Thanks, I did a temp tower, 230 gave the best, the higher I went, the more stringing appeared.
Someone on a cr10 facebook group asked if I had zhop turned on, I didn't.
I will watch the vids you posted in my other thread (that was with a different main board) and try again.
I presumed (possibly wrongly) that if it's hot enough that the material sticks to the bed, that's all I'm after? (will google it). One thing that currently works very well on my V2 is the Creality bed. At 50, PLA sticks like glue, wont budge at all, let the bed cool down and there's virtually zero resistance, prints just fall away, at 70, the small temp tower takes a lot to remove before it's cooled down, will try increasing a bit (after reading up on this) and will see.
Thanks again
