Exact Z height ?


Recommended Posts

Posted · Exact Z height ?

I'm so newbie , i'll ordered um2. I read manual of ultimaker and cura and i have some questions.

Using paper for calibration is no looks so afforable i guess

I have Z height gauge which i used to set tool height in my DIY CNC.


This tool has exact height (50mm) it has very accurate 0.01mm. If posibility to set Z height coordinate manually ( to -50mm after zeroing )

And other question is what is the proper height in mm ?

And here is the paper gauge chart.

I believe the proper height is .1mm.

After you perform the leveling procedure once I recommend you never do it again and do more accurate leveling as needed by simply turning the screws small amounts when you want extra precise leveling. You level by printing the skirt or brim of your object and if the brim is too thin or too thick you adjust the screws.

    You can level very precise but the exact height still depends on the nozzle temperature as well. With temperature the nozzle expands. That is why the piece of paper (0.1mm) room must be there so that at print temperature the nozzle touches the bed. So your tool is probably too exact for this. I guess your CNC machine does not have that temperature limitation.

        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
