I upgraded my Voron V2.4 with a CAN-toolboard. To fully replace the x and y drag chains, it is necessary to relocate the X and Y endstops. For X, there is a mount at the back of the toolhead carriage. For Y, it's common to move the endstop to the B-motor mount (right rear position).

There are several relocation mods. They require either to completely rebuild the B motor mount, or they cost buildspace in Y. 

This mod screws on the regular motor house. You need two longer screws M3x35 for the motors and 2x M2x10 self-tapping screws. There are no modifications to existing parts.

Update 25.12.23: Some M2x10 screws have a thicker head, so I added a version with 1mm extra space.

BOM: 

Microswitch, i.e. Omron D2F-5L ("L" is important, it's the springy latch style)

2x M2x10 self-tapping screws to fasten the microswitch

2x M3x35 screws to fasten the endstop bracket on the gantry

Printing instructions:

Standard Voron setup, 3-4 perimeters, about 25% infill

The parts are oriented in the best printing position

Use ABS or better, this is a Voron, they get warm :)

Assembly: 

• Solder wires to the endstop. Use the two outer pins, don't connect anything to the inner one. If you are unsure about this, check the V2.4/Trident manual, there are instructions for the wiring of the x and y endstop switches. No changes on that procedure.
• Use 2 M2x10 self-tapping screws to fasten the microswitch in the bracket.
• Turn out the two front screws for the stepper motor, use M3x35 to attach the bracket. The holes are actually slots for endstop adjustment. I get good results when the bracket is flush with the motor housing.
• Connect the wires to your MCU.
• Fasten the bumper to the gantry, use the holes and screws that you used for your cable bridge. The mount was designed for the stock screws.
