So I updated to 4.1 and whatever firmware it came with. I’m noticing this new behavior. When I jog the machine a small amount like 1/4” it overshoots and then pulls back into position. Like a pulse. Possibly more concerning is it does this when I jogged the Z too. So I move the z down and the machine pulses sideways and back like an 1/8”. It appears to finish in the correct place but it’s very hard to move to a prefered home position on the material like this - both for the z home and when defining the lateral home position. Any ideas? Is this the new normal? Going to try to add video ---

Are you using it in horizontal or vertical orientation? It sounds to me like the tension in your belts might be a little too tight which is causing the motors to sort of fight themselves. What you are seeing is the feedback control system engaging and disengaging causing the machine to move a little bit. In vertical orientation you will pretty much always get a bit of that especially higher on the board where the upper belts are tighter. ---

It’s vertical! So it sounds sort of normal then? What about if it’s doing that same pulsing when I move the z? That’s actually the weirder one. But maybe it’s just adjusting tension as the z changes? ---

Whenever any axis is moving they all power up so it’s the same thing 😁
