I've been having some issues with chain rub on the front derailleur. I have a 3x8 bike, on the largest chainring I noticed some side to side motion on the chain when trying to set it up after watching the Park Tool video. The Crankset is an unknown model ProWheel 48-38-28T on an unknown model square bottom bracket.

When setting high and low limits to try and get about 1mm of clearance between the chain and the FD cage I noticed that depending on the crank rotation this would change. There is consistent lateral movement of the chain at the same degrees of crank rotation. I can setup the FD so with my largest chainring I can use cogs 8,7,6,5 without noise but at cog 4 there's a slight ding...ding...ding...whenever the drive side pedal is upward.

I can't post images yet but I have 2 showing the lateral chain movement in the largest chainring and smallest cog. I don't know if this would be considered within reason or if something is bent. I'm a heavier at 95 kg and am relatively new to cycling and have generally been at a lower cadence and higher torque and maybe cheaper cranks can't hold up to that over time?
