I'm a beginner, so my terminology may be off.
I bought my first 3D printer a while back It's the first Creality Ender 3 S1 series that came out.
I'll summarize my observations: Manual and auto bed leveling don't seem to catch all the inconstancies on the bed. The first layer is either too loose or too squished because of these differences. I can't seem to find any visible inconsistencies when using a ruler to check the bed at problematic points manually. I'm constantly adjusting my Z-offset to find the right height, but can't seem to find it.
Problem 1: Manual and auto bed leveling
I'm following the following steps:
- Tighten all springs
- Move the Z-axis to 0
- Loosen springs to bring the table up and allow the springs to breathe
- Use Z-offset to bring the nozzle to the table
- Use a sheet of paper to feel a slight friction between the nozzle and the bed
- Move the nozzle to four corners (~ spring mount points)
- Move between each corner until satisfied with friction
Well, I don't really get to step eight, because I'm never happy with the friction. As soon as I move to the next corner, the other corners deform to the point where there is no friction at all. The springs are not too loose, so I don't think that's the problem.
Problem 2: Build plate deformation
When I'm finally kind of happy with the manual bed leveling, I return to auto-home. To my surprise, the nozzle presses hard against the surface. When I disable steppers, I notice the nozzle is still at the correct height as measured on the four corners.
There is also a small spot on the plate (1x2 cm) where the nozzle seems to press into the plate as well.
Problem 3: auto bed leveling
Now I'm thinking to myself... hey! auto bed leveling to the rescue! Well of course not. The 1x2 cm square I'm talking about does not get picked up. And the PLA on most parts of my bed is either too high or too low.
Problem 4: Z-offset and adhesion
Finally, as I mentioned, it often prints too high or too loose. But I can't seem to find the right Z-offset at all. When I move it down too far, it squishes, and when I move it back up a bit, the previous PLA loosens and gets pulled off the table on the next past (or even immediately after the first pass)
Things I've done:
- Contacted Creality, they're really good at google translate...
They sent me 1x motherboard, 1x print head, 1x print plate, 1x print bed
No real help... just going in circles and some vague instruction video's on their part
- Updated firmware to the latest version from 21 October 2021
- Bought a glass bed and installed it
- Adjusted all wheels on the X- and Z-axis
- Adjusted the belt tension
- Cleaned and greased both T-rods
- Degreased the bed plate
- Printed with bed @ 60 ° and 64 °C
- Printed with nozzle @ 195 °, 200 °, 205 ° and 215 °C
I'm sorry if this question is too broad. I've had this printer for a couple of months now, and tried a lot of things, but I've never been able to start a print and go for a coffee... it always fails.
Greenonline pointed out that this question should be split up into separate questions. But to my beliefs, all four problems mentioned below might be relevant to pinpoint one or two remedies for the issue I'm having with this printer. So my question should be this: Maybe someone with more experience can see a correlation between the problems I'm having.
Help a newbie out, please :)
As soon as I move to the next corner, the other corners deform to the point where there is no friction at all.that is not uncommon, it may take several rounds to get this right. Note, you have a sheet of glass, so, if that is perfectly flat, you should have no trouble setting the correct level or distance for that matter. If that doesn't work, either the printing tuning skills aren't there yet (no offense, mine weren't good when I was a beginner) or you have an unsurfaced hardware issue. I doubt whether we can fix this, although we want to, with the question in its current state. $\endgroup$
