Just ran the same print with a brim and no lifting

Will get a glass bed when I find a place to source the glass from!

glass is the way to go. get to you hardware store and they will cut it for you. its cheap! and so is hairspray. at the very least get some picture frames and use that.

what version of solidoodle is this? standard or more expensive kind? the heatbed must not be warm enogh when you started printing. or do you have a heat bed at all?
i can't believe the warping is this bad even with a heated bed... (i have ad2 standard, so i know what it looks like without heatbed)

I am using glass. It is slightly less sticky than the kapton, but has other benefits (look up for more info. Read through the solidoodletips wordpress blog- google this } just recommendations)

But when I'm feeling lazy and don't want to tune my print though it needs tuning, or when I have something with a tiny base and brimming won't be enough, I throw down some ABS glue.

I made some last night and it reallllyyy makes things stick. There are recipes online but I just filled a small bottle with approximately 70% acetone, and the rest was chunks of my failed prints. They dissolved overnight (20 hrs before I returned to the bottle) My application process is a very metered "dump a bunch on my print area, and smooth it out a bit if it's too thick." I do it before I heat the bed or before the bed gets above 50C. Then heat the bed. (I once did it after 50C and just got a weird foam. It still worked, but it's less safe to have bubbling acetone than slowly evaporating acetone.)

Yeah, then print on that. It's kind of like the mother of all brims.

Still, you want to first perfect the usual process of making sure you squish the first layer well, use good temperatures, and occasionally clean your kapton.

another thing you can try is to increase your first layer width and slow the first layer print speed down. Along with the brim and the hairspray, you should be in business. It may work too well though. I just lost a 2 hour print because it stuck so well i destroyed the part trying to get it off the table. I had my brim a little high (15mm) and i'm really pushing the first layer down hard..

I also use an extruder temp of 200 on the first layer and a bed temp of 95, then drop to 195 and 90. I've only had the print for a couple weeks and really only started printing with it over the last couple days so i'm still experimenting..

Thankyou both!

Longer term I'll go for glass+hairspry and sides, but hopefully the brim will help me in the immediate.

Once you see an edge start to lift,save yourself trouble,kill the print and start over.

What works for me:Clean the kapton with acetone(watch the fumes).Apply a light coating of Aquanet super hold hairspray and let dry.

Before slicing the file,open slic3r,click "configure'.When the dialog box pops up,click "print settings",click "skirt and brim".

Look where it says "brim width",you can set a value of 4or 5 mm(or your choice),click "save print setting".Slice the file and print.

What the brim does is put down a layer much like the brim of a hat.This gives your print extra adhesion to fight warping.The brim is easily broken off when the print is done.

Hope this helps,good luck!

I suppose that you are printing on the original bed with the Kapton on it ?
You could sctrach a little bit the kapton with some sand paper(400-800)but you must be cautious, just a little bit.
The better(that's my opinion)is to use a glass bed with some hair spray on it , take a look there :

Also it will be a good idea to close the printer(the sides) with some woods or glass or PVC or else it will help to have a better temperature inside the printer, that helps to stuck the ABS on the bed.

Your bed temperature must be around 90°(for ABS and 60 or cold for PLA).

Hi there,

Got a Solidoodle 2 for my b'day that I'm trying to use... having some issues with trying to print a GPS housing.

Basically my edges keep 'curling' up. This sometime means the print comes unstuck also...

Have attached photo of example print... any pointers on where to start looking?

Thanks in advance!
