Welcome to my 3d Printer Setup Page
What you find
You will find informaion about my efforts to handle and calibrate my anycubic mega x 3d printer.
How to Calibrate the Printer
Heat Tower
You need a heat tower to find the best temperature for your printings. It’s quite easy to build a heat tower with Heat Tower on Thingiverse. Cura has a Plugin in
` Extensions -> Post Processing -> Modify Gcode `
There you have to add a script and use the ChangeAtZ Script.

Extruder Steps
To calibrate your extruder, you have to extrude filament with the hotend. Therefore you have to measure the filament before the extruder and extrude a specific amount of material. The printer should be heated so you don’t damage your printer. After that you measure again what is left of the filament. The difference can be used to calibrate the esteps of the extruder
Gcode to set extruder to relative mode
M83
Gcode to extract 10 mm filament with speed of 100
G1 E10 F100
Gcode to get the information of the esteps
M503
Search for M92
And take the last value of the esteps
Formula for the the new extruder config
new_steps = wanted_extrusion / real_extrusion * current_steps
Gcode to configure the extruder
M92 Enew_steps
Z offset
Fillament thickness
Extrusion multiplyer / Flowrate
It’s quite easy you just print a cube with one layer without top and bottom with a specific width. Take 0,45 mm width for it. Then measure all five walls and take the mean of it.
extrusion_multiplyer = 0.45 / mean_value
