# Einsy Rambo Config for Průša MK3S
|
|
|
|
## Requirements
|
|
- [Průša MK3S, MK3S+, or MK3 with MK3S/MK3S+ upgrade](https://www.prusa3d.com/original-prusa-i3-mk3/) is required for filament runout to work properly.
|
|
- Stock Einsy Rambo with integrated TMC2130s
|
|
|
|
## Configuration Options
|
|
|
|
Flags specific to this printer/configuration:
|
|
|
|
- `MK3_FAN_PINS` - Disable this for `FAN0_PIN 8` and `FAN1_PIN 6`
|
|
- `GEARBOX_BEAR` - Is printer equipped with a 3.5:1 gearbox on the extruder?
|
|
- `LOWBAUD` - Printer needs lower baudrate?
|
|
- `TALLBEAR` - Tall Bear (320mm)?
|
|
- `SUPERPINDA` - SuperPinda present?
|
|
|
|
## Changes to Start G-code
|
|
The `W` in Průša's `G28 W ; home all without mesh bed level` default G-code does not exist in Marlin and [`G80 ; mesh bed leveling`](https://marlinfw.org/docs/gcode/G080.html) cancels the current motion mode, so no bed leveling will take place.
|
|
|
|
Below are some example start G-code scripts from popular slicers to get you started.
|
|
|
|
### PrusaSlicer
|
|
- Set your G-code flavor to "Marlin 2" under "Printer Settings" -> "General" -> "Firmware" -> "G-code flavor".
|
|
- Use the "Custom G-code" section under "Filament Settings" to add the [Linear Advance](https://marlinfw.org/docs/features/lin_advance.html) (`M900 K0.0`) value since it can be saved on a per-filament basis.
|
|
- Paste the start G-code block below in the "Custom G-code" section under "Printer Settings".
|
|
|
|
```gcode
|
|
G90 ; use absolute coordinates
|
|
M83 ; extruder relative mode
|
|
M104 S170 ; preheat hotend to 170
|
|
M140 S[first_layer_bed_temperature] ; set bed temp
|
|
M190 S[first_layer_bed_temperature] ; wait for bed temp
|
|
G28 ; home all
|
|
G29 ; mesh bed leveling
|
|
G1 X0 Z0.6 Y-3.0 F1000.0 ; go outside print area for intro line
|
|
M104 S[first_layer_temperature] ; set hotend temp
|
|
M109 S[first_layer_temperature] ; wait for hotend temp
|
|
G92 E0.0
