I just took my Gen7 apart for the first time (Ive always been afraid of breaking it) and I was stoked to realize how simple it is to swap out the hard and soft clips. However, after trying to change back to the softer ( "O" shaped) clip, I noticed the machine made a different (almost a stuttering?) whirring noise, opposed to the typical cleaner whirring i was used to.

I watched the machine as it ran, and as the clip moved back and forth, the bearing itself seemed to be going up and down as well. is there something stupid i overlooked when reassembling the softer clip?

I switched back to the harder clips for now, and it's much quieter than I'm used to. As much as I'm liking it, I'm wondering if my voltages should adjust accordingly while tattooing with the new clip? I would imagine the voltage should come down, but I would just some assurance, rather than waiting for newer tattoos to come back healed.

Hopefully I'm making enough sense to be helped here. I appreciate anyone's help. Thanks much,
Matt
