Barudan BEVT Series Embroidery Machine: Common Problems & Fixes

1. Frequent Thread Breakage high likelihood

How to tell

The machine stops frequently with a 'thread break' error, or you observe the thread snapping during embroidery. This can happen with upper thread or bobbin thread.

Fix

1. Inspect the entire thread path (from spool to needle) for any burrs, rough spots, or obstructions. Clean or smooth as necessary.
2. Check the needle for bends, burrs, or dullness. Replace the needle if any damage is found. Ensure the needle is inserted correctly and fully seated.
3. Verify upper thread tension. It should be firm enough to pull the thread smoothly but not so tight that it snaps. Adjust the tension knobs incrementally.
4. Check bobbin tension. The bobbin case should drop slowly when held by the thread. Adjust the bobbin case screw if needed.
5. Ensure the thread is appropriate for the fabric and needle size being used.
6. Clean the rotary hook area of any lint or debris. Check for burrs on the hook point.
7. Confirm the needle bar is not loose or misaligned. A loose Barudan HT230290 Needle Bar Driver Fixing Base Block can cause erratic needle movement leading to breaks.

A worn or damaged Barudan HT230290 Needle Bar Driver Fixing Base Block can contribute to needle bar instability and thread breaks.

2. Skipped Stitches or Uneven Stitch Quality high likelihood

How to tell

Embroidery appears incomplete with gaps in the stitching, or stitches are inconsistent in length or tension, leading to a messy appearance.

Fix

1. Replace the needle with a new, correct size and type for your fabric and thread. Ensure it's inserted with the scarf facing the rotary hook.
2. Check upper and bobbin thread tension. Adjust as needed to achieve balanced stitches.
3. Inspect the rotary hook for damage or lint accumulation. Clean thoroughly and ensure it's properly lubricated.
4. Verify the presser foot height and pressure are correctly set for the fabric thickness.
5. Ensure the fabric is properly hooped, taut, and stable. Loose hooping is a common cause of poor stitch quality.
6. Check the timing between the needle and the rotary hook. Incorrect timing will cause skipped stitches. Refer to your machine's manual for timing adjustments (often found in sections like '04A-1 Needle bar A(Z12)' and '08 Drive').

Parts involved: Needles & needle bars → Thread path & tension → Rotary hooks & bobbin cases → Presser feet & sewing parts → Hoops & frames → Head & mechanical parts →

3. Needle Breaking Frequently medium likelihood

How to tell

Needles snap or bend repeatedly during embroidery, often accompanied by a loud 'crack' sound.

Fix

1. Ensure you are using the correct needle size and type for your fabric and thread combination. Thicker fabrics or dense designs require stronger needles.
2. Check that the needle is inserted correctly and fully seated in the needle bar. A loose needle can break easily.
3. Verify that the fabric is properly hooped and taut. Loose hooping allows the fabric to move excessively, causing needle deflection.
4. Inspect the needle plate hole for burrs or damage. A damaged needle plate can snag the needle.
5. Check the rotary hook for damage or misalignment. If the hook point is hitting the needle, it will cause breaks. This often indicates a timing issue.
6. Examine the needle bar for any looseness or excessive play. A loose Barudan HT230290 Needle Bar Driver Fixing Base Block can lead to needle misalignment and breakage.

A faulty Barudan HT230290 Needle Bar Driver Fixing Base Block can cause the needle bar to wobble, leading to needle breaks.

Parts involved: Needles & needle bars → Hoops & frames → Rotary hooks & bobbin cases → Head & mechanical parts → Screws, springs & small parts →

4. Machine Freezes, Slows Down, or Won't Load Designs medium likelihood

How to tell

The machine's control panel becomes unresponsive, embroidery speed decreases significantly, or designs fail to load from the floppy drive/USB.

Fix

1. Perform a hard reset by turning the machine off, waiting 30 seconds, and turning it back on.
2. If using a floppy disk, try a different disk or clean the floppy drive head. Floppy drives are prone to failure.
3. If using a USB floppy emulator, ensure the USB stick is formatted correctly (FAT32) and contains valid design files. Try a different USB stick.
4. Check for any loose cables or connections, especially those related to the control panel or data transfer (refer to '11A Control A' and '11B Control B' sections of the parts book).
5. Consider replacing an aging floppy drive with a modern SFRM72-FU USB Floppy Emulator for improved reliability and compatibility with USB drives.
6. If the machine is generally sluggish or freezing, there might be an issue with the main control board or motor drivers. Consult a technician for advanced diagnostics.

The SFRM72-FU USB Floppy Emulator is a common upgrade to resolve issues with old floppy drives and improve design loading reliability.

5. Bird's Nesting (Thread Tangles Under Fabric) medium likelihood

How to tell

A large, tangled mess of thread forms on the underside of the embroidery, often causing the machine to stop.

Fix

1. Check the upper thread path for any obstructions or incorrect threading. Ensure the thread is seated properly in all tension discs and guides.
2. Verify that the upper thread tension is not too loose. If the upper thread is too loose, the bobbin thread will pull it to the underside.
3. Clean the bobbin case and rotary hook area thoroughly. Lint and debris can interfere with bobbin thread movement.
4. Ensure the bobbin is wound evenly and inserted correctly into the bobbin case. Use good quality bobbins.
5. Check the needle for damage or incorrect insertion. A damaged needle can disrupt stitch formation.
6. Confirm the presser foot is set correctly and applying adequate pressure to hold the fabric down during stitching.

Parts involved: Thread path & tension → Rotary hooks & bobbin cases → Needles & needle bars → Presser feet & sewing parts → Lubrication & maintenance →

6. Color Change Malfunctions low likelihood

How to tell

The machine fails to change colors, changes to the wrong color, or makes grinding noises during a color change sequence.

Fix

1. Check for any physical obstructions in the color change mechanism (refer to '07 Color change' section of the parts book). Remove any tangled thread or debris.
2. Ensure the needle bars are moving freely and not binding. Lubricate moving parts as per your maintenance schedule.
3. Inspect the color change sensor (if applicable) for cleanliness and proper alignment.
4. Check the motor responsible for color change. Listen for unusual noises or signs of strain. A failing motor or driver, such as an IHSS57-36-10-RC/EC Nema23 Integrated Stepper Motor Driver, could be the cause if the color change motor is a stepper.
5. Verify electrical connections to the color change motor and sensors are secure.

If the color change mechanism uses a stepper motor, a replacement IHSS57-36-10-RC/EC Nema23 Integrated Stepper Motor Driver might be needed if the existing driver fails.
