forkLIFT MK1 CoreXY 3D Printer

Facebook discussion group! https://www.facebook.com/groups/275444666421050/ This project was created using Token47's design from Thingiverse. I would love it if Thingiverse allowed multiple owners of a thing to collaborate. The main principles guiding the design of this printer are: * Be a platform for multi-tool development * Easy to print - no supports needed! No aggressive overhangs or bridges! * Components designed as best as possible to avoid fatigue and weakness due to layer adhesion. * The parts should be resilient to common printing errors like too smashed first layers, etc. If not, please let me know! * All motors are outside the printer chamber! This renders a free access from the front and no issues with chamber heating the motors. * Belt tension at motor mounts. Easy to adjust and not prone to loose adjustment due to vibration. * The X carriage is very versatile! You can put your tool on any side, use it upside down, and one of the main features is that it has enough space for a small step motor for tool changing or other uses you would like. This space can be used for hot swap plugs, servos, sensors... whatever! * Maintainability! All axis, bearings, etc. are removable without touching the belts! All screws are accessible. * Easy to close the printer as components have a good clearance from the outer plane of the frame. Even with 3030R extrusions! * Simple Z alignment: integrated parts! * Good looking! (This is open to debate.) The original concept was to have the full CoreXY gantry moving along Z, with a mechanism of counterweight to compensate the weight. However, for now, I would like to use all the hardware I have from my Hypercube Evolution. The X carriage is very versatile! You can put your tool on any side, use it upside down, and one of the main features is that it has enough space for a small step motor for tool changing or other uses you would like. This space can be used for hot swap plugs, servos, sensors... whatever! Facebook discussion group! https://www.facebook.com/groups/275444666421050/ The size limits for this design - without modifications - are: * Minimal heatbed screw holes distance: 209mm * Maximum heatbed screw holes distance: 330mm The bed can be up to 15mm bigger than those lengths on the X (i.e. 335mm for a 320mm holes distance). For the Z, you need to measure the distance between your floor and ceiling and subtract something like 300mm... just kidding! I am not sure how long the Z can be before it becomes wobbly. CHECK FOR UPDATES BELOW! The coreXY part is already tested and working nicely! ***Z still a work in progress***. Working with more instructions for every assembled part. Working on final BOM with all nuts and screws. Working on spreadsheet to calculate sizing, etc. Please be kind, this is my >first< 3D printer!
