1st layer prints great everything else extrudes uneven

Good Afternoon,
1st post here so I apologize if this is an extremely basic question. I have been printing for years on a Robo 3D R1 printer for custom rod handles I make with Carbon Fiber handles. Never had an issue that had me stumped. I just can't seem to figure this one out however. I have attached the image of the print of a 35mm square box for calibration and as you can see the extruder is doing its own thing. I have attempted the following:

• Cleaned the extruder and nozzle
• Cleaned the drive gear
• Adjusted the spring tension on drive gear
• cleaned print bed
• adjusted extrusion temperature up and down

My next step will be to try a new filament but I am not confident that will resolve it. These same settings have worked flawlessly in the past so I am having troubles determining where to go from here. Any input would be greatly appreciated and once again I apologize if this seems like common sense as I have been self taught keeping the R1 operating.

I forgot to mention that I am printing an ABS 1.75mm. My heat is set to 225 degrees C.

Attached is the results of the ice rods I make using abs 3d prints as the core of the grip

have you lowered the printing speed ? check if the drive pulleys on the stepper motors are screwed on tight?
