X5SA to CoreXY Linear Bearing (RatRig,Vzbot,Voron,etc)

#History: I was looking to step up my Flsun Cube to a better motion system... and sometime project take strange sideways... Since I use this printer a lot... I wasn't willing to take him down for rebuild without a correct replacement during the downtime... ( ok i know i print too much lol)... So I got my hand on an affordable X5SA (not pro) version in late October... with the motivation of take it to the next level right out of the box... so my tronxy never exist as a genuine x5sa printer... This Project as been inspired by many other but mainly VZBot, Pooron, Ender 5 Pro Conversion, RatRig... #Project Description: ##Project Objective: The main goal was to get a better motion system than the OOTB system that came with the X5sa printer. Linear Rail was the logical path. In an effort to be able to enclose the printer everything has been design to enable an enclosure. ##Design Decision: For Sake of simplicity, I reuse the z axe contraption ( bed up-down motion system). We would need to add some spacers to enable side panel installation if enclosure is required, but doing that permit to avoid precise metal part modification and complex alignment job. I also add a bmg clone that was laying around... but could also work with the original extruder... For the y End Swith , I removed the hot glue from the original end stop pcb and bend the microswitch pin so it will be at 90 degree with the pcb ( see picture ) Head remain almost identical (no wiring change... I just replace the original cooling fan by a blower that fit the eva) I highly recommend you to switch to marlin or klipper for this mod ... and don't forget to offset correctly the bed sensor in the config ! #Project Requirements: ##Required 3d Printed Part (ABS+, ASA or ABS required for enclosed printer): Using the Vzbot gantry directly from vzbot github. (the 2 pulley corner, the 2 motor corner and the 2 x axis carriage) You must decide with or without tensioner for the
