Ender3Pro_2.4.7_Marlin

My configuration used to compile Marlin firmware for my Creality Ender-3 Pro, with 2.4.7 controler board and BLTouch.

Marlin version

This is the Marlin 2.1.2.1 version, using UBL bed leveling.

The machine

• Creality Ender 3 Pro, with Creality 4.2.7 board.
• BL Touch connected on the board dedicated port (Not on the Z-limit switch).

I compile it using platform io with the STM32F103RE_creality 256K flavor.

How to compile

You must copy the config files into the Marlin subrepo. To do this use the prepare.sh script, or drop the four files in config (_Bootscreen.h, _Statusscreen.h, Configuration_adv.h and Configuration.h) into Marlin folder.

See https://marlinfw.org/docs/basics/auto_build_marlin.html for more information on the build process.

Using UBL leveling

Use the following g-code in Cura to start printing

; Ender 3 Custom Start G-code
G92 E0 ; Reset Extruder
M104 S{material_standby_temperature} ; Start heating up the nozzle most of the way
M190 S{material_bed_temperature_layer_0} ; Start heating the bed, wait until target temperature reached
M109 S{material_print_temperature_layer_0} ; Finish heating the nozzle
G28 ; Home all axes
; UBL - start
G29 L0 ; Load UBL from slot 0
G29 J ; Probe 3 points and tilt the mesh to the plane
; UBL - end
G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed
G1 X0.1 Y20 Z0.3 F5000.0 ; Move to start position
G1 X0.1 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line
G1 X0.4 Y200.0 Z0.3 F5000.0 ; Move to side a little
G1 X0.4 Y20 Z0.3 F1500.0 E30 ; Draw the second line
G92 E0 ; Reset Extruder
G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed
G1 X5 Y20 Z0.3 F5000.0 ; Move over to prevent blob squish
