video, but can't seem to get this to attach to the post.

Lol I am still do not understand how this works. I get the gyst of it, but one thing is guessing and the other one is knowing you are doing it right. 

I gave up and went with the old method of stringing the belt with extruder in the right corner. Seems a lot easier to me this way. 

That said, since the new FW, the machine does 8 BANGS rather than the old 4 I use to get. I did the belts just like I always do so I did not change that, the belts are 98 and 92 respectively. Another thing, after tuning the belt this way (old method) I then compare to the new functionality and the belt barely move, they do so however a little bit and have a bit of a 'wave', but minimal. I gave up trying to understand this method, the instructions are just not clear so I will go back to it once they become a little bit more straight forward.

Thanks

Alpha releases are really only meant for internal testing by Prusa's developers. Or at least that's how it's supposed to be. They are generally not released to the public. The fact they release to the public so early is unusual.  Next are the beta releases. Generally these are the ones given to the public for early testing and are supposed to be a lot more stable. No new features added, just bug fixes. Then the release candidates are made available in which all the documentation and other instructions will be made available. Generally these have (or should have) very minor fixes like language translation errors, typos etc or any serious bug fixes that didn't get caught in the beta releases. 

Again, my advice is to wait until the beta release is available. There should hopefully be better documentation by then. Remember the alpha releases are supposed to be unstable, incomplete and will break. That's just how it is. 

I dont understand why you are so impatient ?

When the release is ready to start, the dokumentation will be ready too.... 🤔

If you want the belt to absolutely run synce with the strobe, you would need to adjust the belt a bit. Sort of same when tuning a guitar. 

Not sure if it makes any difference though, i.e. it doesn't need to be that accurate. You could be off by a few hertz and I suspect the results (print) would be the same.
