Bedleveling Help

So im not really sure what my problem is now.
I have a PrintinZ board now (man alive does that make it easier getting things off the bed...), and when i print small things it seems to be printing fine (example: https://imgur.com/C3HumCh ) but when i try to print something larger, it does these weird things:

From what i can tell the odd rough/bubbly surface is usually a result of too hot. But im printing at 195C and when i try to lower it further i get massive bed adhesion issues.

Print settings:
0.4mm layer height
0.8mm wall/top/bottom thickness
nozzle temp 195C
bedtemp 50C
print speed 50mm/s
travel speed 100mm/s
layer X offset 0.1mm
Cooling 100% fan speed at layer 2, 0% otherwise (not seeing how to change this per layer in Cura)
plate adhesion type = Skirt

The x offset is because i feel like when it goes to print it lowers slightly more than what it was at when i leveled it. It seemed to help but it could just be in my head. I also started using 2papers thick to calibrate the bedlevel.

I have no real idea what its doing. 
edit: also theres a spot on my board as you can see in the image that just doesnt wanna print properly. It acts like that corner is too low but...the closer to said corner the nozzle gets the better it gets. So its too low in the middle of the bed somehow? The offset nuts on the bottom are as snug as i can get them, bed doesnt wobble at all.

Initially only once but then i thought i might be messing it up as i move along so i went to each corner 3 times.
Standard white paper from my printer, about 0.1mm thick

Bedleveling Help
So i am having bed leveling issues, but the problem is the method im using to level the bed or atleast it doesnt feel like it:

1) Home all axis
2) Move the extruder head to one corner
3) Using a piece of paper, level the bed until its just barely applying any force to the paper, then slowly back off until i dont feel any pressure when moving the paper
4) Repeat 2-3 for all 4 corners

This is how i am told to do it in every single tutorial i can find, some even recommend i should have moderate resistance on the paper.

But when i goto print, the nozzle seems to smash into the bed enough to cause the "squished extrusion" issue, which both messes up the first layer and embeds it into my blue printer tape so hard its a bit of a nightmare to get it off.

It feels like when it starts to print its actually going slightly lower than the Home Axis sets it to, which makes no sense to me when before it starts printing the first thing it does is home the axis. I'm also getting a lot of the extruder "popping" noise which i found out is a result of either A) too much extrusion which im not sure how to check in Cura or B) the nozzle is too low to the bed.

The only way im getting decent prints is to literally adjust the bed while its printing until it stops the extruder popping noise. Which, while it works, is extremely annoying to do.

Is there some additional trick to leveling the bed other than the paper thing? I've only had one actual failed print per-say but i have to baby this thing every time i start a print to get the bed level right (part of that issue is i have to yank on it pretty hard to get the part off, even with the tape, waiting on a PrintinZ mat to solve that)

edit: might be possible i need to calibrate my extruder. I'm printing some wide parts and noticing the bottom layer is very rough/uneven looking. And while its printing the initial lines its "dripping" rather than drawing with the filament...

Extruder jerking problem
i'm printing PLA at 215C.
I swapped out for the titan extruder and at first i thought it was fixed because i didnt hear the noise, but its probably muffling it because its still doing it.

I went through the voltage adjustment process and tuned the voltage on all my motors to 1.01-1.06VDC, they were all around 0.85VDC before so i definitely needed to do that anyway. Still not working.

i'm at a loss at what else to try other than MAYBE somehow because i have the extruder all the way at the top its too tight a bend?

edit: Apparently the motor intended for the titan extruder is reversed compared to the normal motor. The titan came with my purchase, i didnt buy the standalone box. As a result they did not give me the mini-motor or the large heatsink. I just swapped it out and realized wait a minute...its going backwards...
Tried moving it in various ways but the only angle i could find that would extrude correctly would be impossible to use w/o having a massive bend in the tube.

Swapped back to the normal extruder after having the voltage adjusted. It seems to be working now (though i think my bed needs more tuning as half of my 150mmx150mm testprint square isnt laying very well). So i guess it WAS the voltage after all.

Why the heck would they give me the TItan extruder if it doesnt work with the stock motor?

Extruder jerking problem
Hi, i just built my Tevo Tarantula and from what i can tell its working fine (heating up properly, its properly leveled, the axis move cleanly) except the extruder does this really weird jerking motion where it appears to be pushing properly, then it pops backwards a bit, ending in not pushing anything through since it just yanked it back.
It was working for about 2-3 minutes, long enough for me to feel safe letting go of the power plug because it was printing fine. Then i heard this odd noise and found it to be the extruder. See youtube video 
of what im talking about.

This doesnt seem to line up with the jittery issue ive heard about where amping up the voltage a little bit fixes it (havnt tried, but its not jittering so i didnt bother).
