problems printing

I need help solving a problem. I have a Robo 3D R2 that started printing crap on the right side of all of my prints. I've adjusted everything I know how and it doesn't work. Robo no longer repairs their printers. They are baffled by it as well. Has anybody seen this? Please help. I've ordered a Prusa Mini but it won't get here until June. Thank you.

not sure what I'm supposed to be seeing.
looks like wood filament - which is always rough till you sand it.

so what's the actual problem as it 'looks' fine to me.

I was using regular PLA. The left side is smooth.Attachment 14239 No matter what I do one side is always rough while the other side is always rough and jagged.
