<h1>Anycubic i3 Mega X-Carriage</h1> <h2>MK4 - e3d v5 & v6 Version</h2> --- <b>This is the new generation (MK4) of the previous MK3 design of my famous <u>free-to-use</u> X-Carriage for the Anycubic I3 Mega (S)</b> The MK4-Design was completely re-designed from scratch for most parts to gain more flexibility and a better user experience. Thanks to all supporters of this project & their suggestions/ideas for new stuff which I took for improvements of this new generation of the Carriage! --- The whole MK3 project is included in the MK4 project folder which can be downloaded here. --- If you enjoyed this project please share your <u>Make</u>, leave a <u>Like</u> and <u>Collect</u> for the community. <b>To show your acknowledgment and support for my large Effort on this you can donate via [PayPal](https://www.paypal.me/MartinL3d)</b> --- <h2>The main design features:</h2> - e3d v5 & v6 hotends are supported - Fully new X-Carriage with better & more flexible bearing holding system - Faster Hotend change due to improved Carriage system - Less weight compared to MK2 & MK3 (mainly due to weight reduction of the mandatory fasteners) - Increased build volume in z direction (205-210mm) - Extremely effective belt tensioners included in the Carriage - PCB on the backside of the carriage - New fanduct design which combines the powerful cooling from the MK3 with an easier assembling process and a more effective blower position & inflow - BLTouch usage possible (probe offset: X=+29, Y=-15) - Improvement for easier printing experience - no more support - Linear Ball Bearings (LM8LUU) or slide bearings (IGUS) possible - Either hex nuts or threaded brass inserts can be used --- Instructions on the stl-files, print settings & assembling process can be found in the project folders as a pdf file which is name '00_Instructions(...).pdf'. The assembly instructions are summarized in an instructional video which can be found here: https://www.youtube.com/watch?v=LadxXGYkU20 --- <b>Print/Slicing settings are given in the PDF-instruction files!</b> --- The project folder "MK4_Project_Repo.zip" contains the following sub-folders for the project organization: - 01_MK4_Hex_Nuts.zip `(In this variant all bolts are fixed with hex nuts)` - 01_Standard - 02_BLTouch - 02_MK4_Threaded_Brass_Inserts.zip `(In this variant most bolts are fixed with brass inserts)` - 01_Standard - 02_BLTouch - 03_Various_Parts.zip - xx_MK3_Carriage_repository.zip <i>Note</i>: 03_Various_Parts.zip contains additional parts which are optional to be used, for example a slightly wider belt clip or a rear bracket for dragchain usage. This folder will be updated from time to time with new files. --- If you want to use a drag chain you just must print the ´vp02_Dragchain_Rear_Bracket.stl´ instead of the regular rear bracket, additionally you have to print ´vp03_Dragchain_Extruder_Mount.stl´ which is mounted at the extruder. To mount the drag chain you will need 4x M3x10 bolts + nuts --- <b>If you mounted all parts on the printer take care before first homing! You may have to adjust the two z-screws on the linear carriage of z-axis so the nozzle doesn't crash on the heated bed, because it comes slightly lower with this carriage</b> The layout of the small hotend PCB is: - HOTEND = Heating Catridge - FAN2 = Coldend/Heatbreak Axialfan - FAN0 = Partcooling (Radial-)Fan - T0 = T0-Sensor (Thermistor) <b>Do not unplug a fan when the printer is turned on or do not turn the printer on when a fan is not plugged in you may risk damage to a transistor on the mother PCB!</b> --- <i>If you got any Problems, Improvements or Ideas feel free to leave them in the comments.</i> --- Changelog: - <b>04.05.2020</b>: Publication of threaded brass insert parts & parts for drag chain usage, update of instructional pdfs. - 07.05.2020: - Reduction of the tolerance oversize of the hexagonal recesses & hotend groove mount (user feedback) - Addition of the bore hole for fixing the hotend like with the MK3 Carriage in the Carrier Plate (Only if necessary to prevent rotation with an M3x10 screw) (user feedback) - Adaptation of the fanduct support for better removability of the supports (user feedback)
