Help with Big Prints are bad

[DarrenAnton]

When I print small things it's OK, Big prints are not good at all. Bed level is real good spent hours on getting it just right

I printed .6 tip and .4 tip same problem

The Effector Platform does move around a bit (It's loose) but it's the way it was built. From what I understand it the way they built this kit.

Do you think replacing the Rostock MAX Delta Arms with carbon fiber rods and a new Effector Platform will help with Bigger bad prints?
If so whats the "Best" Kit out there?


I did a video of the problem here...

It looks like it is squishing too far down in to the heated bed.

To check try to increase.the first layer thickness. The nozzle will not be so far squished.

Thanks, But software will not let me, its a .4 tip printing at .4 layer height and 1st layer height that's the max it will let me do (tried the same with the .6 tip and .6 layer height)

Couple of thoughts that involve no money.

Try placing tight rubber bands around the arm pair about three inches up from the effector. These should be tight to the point of almost squeezing the arms together. This tightened the effector up considerably on my V2. I think the flat clamps that fits around the u-joints are a bit whimpy.

For the area that is squishing near the Y Tower, I have also had that problem. I largely corrected it by making sure that the tower located on a radial line passing through the problem area was a square as I could make it to the bed. From the consistent squish in that area, I suspect that the tower may be leaning towards the center of the bed.

Good luck and I wish that my bed was as consistent as yours every where other than the problem area!

Ive had similar issues in the past... Its either a combo of bed leveling and screw stop on your bottom right tower.

Whats happening with your thin then thick is that the pressure is building in the nozzle in the bottom right hand corner and unable to extrude the filament, so when it reaches a point in which it has the clearance to force it out, BURP you get the blob.
I know it seems like its level (and you are getting some layer, just super thin.) it may only be off by .1 or .05, but id bet my 2nd child thats it... I had the same exact issue.
