I’ve starting having problems with my prints lately. I don’t know what’s changed, but I’m starting to get warping off the bed as per the attached photo.

It’s PLA, print temp is 195 & 70bed. I’ve tried with a PVA/water solution that I use on my other printers (and it’s worked in the past). I’ve also tried a completely clean bed wiped with hydrogen peroxide, which has also worked in the past.

I’m trying to print new parts for a CoreXY, but it’s frustrating me and wasting filament more than anything.

Any help would be greatly appreciated. Thank you in advance.

Try checking your temps and calibration.

I would try to reduce the bed temp a little. 70 deg seems a bit high for pla in my experience. I usually run 50deg bed for pla. No change in material brand?

4

@Mike_Molfenter no. I’ve been using Hatchbox, which has been printing amazingly on this, and my other printers.

Normally I print at 60deg.

5

60 degrees seems to be my sweet spot and I use hair spray on it for “extra hold” pun intended. After several layers I learned you can back the bed temp off 5 degrees or so.

6

You all print way higher than I do: for PLA, 40C for the first layer and I turn the bed off after that. I found, when trying to print wax filament, that if I spray the bed with some 3M Super77 adhesive, it sticks to the bed so hard sometimes the PLA delaminates and leaves a bit on the bed.

7

First off look at the amount of squish you are getting on your first layer. If everything worked fine in the past and nothing is working right now, it almost always means the initial z height is a bit too high off the bed. Especially with a filament not very prone to warping like PLA.

8

Maybe the hairspray has changed and causing lifting as it cooks on the bed.

Did you try anything new lately? Filiment, temperature, …printer?..

I had this problem when I had my printer by the window during winter

It’s indeed a temperature problem, the first layers get colder which create the warping. Apart from recheck your environment, you can had a support… or check https://www.simplify3d.com/support/print-quality-troubleshooting (their FAQ resume almost all problems and general hints to solve them)

Since this issue just started it may just be a bed leveling issue where something just got bumped. Releveling could very possibly fix this!

13

I agree with those suggesting bed leveling / nozzle distance to bed for the first layer. I have an unheated bed and have found that if I make the start distance too small (lots of squish), it’s almost impossible to get the print off the bed. I use blue tape.

14

Blue tape (get the 3M brand), wiped down with a bit of isopropyl alcohol, has been my go-to for PLA.

15

I use Blue tape and a couple bargain brands from Amazon, esun/AIO, I run my first layer HOT typically like 75 - 80 for a bed temp and then back it down to 60 for short/small prints I’ll back down even cooler to 50 if I have a larger print going that might run beyond a couple hours. Have you printed from this roll before with no issue?

16

I always print PLA at 215 and 60

17

I use ruff tape and hairspray, works perfect. No heatbed.

18

I use similar approach to @John_Bump for PLA, but it will obviously vary by printer (cooling fan, enclosure, etc). The warping really indicates to me a thermal problem rather than an adhesion one.

19

Can you invent and print me a prototype of a simple product that solves everyday problems? I’d love to test it for the As Seen On Tv shelves of Walmart, CVS, Walgreens!

on my startt i’ll print with PLA 0° Bedtemp and simple gluestick. after print, put it into warm water to lose the adhäsion from the stick.
