Cutter is skipping areas when cutting

If your JUKI HZL-DX7 sewing machine's automatic thread cutter is leaving behind a short piece of thread in the mechanism after each cut, there might be a few potential causes for this issue. Here are some steps you can take to troubleshoot and address the problem:

1. Thread Tension: Check the tension settings for both the upper and lower threads. Improper tension can cause thread to be left behind in the thread cutter mechanism. Make sure the tension is balanced and appropriate for the type of fabric you're sewing.
2. Thread Quality: Poor-quality or thick threads can sometimes get caught in the thread cutter mechanism. Ensure you're using good-quality threads that are suitable for your sewing project.
3. Thread Path and Thread Guides: Make sure the upper and lower threads are properly threaded through the machine's threading path and guides. Improper threading can lead to thread buildup in the cutter area.
4. Thread Cutter Mechanism Cleaning: The thread cutter mechanism might have accumulated lint, debris, or bits of thread over time. Gently clean the thread cutter area with a small brush, compressed air, or a vacuum cleaner to remove any buildup.
5. Blade Inspection: Check the blade of the thread cutter for any nicks, dullness, or damage. A damaged blade might not cut the thread cleanly, leaving behind remnants.
6. Thread Cutter Mechanism Lubrication: Some sewing machines have small moving parts in the thread cutter area that benefit from occasional lubrication. Consult your sewing machine's manual to see if lubrication is recommended and use a sewing machine-safe lubricant if needed.
7. Machine Maintenance: Regular maintenance of your sewing machine, including cleaning and oiling as recommended in the manual, can help prevent issues with the thread cutter mechanism.
8. Consult the Manual: Refer to your JUKI HZL-DX7 sewing machine's manual for specific instructions on troubleshooting and maintaining the automatic thread cutter.
9. Professional Service: If the issue persists after trying these steps, it might be best to seek the assistance of a professional sewing machine technician. They can diagnose and repair any mechanical issues with the thread cutter mechanism.

Remember that working with sewing machines involves mechanical parts and electrical components, so it's important to follow safety guidelines and, if needed, seek professional assistance to avoid causing further damage or harm.

Just follow the steps given at this link, and your cutter should begin to cut again. I just tried it and my cutter is back cutting. Cricut Craft Room Troubleshooting Cricut Help Center

Try cutting another piece and cleaning it out again. It's the sensor that is dirty not the cutter

You state you put too much oil in the cutter. then you state it uses straight gas. All the cutters I ever used had a mix of 2 cycle oil and gas. Usually when you place too much oil in the mixture it fouls the spark plug and could cause carbon build up. If the plug has oil on it it will never ignite. Do not put straight gas in the fuel to try to burn off the oil you will only make matters worse. Clean the plug, drain your fuel and start from scratch. If it still fails to start, you need to bing it in to a small engire repair shop. Good Luck!!

Hi, have you ever cleaned the unit out? If you have air pressure available, this is the easiest way to do it. Blow all the old dead grass, weeds ect out from the engine area of the Weed eater. If you don't have or have access to a compressor, take the unit to your local garage/service station and ask to use their air, or ask them to blow it out for you. This alone may cure the problem. However the proper mix is critical for proper performance also. If the mix is too lean the unit will over heat. Clean it out, and be sure of the mix ratio. You should be 'good to go'. Good Luck Vern

Like an other welding job - be sure the grounds are clean and secure. Ground as close to cut as practical and if trying to cut painted area - remove paint for good ground and to cut down on fumes from burning/melting paint. Disconnect battery as well so as not to bachfeed any voltage into your electrical system. IE ecm - computer

Pop of bottom cover and wrap new line by turning head or replace with different spool or blade cutter

There are a few things about plasma cutting safety that are different from general welding safety tips This short list of plasma cutter safety tips is geared toward light duty plasma cutting using compressed air not large industrial units that use gas mixtures and water cutting tables. Electric Shock Can Kill - Operating a plasma cutter completes an electric circuit between the torch and the workpiece. The workpiece and anything touching the workpiece are part of the electrical circuit. - Never touch the torch body, workpiece or the water in a water table when the plasma system is operating. Voltages & Currents - Plasma cutter output voltages are much greater than welding voltages, usually 100-200 volts. Precautionary Measures - Do not pick up the workpiece, including the waste cutoff, while you cut. Leave the workpiece in place on the workbench with the work cable attached during the cutting process. - During plasma cutting operations do not move the work clamp. Wear insulated gloves and boots, and keep your body and clothing dry. - Do not stand, sit or lie on or otherwise touch any wet surface when using the plasma cutter system. - Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground. If you must work in or near a damp area, use extreme caution. Work Cable - Ensure metal-to-metal contact between work cable and workpiece or work table. - Work cable clamp should make contact with clean metal free of rust, dirt, painted surfaces, etc. - Do not attach work cable to the piece that will fall away when the cut is complete Plasma cutter Arc Rays Plasma cutter arc rays produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Protective Clothing - Guantlet gloves, safety shoes and hat. - Flame-retardant clothing to cover all exposed areas. - Cuffless trousers to prevent entry of sparks and slag. - Remove combustibles, such as a butane lighter or matches, from your pockets before cutting. Noise Levels of Plasma Arc Cutting - Plasma arc cutting systems can generate noise levels in excess of 120 dB during high-amperage cutting operations. - Ear protection should be used when operating or working near plasma arc cutting operations. Toxic Fumes & Gases Plasma arc cutting can produce toxic fumes and gases that deplete oxygen and cause serious injury. - Keep the cutting area well ventilated or use an approved air-supplied respirator. - Do not cut in locations near degreasing, cleaning or spraying operations. The vapors from certain chlorinated solvents decompose to form phosgene gas when exposed to ultraviolet radiation. Pacemakers & Hearing Aids - Pacemaker and hearing aid operation can be affected by magnetic fields from high currents. Pacemaker and hearing aid wearers should consult a doctor before going near any plasma arc cutting and gouging operations Overall Plasma Safety - The plasma arc cutting process can be very safe. - By paying attention to safety standards and correctly setting up and operating the system, plasma arc cutting poses no more a threat than most welding processes.
