Upgrades for Pending LongMill MK2 Orders


This product allows customers who are waiting on their LongMill MK2 12×30 or 30×30 machines ordered to extend their X-axis to have a working area of 48 inches. Your kit will be upgraded to include the 57″ rail, T12 lead screw, T12 coupler, T12 anti-backlash Delrin nuts, extension cables, bearings, gantries, and all of the other components you’ll need to set up the larger X-axis rail.

Please note that upgrading your order will delay your shipment to July 2022. 

You must have a pending LongMill MK2 pre-order to purchase this item. If you are looking for an extension kit for your existing machine, please visit the 48″ X-Axis LongMill Extension product page.


The order number is a 6 digit number used to identify your order.



Step 1) Identify your order number

Find your order number. You should have gotten an email confirmation about your order. Order numbers have 5 digits (eg. 36111). Please ensure that your order number is for your LongMill MK2 Pre-order.

Step 2) Place the order

Place this item in your cart, along with any other items you might want (end mills, accessories, add-ons). Please note that shipping will be charged. Because the 57″ X rail needs to shipped separately from the rest of the kit, the shipping fee for this item cannot be combined with your previous order.

Step 3) Wait for processing

We will process and combine the two orders. You will get a confirmation once the process is complete. Please note that it may take 3-5 business days to complete the processing.

Step 4) Wait for your order to ship

Once the parts are ready to ship for your machine and other parts you ordered, you’ll get an email to let you know that you have a shipment on the way. In the meantime, please feel free to read about news, monthly production updates, and product releases on our blog.
