Chiron Mod Pack
Description
This mod pack is a (functional) WORK IN PROGRESS that currently contains: X-carriage with quick swappable tool head Frame stabilizer with z-screw anti-wobble Motherboard enclosure for SKR 2.0 PSU cover ------------------------------------------------------------------------------------------------------------------------ IMPORTANT NOTES: The included x-carriage is currently only compatible with sensorless homing. The frame stabilizer lowers the height the printer sits off of the ground. The stock motherboard enclosure and PSU WILL NOT FIT under the printer anymore with this mod in its default configuration and must be placed elsewhere. ------------------------------------------------------------------------------------------------------------------------ INTRODUCTION This is my first major project and was not originally planned for release to the public. I have no background in engineering or mechanical design and my parts may not be 100% perfect. I decided to upload this anyway because I felt that they offered an improvement over what's out there. This project is not complete and revisions will most likely be provided in the future. This project is moderately difficult and may not be ideal for someone brand new to printing (until I am able to make up an install guide). I would appreciate any and all feedback and suggestions for the future! ------------------------------------------------------------------------------------------------------------------------ X-CARRIAGE NOTES This carriage mounts directly onto the original chiron mounting plate and replaces all of the other original hotend parts. The carriage is designed to allow you to quickly switch between tool ends. In this pack you will find mounts for a standard e3dv6 and a generic laser engraver that plugs into the parts fan header on the hotend pcb. This was designed to be modular, so creating different mount plates for other hotends or tools (bigger laser, marker holder, cutter, spindle, etc...) shouldn't be difficult. The parts cooling fan is also meant to modular so you can swap out for other sized fans if you feel like designing the part. You will need a variety of M3 screws to complete this assembly. I would recommend buying a set of M3 screws in various lengths. You should be able to find one for about $10 USD. I don't know what screw lengths I actually used, I just grabbed whatever ones fit. You will also need a 40x10 fan and a 50x15 blower. You will want to print the parts cooling fan in either ABS or PETG. Due to its proximity to the hotend and the bed I assume it will get too hot for PLA. Despite being only a couple millimeters from the heatblock, PETG has held up just fine for me for over 100 hours of print time at 260/90. There are 2 screws that go through the parts fan duct piece to hold it in place. These are the same diameter as the screws that hold the endstop switch in place. I believe they are 2.5mm but to be honest I haven't checked this since I don't actually use them. The duct should fit tight enough that these screws aren't really necessary. The new z-axis endstop triggers things will necessary to home to the right location. BLtouch offset is (35.5, 8, -1.1) As previously mentioned, this currently only works with sensorless homing. In the future I plan to design a belt tensioner that will hold the x endstop but I havent had time to yet. Stay tuned. ------------------------------------------------------------------------------------------------------------------------ FRAME STABILIZER NOTES This frame stabilizer is a relatively straightforward print and install. It is designed to accommodate either 3/8" or 10mm threaded rod (although I don't have any 10mm rod to do a test fitting). As previously mentioned, the motherboard enclosure and the PSU will need to be relocated to run this mod in its current state. They may still fit if you install longer "feet" onto the parts. I tossed out the original motherboard enclosure piece so I can't verify that. At the bottom of the bottom frame corner pieces are holes to accommodate 1/4" nuts and bolts. These are so you can add some sort of TPU feet to the print for vibration dampening. I intend to design these feet at a later date. The pieces for the top of the frame reuse the bearings from the original z-screw holder thing. Don't toss out the screws that hold the frame together, these are still necessary. ------------------------------------------------------------------------------------------------------------------------ MOTHERBOARD ENCLOSURE This enclosure is designed for the SKR 2.0. It may fit other BTT motherboards but I haven't checked. The fan mount is designed to fit the original motherboard cooling fan (whatever size that is). This enclosure is also designed to fit the original chiron mini PCB thing that goes to the hotend (the one with the red plug that the wiring harness plugs into) as well as the original chiron bed mosfet. The dovetails on the sides are there for future mounting options (yet to be designed). As of right now, it just sits beside the printer. Also planned for the future is a new lid for this enclosure that will hold a TFT35. ------------------------------------------------------------------------------------------------------------------------ PSU COVER This is a simple cover that bolts onto the PSU to keep the terminals covered up and safe. It is also designed to reuse the original chiron main power switch assembly. Unplug your printer from the wall before installing. I will likely redesign this later on to incorporate the same dovetail mounts that are present on the motherboard enclosure for ease of mounting. ------------------------------------------------------------------------------------------------------------------------ END NOTES All CAD files are included in this pack so feel free to remix this to your hearts content! If you do remix this, all I ask is that you credit me for the initial design work. I plan to update this as I make more progress, but when that will be is hard to say. I plan to include my Marlin configuration later on to make swapping to the SKR 2.0 easier. Once again, ALL FEEDBACK (good or bad) IS APPRECIATED! ------------------------------------------------------------------------------------------------------------------------ Liability disclaimer: I take no liability for any damages, injury, death or other bad things that may happen during your installation of these mods. Install at your own risk.
