Embroidery machine — Brother PR-650

Six-needle embroidery machine. Moves a hooped workpiece under the needle following a prepared stitch file, changing between six thread colours and trimming automatically.

Brother PR-650

Hoops

Field size (width × height), with SVG templates for Inkscape:

Use the smallest hoop that fits, and leave clearance from the edge. One hoop has been repaired — check for cracks and secure attachment.

Materials and backing

• Fabric up to 1 mm thick (p. 34). Dense designs and overlap can break needles.

• Always use a suitable stabiliser/backing (pp. 90, 221–223). Backing cheat sheet above the hoops.

• Iron-on glue sheets for patches are also there — that's not embroidery backing.

• Hoop tight without wrinkles or stretching. Keep the rest of the garment clear of the arm and carriage.

Supplies

Drawers under the machine: manuals and software, bobbins and specialty thread, embroidery thread, backing. Spare needles below the machine with the manuals.

Manuals and software	Bobbins and specialty thread	Thread, drawer 1
Thread, drawer 2	Backing, drawer 1	Backing, drawer 2

Safety

• Hands, tools and loose fabric clear of needles, needle-bar case and carriage — they move during startup, colour changes and tracing too.

• Red Start/Stop = locked; flashing green = ready to start. Locked ≠ powered off.

• Switch off for needle changes and bobbins; unplug for cleaning.

• Stop for thread breaks, jams, needle strikes or shifted fabric. Never push the frame or needle case by hand.

Preparing the design

Hatch Embroidery (main workflow):

1. Machine & Hoop Options: pick the machine and hoop, show the hoop.

2. Digitise or edit: stitch types, density, underlay, colours, order. A picture isn't an embroidery file until digitised.

3. View → Stitch Player: check jumps, overlaps and colour order.

4. Save the .EMB (editable).

5. Output Design → Export Design → Brother PES. Hatch 4 exports in the background and needs internet — wait for the Exports panel to finish.

6. Copy the PES to a USB stick.

Ink/Stitch (alternative): Inkscape → Extensions → Ink/Stitch → Params / Simulator. Export with File → Save a Copy → Ink/Stitch Brother PES. Keep the SVG. Docs

Older Ink/Stitch guide

Limits: PES/PHC/DST only (no PEC/PMV). DST has no thread colours — assign them on the machine. Max ~500,000 stitches / 125 colour changes.

Needles, bobbin and thread

• Needles: Organ HAX 130 EBBR #11 (75/11), or Schmetz 130/705 H-E. Power off, Allen key and needle tool, flat side back, fully up (pp. 33, 86–87).

• Bobbins: L-type prewound (COATS/TRU-SEW) or Brother metal 100376-053. No built-in winder; no domestic bobbins.

• Loading the bobbin (pp. 36–37): power off, open the hook cover, remove the case. Thread unwinds clockwise seen from the open side; through the slit and under the spring, ~50 mm tail. Push in until it clicks. The machine can't tell how much bobbin is left — check before each job.

• Upper threads (pp. 56–58): raise the thread mast, open the spool stand. Bars are numbered 1 (right) to 6 (left). Each route: guides → one clockwise turn round the tension disc → middle guides → take-up lever right to left → lower guides. Routes differ per bar — follow the diagram. 40-weight rayon/polyester.

• Auto-threader (pp. 59–62), sewing locked:

  1. Select the bar, press the auto-threading button.

  2. Pull ~150 mm, pass it under the fork from the right and onto the hook.

  3. Under the foot guide, into its notch, into the cutter groove, cut.

  4. Press the button again. Never turn the handwheel with the hook in the needle.

How to use

1. Prepare the file (above). Test new designs on scrap.

2. Power off: check bobbin, oil the hook (daily, see Maintenance).

3. Load: USB stick in the top port, USB icon, pick the design, Set. Wait for loading to finish.

4. Hoop and attach: fabric + backing, holder width to the right mark. Frame level, inner frame on top, both sides clicked in. Start/Stop must be red.

5. Position and trace: align, then run the area check and watch for collisions (pp. 49–52, 96–99).

6. Colours: match each colour block to a needle bar. DST colours on screen are defaults.

7. Speed: ≤ 700 (flat) / ≤ 600 (caps); slower for new work.

8. Start: unlock key, then flashing-green Start/Stop within 10 s. Watch the first stitches and colour changes.

9. Finish: it trims and stops. Remove the frame, inspect both sides, unhoop, trim backing. Switch off, tidy.

Good to know

• Pause: Start/Stop (doesn't trim). Manual trim: stop, clear the area, unlock, press the thread-trim button (p. 66). Trim before switching off a paused job.

• Thread break / empty bobbin: fix it, then use stitch-back to overlap (pp. 105–111). After power loss, check the position before resuming.

• Long jobs: mark the hoop centre on the fabric (removable marks) in case the fabric slips.

• USB: directly in the port, no hub. "USB not loaded": try another stick or FAT32. Compatible sticks

• Tension: upper thread should show on the back. Test pattern p. 217. Check bobbin tension first (pp. 112–114) — don't turn every knob.

• Caps: cap frame, driver and jig — get mounting demonstrated (p. 225+, video). Sweatband out of the way, ≤ 600 spm. Check orientation. Put the normal holder back afterwards.

Troubleshooting

Maintenance

Sewing machine oil only, tiny drops — excess stains the embroidery.

• Hook race: 1 drop daily before use. Power off, remove the bobbin case, turn the wheel counter-clockwise (towards the screen) to expose the oil point (p. 250).

• Needle-bar felts: 1 drop per bar every 40–50 h (p. 251) — get it demonstrated; log it.

• Each bobbin change: clean lint under the case spring with paper — don't bend the spring (p. 247).

• Regularly: unplug, brush hook, needle plate, cutter and thread paths (pp. 245–249).

• Preventive maintenance message → arrange service; clearing it isn't maintenance.

• Threader, cutter, carriage, timing, electronics: Brother service.
