Head-stabilisation - connect X-Y axis-tubes - Primo

Hello together,

i searched via google and also in the forum but didn’t find anybody who saw this problem:

To stabilize the X-Y axes especially the bend away from the head it would be easy to connect the 2 tubes with roller bearings.at the point where both tubes (near to the z-axis) are in 90° angle

sorry i’m quite new here.

I wanted to add the marking:

I mean especially this point (as marked).

Here it could be possible to connect these tubes to each other. So the distances between these 2 tubes are always the same.

The core does that, although it is a few inches away.

Once all the motors are engaged, I’m ot sure that squareness will be a problem. Have you seen flex there caused by the bit after the motors are engaged?
