Hi All
Being relatively inexperienced, we are finding prints with large footprints are curling at the edges on both Z18 and Replicators, any tips. Extruder is @ 215c.
Cheers

Hi there
Print large prints on Raft. This helps with adhesion and prevent warping.
yep and as you don't have a heated bed - raft is a good idea.
The other way to go is use pet tape and thick layer of gluestick.
Not sure how you'd get the prints off the buildplate though. I usually heat my plate up so I can get a scraper under to lever.
Without a heated build plate some of my larger prints would robably still be stuck to the plate :-)
We are using rafts, printing the same file on both z18 and replicator with the same result on both heated and u heated platformsQuote:

Another option is a product called wolfbite nano from airwolf 3d.. it's relatively expensive compared to home brew solutions, but it does work extremely well for PLA.. a little will last you quite a while.
Thank you will give that a try, we are struggling to maintain ambient above 17degC I suspect this might be a cause.Quote:

At the moment it's 20 and 57% humidity - which is pretty high it's usually between 40-50%
Excess humidity is supposed to effect pla - I've never noticed it and the stuff I use a lot doesn't get stored in bags anymore.
Another thing that might be occuring is the auto calibration might be leaving too large a gap.
Is that adjustable at all ?
Helper disks. I use them on the edges of my flat prints they really help. Used to be part of the Examples but now I grab them from Thingiverse and add one to each corner in the Makerware before hitting export.
