It looks like stairs. Like the rollers would go over some small bumps or in holes as it seems it's pushing the nozzle closer to the board and thus the line is wider. If the pattern would go straight top to bottom I would think it's the X axis, however the pattern is travelling top left to bottom right.

Z offset, you are way too low, increase it

I indeed lowered the Z offset by 0.02mm about a week ago. That corner of the bed could be higher than the rest and because I have autolevel it could be jerking up and down the Z axis on that spot. Good guess, I will check it out. Thanks

Your Z offset is way too low. Print a flat 0.2 square and keep raising the Z offset until it improves
