# Jafo 3 Pro

An Ender 3 Pro upgraded with:

- SKR Mini E3 V2.0

- Creality Sprite Hotend/Extruder

- CR-Touch

- X and Y steppers upgraded with "Usongshine Nema 17 Stepper Motor 42BYGH 1.8 Degree 38MM 1.5A 42 Motor (17HS4401S)"

This repo includes a Klipper config for this printer.

## Why

It was mostly about wanting to get auto bed leveling on the Ender 3 Pro.

My steppers had started losing steps, and I couldn't find any issues in

the X/Y travel or belts, and the steppers were already at a reasonable

voltage, and were running warm, so I replaced them and the level shifting

stopped.

## Start/End G-Code

Start G-Code needs to be:

```

; Ender 3 Custom Start G-code

G92 E0 ; Reset Extruder

G28 ; Home all axes

BED_MESH_CALIBRATE

BED_MESH_PROFILE SAVE=p1

G1 X0 Y0 Z5 F4000

;G29 ; Auto Bed Level with BL-Touch

;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

```

And End G-Code:

```

G91 ;Relative positioning

G1 E-2 F2700 ;Retract a bit

G1 E-2 Z0.2 F2400 ;Retract and raise Z

G1 X5 Y5 F3000 ;Wipe out

G1 Z10 ;Raise Z more

G90 ;Absolute positioning
