How to assemble the Extension Kit
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.

United KingdomEasy upgrade to double the size
The extension kit was very well packaged and all parts clearly identified, including the correct number of screws. Instructions for assembly were straightforward and accurate, and I now have a CNC twice the size!

Mark E. United StatesGreat Customer Service (again)
As I assembled my extension kit, I discovered that the two Y axis linear rails differed in length by 1mm. While I could have tightened the screws to make it fit, doing so noticeable bowed the Bakelite end pieces. I decided the shim the shorter rail with a couple M4 washers (one on each end). That seems to work fine. Just to be safe, I contacted Sainsmart customer support to make sure that was acceptable. The next morning there was a shipment notice that Sainsmart had shipped out replacements.
