Make sure your belts are tensioned. That the drive pulleys are tight on the motors and not slipping when your print and calibrate the machine's_Calibration_Guide

Looks like you have a couple problems. Belts could be one of them but what sticks out more to me is the inconsistent extrusion. This is most likely your extruder skipping steps, this would be easy to hear as it makes a click when it happens.

1. Increase torque by adjusting the voltage to your stepper motor
2. Calibrate your extruders step/mm
3. Print slower

If you need some help, or don't understand what I just said, feel free to send me a PM anytime

Is your filament size set right in your slicer?

Yes 1.75 Thanks

I don't believe it is 1.75 exact. Maybe something between 1.65 - 1.70

What slicer do you use? and What nozzle?

I had similar issues when i let Slic3r decide extrusion width automatically based on nozzle size.
I had to define all widths the same as my nozzle and use a digital caliper to measure my 1.75 filament was actually 1.7

Also, is that your first layer in the picture?
You want to make it 150 - 200% in the Slic3r, because the first layer is what you define it + the real distance between the nozzle and the bed.
