Description

Identifying if you have a LongMill MK1 or LongMill MK2

If your machine uses angle aluminum rails, you have a LongMill MK1. This encompasses virtually all machines that were shipped between Oct 2019 till Feb 2022. Your order receipt will list the machine as “LongMill Benchtop CNC”.

If your machine uses custom extruded rails, you have a LongMill MK2. This encompasses machines shipped after March 2022. Your order receipt will list the machine as “LongMill Benchtop CNC MK2”.

The 48″ X-Axis LongMill Extension Kit allows LongMill MK1 and LongMill MK2 users to increase the working area of their machines to 48 inches in the X-axis direction. This allows users to fit full 4ft wide sheets into their machines for cutting.

The Extension Kit for LongMill MK2 (also referred to as the base extension kit) comes with:

  • 1pcs 57″ X-Axis Rail
  • 1pcs NEMA 23 Motor Cable Extension
  • 1pcs extension cable for router (compatible with Makita RT0701)
  • 2pcs Y-Axis Gantry for 6001ZZ Flange Bearing
  • 1pcs T12 Lead Screw
  • 1pcs T12 Delrin Anti-Backlash Nut
  • 1pcs T12 ACME Locking Nut
  • 2pcs 6001ZZ Flange Bearing
  • 1pcs 15×20 drag chain extension
  • Assorted Hardware for Mounting and Assembly

The Extension Kit for LongMill MK1 and Adapting Brackets comes with everything in the base extension kit plus brackets to adapt your LongMill MK1 XZ gantry and drag chain to the larger T12 hardware used.

The Extension Kit for LongMill MK1 and MK2 XZ Gantry Assembly comes with everything in the base extension kit plus a full assembly of the X and Z gantry used on the MK2 machine.

Base Extension Kit

The Base Extension Kit comes with:

  • 1pcs 57″ X-Axis Rail
  • 1pcs NEMA 23 Motor Cable Extension
  • 1pcs extension cable for router (compatible with Makita RT0701)
  • 2pcs Y-Axis Gantry for 6001ZZ Flange Bearing
  • 1pcs T12 Lead Screw
  • 1pcs T12 Delrin Anti-Backlash Nut
  • 1pcs T12 ACME Locking Nut
  • 2pcs 6001ZZ Flange Bearing
  • 1pcs 15×20 Drag Chain Extension
  • Assorted Wire Management Components
  • Assorted Hardware for Mounting and Assembly

MK1 to MK2 Adapting Brackets

Due to the different drag chain routing methods and changes to the hole mounting on the T12 Delrin Anti-Backlash Nut, the MK1 to MK2 Adapting brackets are needed to use your original MK1 XZ gantry on the MK2 rails. Each MK1 to MK2 Adapting Brackets kit comes with:

  • Mounting bracket for T12 Anti-Backlash Nut
  • Mounting bracket for the X-Axis Drag chain
  • Assorted Hardware for Mounting and Assembly

MK2 XZ Gantry

Optionally MK1 machine users can replace their full XZ Gantry to the latest version of the MK2 XZ Gantry. Since the MK2 XZ Gantry comes with the mounting holes for the T12 Delrin Anti-Backlash Nut and also shares the same drag chain mounting pattern to the X rail, the MK1 to MK2 Adapting Brackets are not needed for assembly.

*IMPORTANT: Because the MK2 X Gantry has different mounting holes for the dust shoe, the original LongMill Magnetic Dust Shoe brack is not compatible. The new, updated MK2 dust shoe that is compatible with the MK2 X Gantry can be found here: https://sienci.com/product/longmill-magnetic-dust-shoe-mk2/ 

Adding the Extension Kit to the LongMill MK1

You will need the Base Extension Kit, as well as either the MK1 to MK2 adapting brackets OR the new MK2 XZ Gantry.

If you choose the MK1 to MK2 adapting brackets, you can use your original MK1 gantry on the X-axis rail.
