So you have your belts on your shapeoko and you want to tension them the same.
There is an easy way and has work flawless for me.
Upload in your mobile phone any guitar tuning application. Usually they have a mode that shows the frequency of the string.
Move the gantry at one end and play the music. When the tension is the same in both belts they will show the same frequency in the tuner.
Mine are tuned at 110 Hz that is very close to the "a" note.
Hope it helps.

An easy way to adjust both y belts with the same tension.
Re: An easy way to adjust both y belts with the same tension
That's smart. I was doing it by ear before.
Of course, this is harder for Shapeoko users, who need to hold and turn the Allen key with one hand, push on it to tighten the belt with a second hand, and pluck it with a third. They don't have our neat belt tensioners.

Hmm......I wonder if you can use one of those guitar tuners that clip to the guitar's headstock and clip it to your endplate?

I have one and I will try it tomorrow.

You can do one better with an app made for this, and get tension numbers for all your belts to be the same even for different-length spans. I checked it out and it's pretty simple: https://play.google.com/store/apps/deta ... n2Go&hl=en
It doesn't have GT2, but .25" MXL is pretty close.
