Problems tramming bed

Bambu Lab X1 Series

Hello,

I tried to tramm my bed, but got some problems. I tried to do it from the manuel at:

First, the screws are very tight, making it almost unable to get to the starting position descripted in the wiki.

Then I find it hard to tell when the taget position “nozzle should only touch the bed” is reached only my watching the nozzle. It seems the nozzle easily digs into the bed when the screws are tightened to much.

Then the time the script gives you seems to be very short for me to work accurate. I’m always afraid that the nozzle will move when I’m to low so the bed will get scratched.

Is there any other way to do the tramming, like using a water scale or so? Or using a peace pf paper to determinate if the nozzle is deep enough?

Hi, do you have a plate on the bed? Does it dig into the plate? Or did you do this process without a buildplate on? If so put a plate on asap, the nozzle will damage your bed. As Bambu suggests, the best is to use the engineering plate as it is flat and harder than the cool plate.

I use a small flashlight to light the plate behind the nozzle, and view the gap with my eye at the level of the plate. That makes it easier to detect the instant the nozzle touches the plate. If I have any doubt on the first three adjustments, I leave them ever so slightly high rather than too low. After you’ve trammed the bed a time or two, you’ll will actually wish the nozzle moved to the next position sooner.

Here try my bed leveling tool over on Printables.

I was noticing ALL the same problems you did and did it this way.

-To get around the tight nuts and little time to adjust, I used the tool above.
-To get around the inconsistent leveling pressure from eyeballing it, I use the paper slip method that is popular with every other printer.
-I also had issues getting it all done in the initial time the head comes around, but quickly noticed I get more than one trip on the g-code. So, if you don’t get it perfectly on the first time, you’ll get another chance.

Sorry for the late reply. Thanks a lot for your tool, it’s really helpfull!

Just another question: How do you know when you need to do the tramming or that you did the tramming right?

The tramming process is pretty straight forward, being its very similar to manual bed leveling. The way I knew that I could benefit from a quick tramming, is the amount of movement of the Z-axis while printing. If your are printing in one section of the bed and it’s moving a fair bit up or down as it traverses a particular line, you might benefit from a quick tram.

In all honesty, its not likely going to change the performance too much, because the bed leveling will account for most slight tram issues, but I’d prefer to have it close and then let the bed leveling take over.
