Prints warping and coming off bed

I am currently using blue painters tape (3M) and a 60 degree C heating bed, which I have found gives best results. I have read online that painters tape is best without heating, but it just won't adhere! I am trying to regulate my ambient temp at around 25. I am currently trying to print square pillars to support my PLA filament roll, and since it has to be tall, I have found that the nozzle sort of rubs against the pillar, making it fall off... so I decreased PLA extruded, but then it became really weak. I have also noticed warping ON THE PRINT!!!??? Every few mm or so, I see some lifted corners (tiny gaps) that are weak spots. I am using the PLA given to me with the printer (I am a newbie that does a lot of research), wondering whether it's my filament's problem? It's 1.75 mm, the nozzle is 0.4 mm, and my model is prusa i3 electron. Btw I'm 99% sure my height (nozzle to platform) good.
Can anyone recommend me some good filling shapes? I'm using the default honeycomb, I can't find anything about what each filling pattern is good for and their pros and cons.

Also, does anyone have any reprapchampion.com discount codes? And where can I get those puny tiny little allen keys (really REALLY REALLY small)?

My advice is to use 3dLac

this is a spray-on solution that sticks wehen hot and releases when cold. It works ok on Glass and even better on aluminium.
Warping with PLA seems impossible.

I use 3Dlac on 80 degrees centigrade bed. You can not tear stuff off when hot. It takes off when cold.

If you have bad adhesion between layers it's normally a sign of under extrusion. Solve your problem of bed adhesion first and then increase your extrusion.

Uh oh... I have just realized that the power supply to my motherboard wires get so hot that the rubber melts, I touched it and got burned (I'm pretty stupid)! Any idea why? I'm not printing until this is fixed, I'm worried af

BTW I'm at 130 for the first layer, then I set it to 110 for next few

Wise choice to not print until you fix that. What gauge wire are you using? There could be an electronics problem somewhere that's causing too much current draw, definitely don't leave it on and unattended.

how do I get 3dlac???

i really dont know. ill post an image soon.

Try wiping the tape with IPA before printing. The problem with heating painter''s tape is that the adhesive bakes onto your bed surface and becomes very hard to remove. PLA sticks to warm kapton and PEI very nicely without any sloppy sprays or goo. You can get a 300 x300 x 0.76 mm piece of PEI from Amazon for $15. It will last a long long time if you don't abuse it.

What parts are you trying to print, can you not lay them flat on the bed so they are not so tall.

I print pla on blue painters tape with bed temp at 50-55 deg, It sticks very well if there is enough suface area of the part in contact with the bed, smaller parts may need a 3-5 mm brim to help prevent corner warp, allso a part cooling fan will help.

If your nozzle is scraping the part when it gets any height then your Z steps/mm may need increaseing a bit(my M5 rods ended up at 4030steps/mm) measured over a 180mm Zmove

The problem is my prints warp, so i cannot lay a big flat side on the bed. I am starting to doubt the filament quality (not even 90% sure yet though), it sticks for a while, then comes off. I will look into the Z step.

I cannot print until i fix my melting wire problem.... Im out of ideas. checking my wiring once more.

Does this ship to canada? thats where i live. sounds interesting. and from what ive read is pretty reliable

and can i just clip glass to alminum? cuz aluminum is my screwed on bed, i wonder if the heat will go through

im using the one the printer came with, never noticed it before

Then it's likely either a connection or electronics problem. Can't tell you much more without any additional info.

thanks, i will check all my wiring and get back. but must bake time for wiring first, have lots of hwk right now these days

THANKS ALL!!!
i checked my wiring again, and found some inaccuracies in the diagram i followed, found a pic, fixed my problem. the wire is about 50-40 c im guessing, warm to the touch.

For all that r printing with blue painters, i have found the magic solution: take an alchohol swab -- i used antiseptic isopropyl-- the medical one-- and wiped my tape, the print stuck on se well that i couldnt get it off without taking off the print.
