Printer calibration
For 3d printing, the first layer is the most important layer. It is the basis of a print job (which can take more than 70
hours in some cases). 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.
The calibration mechanism is dependent upon the following features on the printer.
-
The probe sensor in each hot-end.
-
The leveling gears underneath the bed.
So, when one of the above two systems is not working properly, the printer will not be able to calibrate.
What does the calibration do?
For the FELIX Pro 2 to properly operate the calibrations described in this chapter need to be performed.
7.1.1
Physically leveling the build plate. (automated)
To ensure the distance between the bed and the nozzles is the same over the whole build plate. This is done
automatically.
When to do this calibration?
-
When changing to a new 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 from one side to the other side of
the build plate.
-
After transporting the printer.
When the auto bed leveling routine is started. The following steps are performed.
1.
The hot-ends heat up to 185
˚C
2.
The currently active extruder will touch the bed at 4 points.
3.
The bed leveling gears 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).
4.
The probe/hot-end will touch the bed at 4 points to verify. If ok, the calibration is done, if not ok, the routine
goes back to step 2. This loop will be done max 5 times, but when the machine is in proper condition it should
take max 3 cycles.
How to do the bed leveling calibration?
Please consult the quick start manual for further instructions.
7.1.2
Z-height calibration, detecting the height difference between the two hot-ends. (automated)
The extruders must operate at the same height. Due to production tolerances and rotating mechanism of the right
extruder, this has to be calibrated. The printer will do this in an automated way.
When to do this calibration?
-
After changing one of the two hot-ends or nozzles.
-
When you see the first purge lines are significantly different in thickness.
The extruder height calibration routine performs the following:
