Z-Wobble layer lines


#1

So I recently replaced my hotend for a new one and got a new thermocouples and heater since my hotend started oozing at the top. Now my prints have a z-wobble or something going on. When I compare my old prints they didn’t have any of these before.

I’ve gone thru and tightened all the belts and checked all the Hardware possible, leveled the bed, checked the flange mounts. I’m almost wondering if it’s a hardware firmware change or Z-suite change. Not sure what is going on anymore.
