Calibrating problem in heigth

Recommended Posts

Hello guys,

i'm quite new to 3D printing world, i've just bought an UMO+ and build it. But i'm already facing problems that makes impossible for me to print anything. I precise i THINK there's no assemblage problem.

Here are my two problems :

-when i try to calibrate the plate's heigth with Cura, the plate always goes down no matter on which button (Up or Down) i click. I try this with different versions : 15.04.2, 15.04, 15.01, 14.12, 14.09. No one worked correctly. But i can move it down and up with the controller. You can find a video of the problem here :

-my second issue is that when i use "Auto home" function, my printer made this good, but when i start printing something, the plate goes down, and it starts printing with 36mm too much heigth, so the plastic falls from too high. When this happens, i see "Z = 0" on the controller, and when i stop it and use the "Auto home" function, it now indicates me "Z = - 35.09" (which is the anormal distance between the plate and the printer's head). This is always the same distance no matter the heigth of what i print. You cand find a video of the issue here :

I've already post a message on the french community, but in order to be read by more people i also post here.

Thanks in advance for helping me solve this issue!

Yeah this sounds very close (if not exactly the same). I'm in contact with Makershop, is that the right way to get another panel if it is the real cause of my issue? Or should i contact directly Ultimaker staff?

About the settings and firmware, i always create a new machine and update firmware before every test.

I suppose that (I'm really not sure) you could disconnect the panel and print by usb. Usb printing can give problems since usb can have power changes, but for the purpose of the test you could send the gcode by cura usb with the panel disconnected and see if it makes the same error or it doesn't.

      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.
