A must if you have a water-cooled spindle!

These brackets support a large drag chain on the Onefinity CNC machines. 

How much can fit in a 18x50mm drag chain?  A lot. Heres what fits:

  • The stock Onefinity Elite cables
  • PwnCNC spindle power cable
  • Two 10mm coolant lines
  • Three 6mm PwnCNC ATC air lines
  • PwnCNC ATC motor sense cable
  • J-Tech laser cable
  • 4mm air-assist
  • 8mm air blast line
  • Two 6mm dust boot air lines
  • One dust boot control cable

That almost fills it up.  Perfect for the great majority if Elite owner.


Make sure you select the proper options so that you'll receive the correct brackets for your machine and drag chain.

18x50mm Drag Chain Requires can operate with just the black aluminum drag chain trough that comes stock on the machine.  However, we recommend adding one 1/8" thick, 1" aluminum angle to each axis for better support of the drag chain.   If you prefer you can use two matching lengths of aluminum angle per axis.

The aluminum angle will need to be about 6" longer than your axis.  So, that's 54" for a 48" axis and 38" for a 32" axis.


25x90mm Drag Chain Requires:

If you're mounting these to an X50 without stock drag chains, you'll also need:

  • Two 70mm M5 cap screws
  • Two 80mm M5 cap screws
  • Four 85mm M5 cap screws


We print these in  PETG, with 6 wall loops and heavy infill, giving them superior material strength.  More than sufficient to support a heavy drag chain.   

The aluminum angle brackets mount in the same way as the stock brackets.  They interface perfectly with the stepper motor cable connectors, just like the stock brackets.   The drag chain connectors use the original hole on the gantry block and the second hole, which the stock one is not large enough to reach.

If you use a rear-mount dust boot, you may also need an offset adapter so that your dust hose doesn't rub on the drag chain trough.  You can order it as an option or separately, here (   Or, if you need a rear mount dust boot, the Big Suck works great with aftermarket drag chains.
