Scalar - Upgrade Z Axis trapezoïdal screw

thingiverse

Description This upgrade is designed to improve the performance of Scalar XL 3D printers by replacing standard M8 leadscrews with Tr8x1.5 trapezoidal leadscrews on the Z Axis. The conversion process requires moving the leadscrew a little bit to accommodate a special nut, which is often necessary for trapezoidal leadcrews. Updates: July 28, 2016 - Added Nut holder for T8 nuts July 15, 2016 - Upgraded both top and bottom holders July 15, 2016 - Corrected motor holder for 8mm smooth rods, which was too short at 435mm To install this upgrade, you will need to print the following parts: Bottom Z axis motor holders Top Z axis smooth rod holders For Scalar XL: X axis motor holder (10mm) X axis idler holder (10mm) For Scalar M: X axis motor holder (8mm) X axis idler holder (8mm) Accessories: Nut adaptor for M8 or TR08X1.5 Hex Nut: http://www.thingiverse.com/thing:1379340 Special Notes: Top_Z_Holder 8mm.stl is reversible, making it suitable for both the right and left sides of the printer. Special Gcode: We have uploaded two Gcodes to help with the installation process: ConfigTR08x1.5.gcode, which allows you to reconfigure your printer's firmware settings with the correct Zstep/mm (2133.33 compatible with TR08x1.5) ConfigM8.gcode, which enables setting back the Z step/mm (2550) for M8 threaded rods Where to find TR08x1.5 Nuts: Igus polymer nut: http://3dmodularsystems.com/en/linear-motion/123-hex-nut-for-trapezoidal-leadscrew-tr08x15.html Steel TR8x1.5 nuts: http://3dmodularsystems.com/en/linear-motion/117-hex-nut-for-trapezoidal-leadscrew-tr08x15.html We appreciate your support and invite you to share your experience with others. 3D Modular Systems Evolutive 3D Printers If you enjoy our content and would like to contribute, please consider a donation: https://www.paypal.me/3DMS http://www.3dmodularsystems.com Twitter: https://twitter.com/3dmodularsystem Youtube: http://www.youtube.com/c/3DModularSystems3DPrinters
