# Ender3Pro_Firmware

Custom firmware for the Ender 3 Pro with BTT SKR Mini e3 v3.0, BLTouch, and Sprite Extruder Pro
1+
# Custom Ender 3 Pro Firmware using Marlin
2+
Please note this is a custom Marlin firewamre (Bugfix 2.1.x) that I made for my printer with parts listed below.
3+
4+
I have also included a precompiled version of the firmware based on Marlin Bugfix 2.1.X. Your milage may vary, install at your own risk.
5+
6+
I had to make edit to the pins_BTT_SKR_MINI_E3_V3_0.h file in order to get the fans and BLTouch probe working as intended. I will outline all my changes below
7+
8+
## Printer
9+
10+
- Ender 3 Pro
11+
- Big Tree Tech SKR Mini e3 v3.0 Control Board
12+
- Creality Sprite Extruder Pro
13+
- BLTouch
14+
15+
## Congifuration Edits
16+
17+
### Configuration.h
18+
19+
- #define BAUDRATE 250000
20+
- #define CUSTOM_MACHINE_NAME "Ender-3 Pro"
21+
- #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 424.9 }
22+
- #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN (Enable this)
23+
- #define USE_PROBE_FOR_Z_HOMING (Enable this)
24+
- #define Z_MIN_PROBE_PIN PC14 (Enable this and set for pin of SKR Mini e3)
25+
- #define BLTOUCH (Enable this)
26+
- #define NOZZLE_TO_PROBE_OFFSET { -36.5, -40, 0 }
27+
- #define XY_PROBE_FEEDRATE (10000)
28+
- //#define MIN_SOFTWARE_ENDSTOP_Z
29+
- //#define MAX_SOFTWARE_ENDSTOP_Z
30+
- #define AUTO_BED_LEVELING_BILINEAR (Enable this, disable others)
31+
- #define HOMING_FEEDRATE_MM_M { (40*60), (40*60), (8*60) }
32+
- #define GRID_MAX_POINTS_X 3
33+
- #define Z_SAFE_HOMING
34+
35+
36+
### Configuration_adv.h
37+
- #define CONTROLLER_FAN_PIN FAN2_PIN
38+
- #define CONTROLLER_FAN2_PIN FAN1_PIN
39+
- #define PROBE_OFFSET_WIZARD
40+
- #define FILAMENT_CHANGE_UNLOAD_LENGTH 50
41+
- #define FILAMENT_CHANGE_FAST_LOAD_LENGTH 50
42+
- #define ADVANCED_PAUSE_PURGE_LENGTH 10
43+
44+
45+
### pins_BTT_SKR_MINI_E3_V3_0.h
46+
47+
I had to change the Z_STOP_PIN since I don't have a physical Z-Stop anymore. I would run into a weird error where when the printer wanted to home itself X and Y worked, and the Probe on the BLTouch would Extend and Retract a few times before the printer just said `STOPPED`
48+
49+
- #define Z_STOP_PIN PC14 // Z-STOP
50+
51+
52+
## Fan Layout
53+
54+
- Fan under the printer on the SKR Mini - FAN1 (PC7)
55+
- Fan on the Sprite Pro - FAN2 (PB15)
56+
- Parts Cooling Fan - FAN0 (PC6)
