Modelo 3D RatRig VCore 3 Tool Changer por psyvision no Printables

Descrição

About

This is a tool changer modification for the RatRig VCore 3 printer that utilises an E3D style coupling.

Belts

This modifications is designed with the intention of being used on an VCore 3 with the so called “OpenFront” modifications where an alternative location exists for tensioning the printer belts.

Z-Probe

This modification is designed with the intention of using the z-probe mounts (or similar) used with the EVA system and specifically a SuperPINDA.  I will possibly design an alternative mount using a SPDT endstop type switch.

X-Endstop

This modification uses the blank EVA MGN12 top and therefore EVA X-endstop mounts can be reused.

Y-Endstop

This modification moves the Y-endstop to the front of the frame - once tested I will attach an STL.

 

Demo

 

Upcoming Enhancements

CAN Board Mounts

I am currently testing alternative extruder mounts that can fit 36 size CAN boards, e.g. BTT EBB36.

Heat Insert Sizing

I am investigating increasing heat insert chamfer from 0.5mm to 1.0mm to create a better fit.

Dock Improvements

I am going to implement some screw holes to retain the docking pins as I have had one pin start sliding out when un-docking tools.

Stepper Motor: This build assumes the usage of the motor although I have trialled and used a 24BYJ-48 (available from Mouser and RS Components) which seems to work well too. I can provide alternative parts for this if required. 

Spring: I purchased a 20mm spring initially which was too long and I cut it down, the 10mm I have is slightly too short so would recommend a 15mm or 20mm and cut if required.

Note: This is for a single tool dock.

Tools

Helical Lock Ramp: This can be 3D printed (TC - Tool - Ramp.stl) and I would recommend 0.1mm layer height or less.

 

Tool v2

BOM coming soon.

This tool is a modular tool which:

  • Enables easier changing of parts (e.g. swap a hotend or extruder easily)
  • Easier printing
  • Better airflow for inward facing 5015

Software Configuration

The configuration here presumes the usage of Klipper - Duet is not covered.

Plugin Installation

Install this excellent Klipper plugin by Andrei Ignat - [https://github.com/TypQxQ/Klipper_ToolChanger](https://github.com/TypQxQ/Klipper_ToolChanger)

Klipper Configuration

I have uploaded my RatOS configuration folder to the following repository:

[https://github.com/psyvision/vcore3-configuration](https://github.com/psyvision/vcore3-configuration)

This is mostly typical RatOS configuration and the tool changer configuration is in the “additions” folder:

File / FolderPurpose
coupler.cfgConfiguration and macros relating to the tool head coupler
dropoff.cfgMacros relating to dropping tools onto docks
pickup.cfgMacros relating to picking up tools from docks
tX.cfgConfiguration relating to individual tools
toolchanger.cfgToolChanger Klipper plugin configuration
tools.cfgToolChanger Klipper plugin tool configuration

speed-limits-performance.cfg

steppers.cfg

tmc2209-performance.cfg

These files provide the same functionality/configuration as the original RatOS configuration except removing the extruder configuration
