Warping/shrinking PLA problem

[Scibbles]

Thanks for the advice guys

I was using aluminium bed with Wanhao tape, but hadn't wiped it, so gave it a good wipe with alcohol. Will try the brim or mouse ears if this happens again.

Yes, my PLA is pretty cheap at £18 a kg. I have used some even cheaper with better results at just £12 per kg (from eBay), but guess I got lucky.

The first layer does print slower, but not that slow, will try this as well.

I didn't think I needed to heat the bed for PLA, but did this time (to 50), and following advice from both of you, the print came out perfect... well, best so far

Many thanks for your help

Would you recommend using glass on my bed? my thought is that I wouldn't have to keep levelling my bed if I remove my print from the glass, away from the printer. Instead of scraping it off on the printer, possible knocking out my levelling.
