MBL test pattern
With the MBL-test-pattern you should be able to see how good MBL is working. All 9 pieces should have the same layer adhesion as well surface finish.
This test should be also show if a new firmware still does the job or got better or even worse. it makes sense to redo this after a firmware update.
With the First layer calibration you should have the "perfect" Live-Z. But it may be different for the center, so please follow these instruction:
- Write down the 1st layer cal value you are using.
- Open the attached
MBL-test-pattern.3mf
file in PrusaSlicer and set your Printing (0.2mm Speed or Quality), Filament and Printer settings to the material and printer you are using. - remove all edge patterns
a_
toh_HyperCal.stl
so you just have thecenter_HyperCal.stl
left on build plate. - Slice it and export the gcode.
- Clean the bed.
- Print the
center_HyperCal
if the print looks good / perfect continue with MBL-test-pattern-
Redo this print and adjust the Live-Z until you are happy with the result and write down the Live-Z value for the center print.
Don't forget to clean the bed each time.

- Open the attached
MBL-test-pattern.3mf
file in PrusaSlicer and set your Printing (0.2mm Speed or Quality), Filament and Printer settings to the material and printer you are using. - Slice it and export the gcode.
- Clean the bed
- Print the whole pattern.
If MBL is working fine all 9 test pattern prints should have the same good adhesion and surface finish.
If they are not you can focus to print one by one that aren't good:
- Connect your printer via USB to Pronterface/Octoprint
- Run
G80
command and after thatG81
- Copy/save the
G81
results for later.
- Copy/save the
- Open the attached
MBL-test-pattern.3mf
file in PrusaSlicer and set your Printing (0.2mm Speed or Quality), Filament and Printer settings to the material and printer you are using. - remove all except the **one **you want to fine tune / do research on, so you just have ONE left on build plate.
- Slice it and export the gcode.
- Clean the bed
- During printing the one pattern try to fine adjust the Live-Z so it looks "perfect" / equal to the center print.
-
Redo this print until you are happy with the result and write down the Live-Z value for that print.
Don't forget to clean the bed each time.

If you want to report back your results, please add at least following information:
- Printer: MK2.5, MK2.5s, MK3, MK3s
- MMU: MMU1, MMU2, MMU2s
- Firmware version printer and MMU
- Live-Z found via 1st layer cal.
- Live-Z value for the
center_HyperCal
print. - Live-Z values for other pattern prints that needed adjustment.
- Add
G81
results.
