Brother’s U.S. support answer gives a twin-needle threading path for a named group of LS, LX, and VX machines. It says twin-needle use is optional on some of the listed models, so first check that the manual for your exact machine permits the attachment and selected stitch. The answer does not state a twin-needle spacing; it cannot establish clearance for every foot, plate, or model.
The listed models are LS-1217, LS-1520, LS-1717, LS-2000, LS-2020, LS-2125/2125i/2129, LS2250PRW, LS2300PRW, LS2350, LS2400, LS-30, LX2375, LX3014, LX-3125/3125E, and VX3240. Confirm the full model name before using this procedure. UK and Canadian owners should use their local machine manual and regional support information.
Follow the listed thread path#
Brother says the two upper threads should have the same weight; they may be the same or different colors. Add the extra spool pin and thread each needle separately. The right needle follows the single-needle route. For the left needle, skip the thread guide immediately above the needle that the right-needle path uses.
On listed machines with a pattern-selection dial, the answer specifies straight stitches 6–10 or zigzag 2. It also calls for a zigzag foot, a width below 3 when a stitch-width knob is present, and middle needle position when that selector is available. These controls are conditional on the features of the listed model and remain subject to its manual.
Before sewing, verify the selected stitch and foot in the exact manual and turn the handwheel slowly to check that the needle clears the foot and plate. Test on scrap first. If the needle contacts anything, stop and correct the setup; do not use the motor to test clearance. See the general twin-needle guide for the broader setup checks.
