CR-10S5 Convert to 10-12mm rods

thingiverse

Since the first renovation did not meet my expectations, I decided to upgrade using longer rods. The issue with the CR-10S5 lies in its very long shafts, up to 70cm, which tend to swing on their own when printing, especially at higher speeds. Printing worked well up to a speed of 30mm/s. However, the biggest problem was the Z-rods that swung excessively. I also encountered issues with the 12mm rods in the bed. The bed is quite heavy and needed additional support from below after installing new rails. Nevertheless, this upgrade proved largely useless for a large printer with low print speeds. After completing the rebuild, I was pleased to find that it prints exceptionally well and comparable to my Prusa MK3 printers. Here are the updated specs: * X-Rod: 10mm * Z-Rod: 12mm with LM12UU bearings * Y-Rod: 12mm with rail support I ordered these parts from eBay: https://www.ebay.com/itm/Linear-Guide-Supported-Rail-SBS12-700mm-long/273345235419?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 The motors may not need to be replaced, but I chose to swap them out anyway. Here are the motor specifications: * X Motor: 17HS8401-S * Y Motor: 17HS6401 * Z Motor: 2 x 17HS4401-S I replaced some parts and added completely new ones, including the Z-Top left and right for 12mm rods. Note that the X-MOTOR and X-IDLER are designed for 19mm spacing. I want to thank MIKEYMCC (Crearibo) for inspiring my renovation project! He provided me with the foundation I needed to get started, and I appreciate his contribution to the community.
