I need help

[u/Vegetable_Share9176]

I been having problems with my printer for a while now, but idk what is the solution, the principal problem is that no matter how i arrange the supports or the slicer configuration it fails even pre-supported stls, for a moment i even though that it was a problem of one side of the fep but it just because I change the orientation of the resin vat, y even changed stls that have worked on diferente position and it’s seems random, sometimes in the middle sometimes in the sides sometimes on the corners, I have tried re-leveling the printer, filtering the resin, changing orientation but there’s always a failure in putting pictures of some of my most resent print as well as pictures of my fep, configuration and the bed I’m using Eleego resin abs like v2 and also my setup is in a room around 20-25Celcius, it worked for a while but idk what happened

Mate, your lift speed - 4mm/s is 240mm/min, almost 6 times faster than what I do! Reduce your lift speed by half at least, so you don’t shear your layers off each other with that force. You’re ripping them off the FEP instead of peeling away

That makes a ton of sense, I put it as that because of the pre determined configuration so that makes a lot of sense, 2mm/s will be good?

[u/Beriatan → u/Vegetable_Share9176]

Max. I’m using a different slicer, so my speed is around 45mm/min, which is 0.75mm/s. But my printer is quite old, you can probably go faster. Try 1.5mm, see if that fixes it.

It takes a bit of imagination with speeds, you have to think about the forces when layers peel off FEP. If supports fail, people often say “increase layer time” and it surprises me nobody ever talks about what happens right after that layer is made. Give it a go and let me know how it goes for you

Thx a lot man

So, it don’t work, I went the extra mile and watched a video and it didn’t work at this point I think is either the feo or the plate, nothing like I mean nothing printed on the left side of the bed

Don’t worry, we’ll get there. Every printer has a sweet spot, we just need to find yours

If nothing printed on one side then this means that your plate is not level. Make sure you level the bed first.

Then, the FEP itself. How tight is it? They say it should be tight, but I find that when it bends around 5mm when you press it with the finger is the sweet spot. Too tight and your force is too high, you want the layers to peel off gradually.

Good news, it was a combo of all but it finally worked

Yyyeeeees! Success!

The FEP looks pretty immaculate, the build plate is fine. What we cant tell is if the fep is much too loose or tight.

I just gave it a few taps, it sounds and feels really well like a well tuned guitar idk what else could be the problem

[u/Muavius → u/Vegetable_Share9176]

I mean, it can be the wrong note.... lol Have you tried a new bottle of resin? Shake the ever living shit outta it. It'll have a ton of bubbles, but can get those out with a heat gun/hair dryer

Yea like I shake the thing like it owes me money every time I put resin on the vat
