[Layer Splitting PET-G]

With PETG you want to run the printer with as little part cooling as you can, for parts with no details you can run with 0% cooling fans to get strong layers, if a part as more fine details run cooling fans at 50%.

 

If its printing in a area open to cold drafts, its best to try and limit the draft (for any 3d printing really) to stop it cooling to fast. Also you might need to up the printing temps to get better layer adhesion, or print a little slower.

 

this is awesome advise Carla, will try all those tips and let you know.
Thanks!

I've noticed that when I printed at slower speed I got better layer adhesion.

 

Thanks! I will try that, also to prevent blobs and boogers...

Not necessarily, but it helps of course.

Don't use the part cooling fan for those big objects and try a different filament first.

If this is "silver", use a different color - i don't know why, but these glittering additives make it much more worse.

 

The other one I bought was Cobalt... A lot worse than the silver one...
Yes, we don't get quality filament in Argentina, but I wanna get the best results with what I get, and I think I can do better by tuning the settings.

Thanks!

Hi Guys!

 

I had this kind of layer separation. It coincides to the side that isn't facing the wall. I think this is due to the material cooling and contracting, am I right?

Do I need an enclosure?

 

Thanks!

[Super thin first layer]

Hi guys!

I figured it out... Turns out I had misclicked when disabling the steppers to calibrate, and saved an offset in the Z axis. When I leveled it was ok, because I had it placed at the 0 of the machine (with Auto Home), but then when it started printing, that Z offset was sticking it too close to the bed.

Sorry it wasn't software related, I'm super new in this, and it's a lot harder than I initially thought it was going to be.
And I'm loving having to learn so much about how to print, even more than actually printing.

 

Thanks a lot for your comments!

To illustrate... I want to be able to diagnose a print by looking at the artifacts, I'm not there yet, clearly 😛

 

[Super thin first layer]

Hi Guys! I recently purchased an Ender 3 Pro, and I love Cura for a Slicer. But my first layer is super thin, and even though it sticks on the bed, it gets really hard to take out, and sometimes it does weird things on the first layer.

It looks like it isn't enough plastic.

 

I've adjusted the bed with the paper pinching technique, and I think I got it right.

 

In all your expertize, who's fault it might be (in the end my fault of course), my slicer settings, my printer assembly, the rubbish plastic we can buy in Argentina, the e-steps?

I don't know what else to change. I'm now testing PET-G for the first time, and it behaves the same as PLA.

 

Thanks!
