The bed calibration
Before the first print it is needed to calibrate the bed and to align its plane relatively to the extruder motion
plane. To change the position of the bed work surface 3 milled nuts are intended. One of them is located in
the center of table edge, 2 others - at the corners of the table at the bottom.
To calibrate the bed connect to the printer using Repetier-Host (as described in previous sections), go to
the Manual control tab and insert in the command line:
M190 S60
M109 S210
Turn on the heating of the bed and extruder. To send the commands press the button “Enter” after every of
the command. Screw bed adjusting screws until tight. After the bed and extruder heat up, insert the next
commands:
G28
G1 Y145 Z0
The printing head will move and take a position above the first adjusting screw. Turn the screw till the
moment when the bed will touch slightly the end of the nozzle.
Then insert the commands:
G28
G1 X100 Y0
The printing head will take a position above the second adjusting screw. Repeat the same actions as with
first screw.
The next commands block:
G28
G1 X-100
