9 in 1 Temperature First Layer Calibration Matrix - 3x Bed and 3x Nozzle temperatures in one print

What it does:

Prints 9 tiles, each with a different bed and different nozzle temperature.  I basically vary these two temperature settings:

Note: PrusaSlicer v2.6.0-alpha6 or higher is required!  

Not tested on Orca or Bambu slicers

I was struggling to get that perfect first layer using a new type of filament.  After countless calibrations I still was not happy.  In the end, my issue was a combination of temperature, layer height and extrusion multiplier.

During this process I developed this custom G-Code macro to test 9 different temperature combinations in one print.  For those of you who have never heard of this, the macros are essentially code which can adjust your G-code during slicing.

How to Use This Macro:

There are two customer G-Code entries in this file

Printer Settings → Custom G-code → Between objects G-code:

{local SJB_BedTempStepSize = 10 }. ; Step size to change the bed temperature (+ / - )
{local SJB_NozzleTempStepSize = 8 }. ; Step size to change the nozzle temperature (+ / - )

These are the two variables you need to adjust.  

SJB_BedTempStepSize = 10

This is the temperature step size to vary your bed temperature from the default value.  For example, if your first layer bed temperature is 85°C, and SJB_BedTempStepSize = 10 is set to 10, then the three resulting bed temperatures will be 75°C, 85°C, and 95°C.

SJB_NozzleTempStepSize = 8

This is the temperature step size to vary your nozzle temperature from the default value.  For example, if your first layer nozzle temperature is 240°C, and SJB_NozzleTempStepSize = 8 is set to 8, then the three resulting nozzle temperatures will be 232°C, 240°C, and 248°C.

Printer Settings → Custom G-code → End G-Code: (optional)

This is just some optional G-code to produce lines on top of the tiles.  This keeps them together when you take them off the bed.

Tips:

Raise your Z-offset up around 0.1-0.2mm.  When you have a perfect first layer already, the difference between the tiles is very difficult to see.  The differences are more evident when the first layer is a little higher than it should be.  This also makes the rip-test easier, where you can try to rip the tiles in half along the seam lines.

How it works:

This slicer model uses the new custom variables which were released in PrusaSlicer v2.6.0-alpha6. (Link: https://github.com/prusa3d/PrusaSlicer/wiki/PrusaSlicer-Macro-Language)

and

sequential object printing.  So after every object (tile), the g-code is changed and the temperatures are modified.

Happy Printing!
