2. If you are indeed using PLA filament, use blue tape. The one people use when they paint house. It do come with different color, but for reasons unknown, the blue color stick best.

I totally disagree with this.  Green Frog tape has superior sticking power to the glass than blue.  W
What happened to me with blue tape is that the part would stick fine to the tape, but the tape would pull up from the bed when I would remove the finished part.
With green, it works great.  Thats my experience.  YMMV

3. double check your z offset, the nozzle should be 0.1mm-0.2mm above the bed. if space is 0.25-0.4mm, it will print normal in the beginning but unable to stick later.  if space is smaller than 0.1mm, you will have trouble to take your print off bed.

4. change blue tape every 4-5 print. also make sure soap wash your hand when apply the blue tape. sweet, lipid and grease on your hand will prevent PLA stick to blue tape.

5. google keywork ABS juice, glue stick, jello together with 3d print, many useful tips.

I would guess that the Z offset is to high and the part is not sticking to the bed.

I would agree.  Look at the test strip on the right, thats not even printing well.

Is that fresh Frog's tape?  Clean it with isopropyl alcohol first.
