AUTOMATIC CALIBRATION
For 3d printing the first layer is the most important layer, because it is the basis of a print job, which
sometimes can take 70+ hours to finish. An improperly printed first layer is mostly the cause of a failed
print. With the automatic calibration features properly executed, the chance of failure will be minimized.
11.1
What does the calibration do?
The FELIX Pro 1, is able to calibrate the following automatically.
-
Physically leveling the build plate. To ensure the distance between the bed and the nozzles is the same
over the whole build plate.
-
Detecting the height difference between the two hot-ends. To ensure when printing dual head prints
that the nozzles print at the same height. This is necessary, because the right print-head when rotated
to the front is by design lower than the left nozzle. Due to possible production tolerances, this distance
needs to be accurately calibrated.
11.2
When to calibrate?
We recommend to do the auto calibration in the following cases:
-
After replacing a hot-end.
-
After replacing a heated bed.
-
When the first layer is not sticking to the bed
-
When you see that the lines on the first layer, significantly differ in thickness.
-
When the printer leaves the factory everything is calibrated. Due to shipping, the chance is present
that the bed is not completely level anymore. So it is recommended to level the bed after unboxing
the printer. If you follow the quickstart guide, the first test-print contains the autoleveling routine.
The x, y distance between both hot-ends still needs to be done manually. (only necessary after changing a
hot-end and if you want to print in dual head mode). See chapter 12 for more information
The calibration mechanism is dependent upon the following features on the printer.
-
The build in probe-sensor in the hot-end.
-
The leveling gears underneath the bed.
When the auto bed leveling routine is started. The probe/hot-end will touch the bed at 4 points. After this
measurement the bed leveling gears will start to turn to make the bed level. (level in this case means that
the distance between the build plate and the hot-end is the same over the whole bed surface).
11.3
How to do the calibration?
We can start the calibration routines at the moment only by running specific print-files which are located
on the supplied SD card or can also be found on the website.
