This small blog-post guide can be used with any printer using the standard Gcode system.
I’m simply writing it in regards to Ultimaker as the issue has arisen from using these machines and their special kind of bed adjustment, which doesn’t provide any tools to do fine final adjustments.
Go to their website and download the program for your system. File downloads for Windows, Linux and MAC.
You can also go and visit their Github repository if you want to.
After installation you select proper Com port and Baud if/as needed and hit Connect.
When you connect you automatically get a detailed readout of current settings.
I’ve noted the Extruder steps/mm as many would like to adjust these some.
The current Z-offset as defined during setup of myUltimaker is Z-12.45. The nozzle needs to be a tad closer to the bed, so I’ll change the Z-offset to Z-12.40 as raising number is closing in the distance, while lowering the number increase the distance.
We are using M206: Offset Axes to change the Z-offset.
We simply type M206 followed by the new value of Z-12.40
Now use M500 to save the new settings to Eeprom in order for the changes to be in place after poweroff.
It will all look like this in Pronterface serial window:
Reconnect to verify changes are now changed. Might want to unplug USB and power the printer on and off to verify the changes are stored correctly as well.
