This is a mod for the SimpleCore Redux that moves the linear rail to the front. It allows for better COM and full compatibility with Monolith based toolheads! The files are ready to print and I have included .F3D and .STEP for those who wish to modify, happy printing and enjoy! This mod is designed to use pins, M5 thread is not recommended for longevity, please use the 5mm pins from the BOM.

ONLY THE BOM 20T IDLERS ARE COMPATIBLE WITH THIS MOD, if you purchased 20T idlers with a flange larger than 15mm YOU WILL HIT THE X EXTRUSION. If you replace these with F695 bearings, you will skew the belt path and introduce futher VFA into your printer. You have been warned!

To install:

1. Mount the 2020 extrusion to the XY Joints
2. Allign the XY Joints to the Y axis linear rail carriages
3. Screw it down using M3X6 BHCS, SHCS will collide with the 2020.
4. Derack by loosening the 4 M5 screws that fix the extrusion to the xy joints and make sure that it is parallel at each side of the gantry front and back.
5. Secure the M5 screws and proceed to installing your bearings and pins
