Belt Tightening / Tension HELP - Shapeoko XXL

Good morning,

I have had a lot of trouble finding good information on how much tension my X and Y belts should have. Can you please share how you measure your belt tightness to create the best results possible?

Thank you,
Brian

I wrote a bit up at http://www.shapeoko.com/forum/viewtopic.php?f=10&t=5948 and https://forum.shapeoko.com/viewtopic.php?f=37&t=6765&p=53075#p53075 but the former is obsoleted by the new belt anchors.

The steel-core belts seem easier to me to tension than fiberglass (I suspect that was a leading reason for the change) and https://docs.carbide3d.com/assembly/shapeoko/xxl/step-5-belting should suffice.

If it doesn’t let us know what you’ve tried to support@carbide3d.com and we’ll do our best to help.

Thank you, Julien.

Should it be this tight when the X-Axis is all the way to the rear, or right in the center of the Y-Axis?

I didn’t think mine were too tight, but this happened:

Any idea what may have caused this to happen to my Y2 and X belts?

Gantry all the way to the rear, but my video is on a SO3, on a XXL machine it’s probably not quite as tight (longer belts).

I remember seeing another post recently with a stretched steel core belt exactly like your pic, but I can’t find it right now nor do I remember what the cause turned out to be. Probably support can help you out
