Hex key and mini clamp came in handy for battling a lifting edge

This really summarises the passive aggressive level you get to with a 3D printer: “Lift off the bed now you little fucker!”

You must have been really close to the end for that to work. I've tried many hacks but few really work for me in-situ for more that a dozen layers.

There wasn't much left and nothing that would collide with it. Seemed to work well enough

I usually use glue stick but just ran out

Usually? Like for routine pla prints? I've found myself having to do this (man I love magigoo) but the masses say I really shouldn't have to. Kinda validating if this is actually a thing.

If you have corners lifting during big prints it's nearly always due to a bad first layer or warping. An enclosure, even if it has an open lid since PLA doesn't really like high enclosure temps, would probably do wonders. But if you have an i3 style printer, enclosures can be kind of a PITA. You could also try a draft shield. Basically tell your slicer to print a skirt that's the same height as the print itself.

Pla can also warp when not cooled enough. Although with a a decent textured Pei sheets you should never have pla adhesion issues honestly

Have you tried hairspray? I definitely prefer it as it's easy to put on and gives nice, even coverage.

[–] [email protected] 1 points 11 months ago

Not yet, I need to try that

[–] [email protected] 3 points 1 year ago

Have they not invented blue painters tape where you're from?

I oddly usually have the other problem, my prints stick too good, the bottom of the print is white (though it is black PLA+) and it sometimes deforms my magnetic mat doohickey while trying to pry it free. Drives me crazy.

Your extruder might be set too low.

[–] [email protected] 1 points 11 months ago (1 children)

I'll try turning it up, iirc I have been running like 220° for PLA+.

[–] [email protected] 1 points 11 months ago (1 children)

I meant your extruder's z-offset it too low not the temperature.

[–] [email protected] 1 points 11 months ago

Ahh I can try raising it, thanks!

It's an LED strip diffuser, this is the mount part

I had a huge problem with lifting edges. But since I bought Dimafix Spray all of my issues are gone. I also use brim with increased size to ger near perfect result. I print ABS.

[–] [email protected] 2 points 1 year ago

I usually use glue stick and never have issues but I just ran out.
Brims are a good idea for the meantime though

This is only PlA+ so it should be behaving with a heated bed alone

[–] [email protected] 1 points 1 year ago

I've only done 3 prints with abs but I used a g10 plate and it worked fabulously. I heard one of the damn prints pop off the plate with a snap when the bed dropped below 60c, that was wild to me.

I also found a huge difference between filaments. Creality was terrible for me, Reflow is great

Ever since it was suggested to rub glue stick over the print bed beforehand, I haven't had a single issue with raising bits of my prints. Bought a huge school supply case of them like 4 years ago. I've used up 2 entire sticks.

Though skeptical about trying it at first, I've found that Aquanet hairspray works amazingly on those creality glass beds. Keeps PLA on, and prevents PETG from bonding.
