Bed Leveling for Beginners (Page 5 of 5)

That did the trick, tried to level acc. to your method but still it didn't seem to work Reading this I tried the center of the bed and there I was way of. So finding the compromise did work. Thanks! Great you guys share your experience.

No Problem, glad it helps. Beats the rocket science needed for the built in method.

I have a daVinci AiO.
Tried to print a couple of things - test was ok, a small part was ok, but a larger piece was a mess, with everything at the front being a pile of spaghetti.

Suspected the alignment front to back (i.e. the Y axis) was off, so followed the instructions here, and it showed that I was right - the front was way lower than the rest.
Just made some adjustments and am waiting for the next print to get under way so I can see how it worked.

........edit

an hour later and the print is fine.
all the issues which plagued the first run have gone.
Thanks for the info.

I preform this and feel Ive properly adjusted the back left, back right and front center adjust knobs as per the directions in this thread.
My question is am I supposed to be able to move the nozzle and paper anywhere on the build plate with the same resistance? Because although points 1, 2 and 3 have equal pressure I feel as though the remaining front corners have different levels of tension. Especially the front right corner feels as though it has the tightest gap and I find it difficult to slide the paper around and when I start my prints during the printing of the purge line the extruder makes a ticking noise as if there isn't enough space for the filament to flow freely. Loosening the knobs in order to free up this corner results in the original corners now feeling too loose. Am
I doing something wrong?

this recently have been very frustrating for me to say at the least. When I first got the DaVinci 1.0 printer - I didn't have to calibrate. I printed out some good prints then just recently went back. I noticed the enclosure case for my project I"m working on was messing up constantly. I looked over Youtube tutorials and such - got a dial indicator but even find that one hard. I bough the amazon app Davinci Calibrator and it works okay but when I run a print either the nozzle too close to the print bed. Just now I used the dial indicator and it's always been 0 - back left; 0 top left; 95 on top right and 0 on back right. I printed a quick smiley face magnet case for the fridge and the nozzle was too close to the print bed. I had to loosen some knobs to get the grinding to stop. It's printing now without grinding on anything. I'll try the paper trick possibly tomorrow because as for now I'm taking a break of re calibrating.

The thing to keep in mind and the main reason for me creating this guide is that the values that XYZ gets you to set in the 250 range represents .25mm and that is too high..

You will not get good adhesion if you are printing at .3mm.. The ideal height should be no more than half of your desired print layer thickness. It is not a number that is constant but a number that needs to change depending on your desired layer thickness.

For example if you ever wanted to go down to .1mm on the layer then you see that .25 is actually thicker so you would need to actually go down to .05 on thew first layer.. A set of feeler gauges is really preferred as then  you have an assortment of thicknesses for different layer heights.

Amazing. Saved countless hours of headache. The only trick part was accounting for the unevenness of the bed - the middle has a slight bulge. So as mentioned, I had to compromise. But dude...very happy to be printing away!

Is this a new problem, or has it never printed?

Have you cleaned the head?

Just wanted to add my thanks to this thread, we are a school who has recently purchased a davinci and we eagerly unpacked it last night, failed the auto calibration but tried a print anyway, it went horribly wrong and i have what has been described by one of our teachers as "the droppings of an epileptic spider" on my desk.

After following this simple guide on how to level the bed, i reran the same test and i am now sat happily with my demo heart cooling off on the bed.

Thanks again, myself and the school are looking forward to many years of awesome project (and maybe some personal )  3d printing!

You should calibrate as you would print. That also means both the bed and hot end should be hot to account for expansion.
