## Printer: Artillery Genius
- build size 220\*220\*250 mm
- direct drive
- bed max temperature 130C
- hot end
  - 24V, kraken heatbreak, e3d volcano nozzle & block, nt100 thermistor

## Current mods/software in use
### Hardware
- Raspberry Pi 3 Model B Rev 1.2
- 3DTouch leveling sensor
- mellow/trianglelab nozzle
- full-metal heatbreak
- Bigtreetech TMC2209 v1.2 stepper drivers, in uart mode
  - [A guide for uart mode by @Dan;#1256](https://docs.google.com/document/d/1MyUdEjQ_6hr7yFaBdw0NXcICgTD9j5_0CI363yzLEuU/edit)
- Energetic flexible spring steel & PEI sheet
- ADXL345 accelerometer, (https://www.klipper3d.org/Measuring_Resonances.html)
- At some point, maybe:
  - Improvements for Z-banding: miagi, cobra
  - Aluminium bed

  - old ones:
    - bed cable strain relief, (https://www.prusaprinters.org/prints/55642-genius-zx-adjustable-bed-cable-strain-relief)

### Software
- [Klipper](https://www.klipper3d.org/Overview.html)
  - pressure advance, input shaping, auto bed leveling
  - [Clank's config used as the base](https://github.com/Clank50AE/Clanks-Klipper-Configs)
  - both [Mainsail](https://docs.mainsail.xyz/) and Fluidd installed
- [SuperSlicer](https://github.com/supermerill/SuperSlicer/releases)


## Leveling process
- heat up the bed and wait for a few minutes
- `PROBE_CALIBRATE`
- take A5 sized copy paper
- close the gap between the nozzle: `TESTZ Z=-.1` with smaller and smaller increments
- leveling is done when you can still move the paper by pulling, but it curls up when pushed
- `ACCEPT` and `SAVE_CONFIG` to save the values

## Replacement parts
- nozzle: volcano
  - aliexpress: trianglelabs or mellow
- heat block: volcano
- heatbreak
  - if the cooler plate has two holes: smooth heatbreak, "kraken" style

## Printing with PETG
- spread gluestick to bed, dilute with water if needed
- increase the gap between nozzle and bed a bit
- bed temperature: first layer 80C, others 70C (ie 10C warmer than with PLA)
- nozzle temperature >230C
- decrease part cooling

## Misc tips
- [Tape out the 5V line from Pi to mainboard](https://community.octoprint.org/t/put-tape-on-the-5v-pin-why-and-how/13574)
- Detach the 2-wired reset connector between TFT and mainboard: when flashing (Marlin) firmware, keep the reset button pressed to keep the TFT off
- After changing nozzle/hotend
  - Heat up to 230C, loosen nozzle, tighten heat block, tighten nozzle
  - PROBE\_CALIBRATE, TESTZ Z=-1 etc, ACCEPT, SAVE\_CONFIG
  - PID\_CALIBRATE HEATER=extruder TARGET=200, if needed, with fan on
  - heat up the bed and G29
