CoreXY 4040 Extrusion End Mount X/Y Motor Mount

thingiverse

I removed a top bar from my TronXY X5SA 500 Pro and flipped around my belts and printed these motor mounts that put the motor where it needs to be. This mod opens up access to the front of the printer to work with the build plate and also it mounts the X and Y steppers inboard so it reduces the printers external footprint without sacrificing any build volume. M3x9 screws were what I used for the stepper motors. Not for the faint of heart. To install: Remove the top front cross beam from the printer. Use the hardware that was holding the top beam in place to secure the motor mounts. 1 will need to be mirrored in the slicer before printing to create left and right sides. Once the mounts are installed and their bolts tightened the motors can be installed. The wires for the motors should lead off to the sides of the frame. There is one screw hole that is difficult to reach. This screw can be left out because of the way the stepper gets loaded or it can be installed with patience or my design intentionally has very thin wall thickness right at that hole and if you don't mind a hole in your mount you can drill a small hole at a carefully chosen height in relation to your specific allen key and installation and removal of that one screw becomes a whole lot easier.
