I recently outfit myself with an Atlas arm, my last few arms were G40 and G50x
First off, the arm is amazing, but we already know that.
However I am experiencing the result of something that may be too good about the arm:
The elbow has so little friction that it is actually laterally bouncing against the lower arm, which is translating into tiny "taps" on the sled with almost every step.
It is as if the inertia of the upper arm is carrying it away from me, then my foot lands, and the lower arm catches up, thus the tap. This is somewhat overexplaining it, but its how I imagine it. I am trying to get a video of it, but its a little hard while carrying the sled, but Ill update later when Ive devised somethin.
The post is loosened so that the Atlas "wrist" can move freely (I have also tightened it with no change in elbow performance)
The sled weighs in close to 39 pounds and I am using two grey canisters appropropriately tightened for the load.
The G-series arms have great elbows, but under load there was a bit more friction, so it took some effort to articulate the elbow, thus it wasnt bouncing.
Is this a result of my operating, stepping, looseness in the arm...? Any information is helpful
Have a good one
