forkLIFT MK1 CoreXY 3D Printer

This is a project made with Token47 I would like that Thingiverse could allow multiple owners of a thing :D

The main principles guiding the design of this printer:

• 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.
• De parts should be resilient to common printing errors like too smashed first layers, etc. If not net me know!
• All motors outside the printer chamber! This render 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.
• Very versatile X carriage! Just swap the "Plates 42" to whatever you want, from your legacy printer head to lasers! Also designed with tool changing in mind.
• Maintainability! All axis, bearings, etc. removable without touching the belts! All screws 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 :D )

The original concept is to have the full CoreXY gantry moving along Z, with a mechanism of counterweight to compensate the weight.

But for now I would like to use all the hardware I have from my Hypercube Evolution :D

The X carriage is very versatile! You can put your too to any side, use it upside down, and one of the main features is that it have enough space for a small step motor for tool changing or other uses you would like. This space can be used fot hot swap plugs, servos, sensors... whatever :D

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 lenghs 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 substract something like 300mm - :D Just kidding. I am not sure how long the Z can be before it became 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 :D
