Voron 0 formbot - X Axis after belts installation

[shkop]

After installing the belts, the X axis is not "balanced". There is some offset on the left side when it's reaching the rear... I'm attaching a video. I don't know if it's acceptable or possible implications.
The belts are stretched equally. They are identical in length and have the same tails. I also was very strict with the frame build. 
I have some troubles measuring the frequency as Pano tuner doesn't work well on my smartphone. It seems to not refresh the readings and I get inconsistent readings. The belts look stretched well to me, but I know it has to be measured. If you know a good frequency detector that might work better, please tell me.

I'm kind of stuck...

Cannot see the video but it sounds like you need to rack the gantry. See this video form Nero3D:

After that, tension the belts. Use this handy tool to tension the belts rather than the Pano Tuner:

Here is another of the same.

See previous post.

Honestly, for my V0.2 I used the Nero method: pluck the belts and tweak on the tension knobs until I hit "eh, feels about right." The first couple of test prints after basic tuning & input shaping look great, so I'm content. I couldn't get a phone instrument tuner app to give me anything like useful readings, and I tried several.

@mvdveer What is the optimal place the needle has to be with that gauge? I have it between 2 and 3. Is it ok?

I calibrated my calibration tool with the music wire to1.8 and then set the printer belt tension on the printers to 2.2.

I would probably lean closer to 2 than 3. As long as the belts are equally tensioned, you should be ok.
