V# V-Core IDEX for RatOS 2.X This is a unofficial and temporary RatOS V2.X IDEX Implementation. Consider it as beta or alpha. Macros are based on Mikkel Schmidt`s work and have been modified and extended by Helge Keck.

PLEASE NOTE NEW VAOC MAINSAIL SOURCE CODE CHANGES!

merged with latest mainsail version
works only with the new RatOS Development Branch for the upcoming RatOS 2.1 version
you need to use the new post processor module which is available in the devlopment branch

Hardware

Left toolhead MUST be the X toolhead
Right toolhead MUST be the Dual Carriage toolhead
Name your extruders extruder left and extruder1 right
Name your toolboards toolboard left and toolboardb right
Name your toolboard adxl adxl345 toolboard left and adxl345 toolboardb right
Name your part cooling fans fan_generic fan_extruder left and fan_generic fan_extruder1 right
make sure the nozzle from the z-probe toolhead is NOT higher then the other nozzle, ideally they have the same z-offset
place the X and DUAL_CARRIAGE endstop stoppers as much outside as possible, to their max positions where they still work
tune the X and DUAL_CARRIAGE endstop_position values to its correct positions
your toolhead offsets should be less than 1mm
if T1 is primary, make sure T0 has a positive x offset, and reverse

Install RatOS IDEX

install RatOS for V-Core 3
update klipper
clone the idex repo

cd ~/
git clone https://github.com/HelgeKeck/vcore-idex.git
bash ~/vcore-idex/install.sh

add the update manager entry to the moonraker.conf file in your config folder

[update_manager IDEX]
type: git_repo
primary_branch: main
path: ~/vcore-idex
origin: https://github.com/HelgeKeck/vcore-idex.git
managed_services:
	klipper

reboot, not your laptop

Inverted Hybrid CoreXY Kinematics

add this to your printer.cfg

[hybrid_corexy]
inverted: true

IDEX modes

by default the printer will be in single toolhead mode.
to enable the Copy or Mirror mode for the next print, home your printer and then execute the IDEX_COPY or IDEX_MIRROR GCODE macro.
execute IDEX_SINGLE to switch back to normal mode.

G-Code Macros:

Toolchange configuration

ZHOP Z-Hop before and after the toolchange, in addition to the slicer z-hop
COMBINED_ZHOP 0=OFF 1=ON. Combines z-hop/z-drop with retraction/deretraction moves
M400 0=OFF 1=ON. Turn M400, for the z-hops and z-drops, on or off
RETRACT Retraction before the toolchange
EXTRUDE Extrusion after the toolchange
FEEDRATE Feedrate for retract/extrude
SPEED XY Travel Speed
ACCEL XY Travel Accel
SYNC_FANS 0=OFF 1=ON. Forces fan synchronisation in single mode. Helpful because the new ultra fast toolchanges can be MUCH faster than your part cooling fan spin up time. TIP! The Sanyo Denki 9GAX0412P3S001 4028 is almost as fast as the toolchanges

G-Code Macro:

IDEX_CONFIG

Manual toolhead offset calibration

for the X and Y calibration use the calibrate_separation macro to print the calibration lines, you are responsible for heating up your bed and extruders, dont forget to z-tilt and the bed mesh
use the SET_SEPARATION macro to enter your toolhead offsets from the left toolhead

X=1 to set the x-offset to 1
X_ADJUST=1 to add 1 to the current x-offset
X_ADJUST=-1 to subtract 1 from the current x-offset
