8.2 PINDA probe calibration/ Temp. calibration (Experimental/Optional)
It is still an experimental feature available since firmware version 3.0.12. Each user has the
option to turn this feature on and off, as it may not help out in all of the cases. Once you
decide to use this feature, be aware that there is a shorter calibration run before each of your
prints compensating for different temperatures (this adds about 2 minutes to the standard
preheat process).
New PINDA probe calibration is minimizing the issue of frequent re-doing of your Live Z
adjust. That can occur once your PINDA probe readings are influenced by surrounding
conditions, mostly different temperatures. This can happen if your Live Z was tuned once
printing PLA and later on you print ABS or the other way round as the bed temperature is
very different.
To use this new feature it is necessary to run the temperature calibration first. It can be
found in
​ Calibration - Temp. calibration - Calibrate ​ . Before you do so, please make sure
that your nozzle and heatbed are perfectly clean as the extruder will be moving around
heatbed during this process.
Do not touch the nozzle or heatbed during this process until it is fully finished as it
will reach high temperatures!
Once calibrating your PINDA probe, it will be comparing its data readings under different
temperatures and also on top of that it will include your Live Z data. This should help you to
have stable Live Z.
Still make sure that your 1st layer is done properly. More about that in
​ 6.3.10.
Fine-tuning the first layer
8.3 View XYZ calibration details (Optional)
Since the release of firmware version 3.0.12, you have an access to more detailed info about
XYZ calibrating results. This new feature can be found in
​ Support - XYZ cal. details ​ . The
1st screen tells you the distance of the “perfect” position of your front 1st, 2nd and 3rd
calibration points. Ideally, all of these are positive and at least 0.5 mm or more. If the margin
is between 0 and 0.4 mm, then there is a chance that your calibration will not work all of the
time. In order to improve your results, you shall move with your threaded rods so that all of
the points are reachable.
​ When you get your axes perpendicular or slightly skewed,
nothing needs to be tweaked as printer will perform with the best accuracy ​ .
