Keiran XY Carriage System

thingiverse

I'm making an Ultimaker Clone that uses minimal hardware, printing all parts except frame and electronics. Constant testing and printing are underway with mods on nearly every model, wasting over 300 feet of filament in the process. I'd appreciate support for my project as it's not intended for non-3D users but rather for those who want to quickly build a quality printer without hardware barriers, awaiting overseas shipping of bulk hardware. I've updated the design since its inception, so some files may be unfamiliar. To ease understanding, STL file names in the ZIP are carefully labeled with what they represent. (Current Status 4/2/16) I added a HotEnd Carriage with modified LM10UU holes. This does not include printed LM10UU bearings; it's recommended to use real ones for optimal performance. The X and Y carriages have been redesigned, now distinct from one another to accommodate the new hotend carriage. Two versions of each are available: one with the LM10UU printed into the carriage and one without, allowing users to choose between real or printed bearings. Frame brackets and bolts were also uploaded in a previous update. The next step is to build the Z Axis system, motor mounts (an easy task), and upload pulleys. Onward to the Borafill! (Update 4/2/16) X Carriage and Y Carriage files have been added, each with two versions: one with LM10UU printed into it and one without, allowing users to choose between real or printed bearings. An adopted Ultimaker HotEnd Carriage with modified LM10UU holes has also been uploaded. (Update 3/31) Frame brackets with fitted bolts and a bolt wrench have been added. (Update 3/29/16) The XY carriage has been replaced with thicker wall support for the X-Cross sections. -Added the "LM10UU Linear Bearing Test Print File" PRINT THIS FIRST! SEE BOTTOM INFO! This is a complete build from scratch of an X Y System, designed to run with 25mm extrusion rods for corner brackets and requires minimal hardware. The linear bearings are printed from LM10UU self-center bearings found in several places. Rods (I'm using 3/8 inch rods) are built for 10mm smooth rods but can also accommodate 3/8 inch rods. The hot end mount is built into the carriage and designed for the E3D V6. I'll add fan mounts later, allowing users to choose their preferred setup. If issues arise, I'll update accordingly. This design took a couple of days in Tinkercad, and I'd appreciate feedback and support. Please note that you won't print 10mm rods as they were added to Tinkercad for alignment purposes only. Additional Information: Please first print the LM10UU Test Size file. This is set at 10mm, and all printers have small deviations (50-100 Microns), which will affect carriage smoothness. I've added this test print file, and it takes about 10 minutes to complete. Print it on highest resolution at maximum fill for optimal quality. If you need to offset the XY Carriage set, change your print settings to 0.99 or 0.98% (.99 is -100 Microns, .98 is +200 Microns). I had to do this with my setup using 3/8 inch rods. Dowel rods for bearings are set for 4mm Inside Diameter Rods. Make proper modifications for your chosen bearings. Printable bearings will be added to match these rods, further reducing hardware requirements. The carriages are designed for common GT2 Timing Belt use. A finish build photo will be posted soon to show my setup in action. This build takes out 90% of the hardware factor, just like other CORE XY systems. Print Settings: Printer: M3D Rafts: Doesn't Matter Supports: Yes Resolution: Medium/High Infill: Medium/High Notes: I printed everything on mine in medium quality and fill with no issues. The linear bearings are a snug fit at first but running them up and down the rods for 20 seconds breaks them in for perfect size. Design Notes: Tinkercad
