Step 1: Disassembly

• Disconnect & Remove All Wires Connecting to the Base of Your CNC
• Unscrew the Gantry Assembly from Either Side of the CNC's Base
• Take Apart Your Frame

Step 2: CNC Base Assembly

• Attach the Extended Side Extrusions & Linear Rails to the Back Panel
• Install Extended Lead Screw into CNC Bed Through Spring & Copper Nut
• Install the Bed with Threaded Lead Screw Into the Liner Rails Already Attached to Back Panel
• Secure the Lead Screw to the Y-Axis Stepper Motor through the Coupler
• Install the Front Panel & Square Frame

Step 3: Final Assembly

The process of mating the base frame with the gantry assembly mirrors the same process as when you assembled your CNC for the first time, the only major difference is that rather than having the gantry spaced 46.5mm from the rear of the frame, you are now going to want it to move more forward in order to take advantage of the expanded Y-Axis.

Rather than give you a specific number, it is strongly suggested that you move the gantry as far forward as your wiring will allow. This is usually around 60-80mm depending on whether you have limit switches.
