Ultimaker 1(Original) Z plate not level

Recommended Posts

Your build plate should not be level (as compared to ocean level) but parallel to the axes your print head travels along.

So: If you print constant thicknesses throughout the print area, your leveling is as it should be, no matter at what angle it rests compared to sea level.

As long as you can level it using the screws I wouldn't worry about it really. I know my plate had a dip in the front left corner so that I had to unscrew that particular screw quite a bit. But it has printed just fine for a couple of years in that state. So, as long as you can get the print bed level I'd just crank on with the build :)

Right, i had not taken into consideration that you are still assembling. Sorry for that.

As soon as you have mounted your print head you can easily see if, using the levelling screws, you can or cannot adjust the build plate so that you get equal distances from the bed to the nozzle throughout the area.

If your build plate is not flat (i.e. bent, corrugated, twisted), you do in fact have a problem, but i guess you did not mean that?

Perfectionist is good, stick with that!

And much fun with your printer!

Nothing needs to be level. You can hang the printer by a rope to one corner upside down and it will print fine.

When we talk about "leveling" what we really mean is that as the nozzle is pushed around to the 4 corners it should be EXACTLY the same distance from the build plate - that acrylic flat piece. Well not "exactly" but .01mm would be nice which is 1/10 the width of a piece of paper.

Unfortunately wood warps over time (plus humidity affects it) so you have to level the UM Original quite often - maybe every few hours the first few weeks. Fortunately the heated bed upgrade has no wood parts (still in alpha test - hopefully it will be available within a few months).

Well I'm used to the 3D printing world. i just had a Prusa i3, but decided to go the Ultimaker way.

And i know that i could hang it with a robe and it should still work.

But the problem i just had was that the build plate was not very level to the rest of the printer.

i sort of fixed it (still not satisfied). but i turned the build plate 180 degrees, that helped.

i think the wood is a little bend.

but ill definitely gonna ask sooner or later about leveling the nozzle to bed. Because on the i3 i had i couldn't get any good prints. because of nozzle height and x carriage wasn't linear.

Maybe ill develop another z build plate later on, but for now ill have to live with what i have.

Profile updated ! :D

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
