when moving to the edges I noticed when I tuned the Z axis by 0.5mm that Maslow was swinging strangely.
As if the motor wanted to do some compensation when it was closer to the anchor.
it always happens on the morota, which is closest to the anchor, so it’s not on a specific one, but I do it all. I tested 4 corners. It doesn’t do it in the central position.
I’ll attach some videos via google photos
firmware version 1.12, index 1.12. Frame 4.4mx3.6m calibrated with a 9x9 grid to 2000x1000.
Retraction Force 1700
Calibration Force 1600
then I tuned the axis scale, about 4% on each and then drove to 1mm exactly.

have you set your Z distances? (Z offsets and/or spoilboard thickness/workpiece thickness)
The default Z offsets work if your anchors are at the height of the bottom of your sled, but if they are lower than that, it will throw off the calculations of the anchor point locations.
If you can raise the anchor points, that should reduce the downward pull on the arm as you get close to the anchor (make sure you adjust the Z heights as mentioned above)
I have noticed a similar effect. It only happens when you are jogging, not when it is running a job. I think it is to do with the pressure on the motors being released when the power goes off, and then when you jog it reapplies power causing the maslow to pull in the little bit of belt it had released. I think it is worse near the corners because the forces are uneven, making it more noticeable.
