TronXY X5S - upgraded parts for Gantry and Belt Idlers

thingiverse

For the TronXY X5S I have designed some upgrade parts to improve the gantry's performance and durability. The Acrylic parts used in the stock design tend to flex and break easily, so I've created custom components to address this issue. See a short video clip demonstrating these upgrades here: https://youtu.be/3yFbaJzWN30 The stock belt path is not parallel or perpendicular as needed, which led me to design custom Corner Idler Plates. These plates feature ridges and counter-sunk extrusion cur outs for added sturdiness. The four-wheeled Y carriages have an excessive number of wheels, with three being sufficient for a plane. During movement, I noticed that some wheels were not turning due to forces on the plates. The 3 Wheeler upgrade solves this problem and adds ridges and counter-sunk extrusion cur outs for increased durability. Parts included in this upgrade: Printed parts (printed at 0.28 layer height, 4 top/bottom/perimeters with 80% full Honeycomb Infill): * 2x X5S_Y-carriage_3w_ridged_spacers.stl ('3 Wheeler edition' with ridges and integrated wheel spacers) * 1x Corner_Idlers_Plate.stl (standard version for Front Left side) * 1x Corner_Idlers_Plate_mirrored.stl (mirrored in XY for Front Right side) * 8x M5_holder_608_bearing.stl (for idler use) * 8x 608_bearing_sleeve.stl (for idler use) Additional files available at SgaboLab's Thingiverse page: https://www.thingiverse.com/thing:2574935/#files These include: * 2x spacer A1-spessore-cuscinetto-cinghie-carrelli-8e4mm.stl (for high idlers on Y carriage) * 2x spacer C-spessore-torri-cuscinetto-20x8e4.stl (for high idlers on Corner Idler Plates, print at 1mm lowered in Z height - 7mm high) * 1x B2-staffa-cart-estrusore-V2.stl (for X Carriage belt riser) * 3x B1-spessore-ruote-ext-6mm.stl (for X Carriage Wheels) Hardware needed: * 8x 608zz bearing (if not using official idlers and opting for custom idlers) * 4x M5x50 screws * 3x M5x40 screws * 1x M5x35 screws (re-use from kit) * 2x M5x30 screws (re-use from kit) * 10x M5 washers medium size * 12x M5 washers small size (re-use from kit) * 4x M4x16 screws * 4x M4x9 screws (re-use from kit) * 8x M4 washers medium size * 12x M4 washers small size (re-use from kit) * 8x T-nuts (re-use from kit) Instructions and parts used: Y-Carriage: To assemble the mirrored right side corner idler plate, use free-side cutters to snip off part of the outside ridge where the end stop plate is mounted. See photo. Front Left corner idler plate: * High idler: M5x50 screwed into frame * Low idler: Use the M5x25 from the frame Front Right corner idler plate: * High idler: Use a M5x40 (M5x35 from stock wheel setup is too short) * Low idler: M5x50 screwed into frame Mount plates to extrusion using M4x16 with M4 medium washers and hammer nuts.
