2. Understanding and Resolving Main Axis Stop Errors

When your Ricoma machine flashes a “Main Axis Stop” or “main axis not at 100 ricoma” error, it’s signaling that the main axis sensor isn’t detecting the idle 100-degree position. This can be caused by anything from a sensor drift to a thread jam or even a mechanical blockage. Let’s break down the essential troubleshooting steps to get you back in business.

2.1 Sensor Realignment to 100 Degrees: Step-by-Step Guide

The 100-degree position is the heartbeat of your Ricoma machine—its safe, idle state. If the sensor loses track of this position, embroidery grinds to a halt. Here’s how to realign and reset:

1. Power Off the Machine Always start with the machine powered down to avoid accidental movement.

2. Rotate the Degree Wheel Locate the degree wheel knob at the back of your machine. Turn it 2–3 full turns clockwise to clear any residual thread or debris.

3. Align the Red Arrow Stop turning when the red arrow on the degree wheel lines up precisely with the 100-degree mark.

4. Check for Resistance If the wheel turns smoothly, you’re on the right track. If you feel resistance, don’t force it—there may be a blockage (see Section 2.2).

5. Turn the Machine Back On Power up and let the machine initialize. Press the 100-degree icon on the control panel to confirm alignment.

6. Verify Error Resolution If the error clears, you’re good to go. If not, repeat the above steps or move on to mechanical checks.

Pro Tip: On models like the EM-1010 and MT-1501, make sure all take-up levers are at the same height for even tension before restarting.

2.2 Clearing Mechanical Obstructions in Rotary Hook Areas

If you feel resistance while turning the degree wheel, it’s time to investigate for physical blockages—often the silent culprits behind axis errors.

1. Remove the Sewing Arm Cover Loosen the screws on the bottom of the sewing arm to access the rotary hook and bobbin case.

2. Inspect for Thread Buildup or Stuck Needles Look for tangled thread, lint, or a needle jammed in the rotary hook area. Use tweezers or a small brush to gently clear debris.

3. Lubricate Moving Parts Apply a few drops of machine-specific oil to the rotary hook and surrounding components. Lack of lubrication can cause friction and trigger axis errors, especially after long periods of inactivity.

4. Reassemble and Test Replace the bobbin case and sewing arm cover. Rotate the degree wheel again to check for smooth movement. If you removed the rotary hook, you may need to re-time the machine (consult Ricoma’s timing guides).

Video Reference: Several YouTube tutorials demonstrate removing the cover, clearing jams, and resetting the axis—making the process less intimidating than it sounds.

3. Root Causes of 'Main Axis Not at 100' Errors

Understanding why these errors occur is half the battle, requiring Ricoma embroidery machine troubleshooting. Let’s shine a light on the usual suspects so you can prevent future breakdowns.

3.1 Needle/Hoop Collisions and Fabric Handling Solutions

What’s Happening: When the needle collides with the embroidery hoop or fabric bunches up during stitching, it can throw the main axis sensor out of alignment—leading to emergency stops and error messages.

Common Triggers:

• Using the wrong size or poorly positioned hoop
• Fabric slippage or bunching during embroidery
• Incorrect needle height settings

How to Prevent It: Proper hooping is your first line of defense. Traditional screw-based hoops often struggle to maintain even tension, especially with thick or slippery fabrics. This is where magnetic embroidery hoops, like those from Sewtalent, make a real difference. Their powerful magnetic clamping system automatically adapts to various fabric thicknesses, ensuring the fabric stays flat and stable throughout the embroidery process. This not only prevents needle/hoop collisions and sensor misalignment but also reduces visible hoop marks and fabric distortion.

Best Practices:

• Select a hoop size that matches your design and fabric
• Use a firm stabilizer to prevent shifting
• With magnetic hoops, simply position your fabric, let the magnets do their work, and enjoy consistent tension—no more wrestling with screws

3.2 Thread Jam Prevention Strategies

What’s Happening: Thread jams and buildup in the rotary hook area can create resistance, misalign the axis, and even block the sensor’s line of sight.

Prevention Tips:

• Bobbin Maintenance: Regularly clean the bobbin case and rotary hook area with a lint brush or compressed air.
• Tension Adjustments: Check and adjust thread tension to avoid both loose and overly tight threads, which can cause tangling or breakage.
• Quality Materials: Use high-quality thread and properly wound bobbins to reduce the risk of shredding or “bird’s nesting.”
• Routine Cleaning: After each project, inspect the rotary hook for lint or thread fragments.

By adopting these habits, you’ll keep your Ricoma running smoothly and minimize those dreaded “Main Axis Not at 100” interruptions.

Keeping your Ricoma embroidery machine humming is all about proactive care. Think of preventive maintenance as your insurance policy against those dreaded “Main Axis Stop” errors. Let’s break down the essentials—because a little oil and the right tools go a long way.

4.1 Rotary Hook Lubrication Schedule & Techniques

The rotary hook is the heart of your Ricoma. If it’s not gliding smoothly, friction builds up, leading to axis misalignment, thread jams, and—you guessed it—production-halting errors. Here’s how to keep it in top shape:

Twice-Daily Oiling: For machines running a full workday, Ricoma recommends applying 3–4 drops of Ricoma-approved machine oil to the rotary hook after removing any lint or thread debris. This simple ritual prevents friction-induced misalignment and extends your machine’s lifespan.

200,000-Rotation Maintenance: Every 200,000 z-shaft rotations (or as part of your scheduled maintenance), clean the rotary hook area with a brush or compressed air. Add a single drop of oil, then run a “sewout” on scrap fabric to absorb excess oil—protecting your garments from stains.

Weekly Alternating Lubrication:

- Needle Bar: Add oil through the small holes at the rear of the head.

- Rail Tracks: Lubricate the side rails for smooth needle movement.

Periodic Greasing: Every 3–5 months, apply white lithium grease to the black metal bar, wheels, and color change cam. This reduces wear and keeps your machine running like new.

Thread Buildup Prevention: Daily cleaning is non-negotiable. Remove lint and thread fragments from the rotary hook area after each use. Maintain a tidy workspace to minimize airborne debris—think of it as embroidery’s version of keeping your kitchen clean.

Safety First: Before any maintenance, power down your machine. Ensure all moving parts have stopped, and follow lockout/tagout (LOTO) protocols to prevent accidental startups.

The Magnetic Hoop Advantage: Here’s where magnetic embroidery hoops, like those from Sewtalent, shine. Their mighty hoops for Ricoma MT-1501 magnetic clamping system holds fabric securely, reducing lint and thread shedding during garment embroidery. Less debris means less frequent cleaning and a lower risk of axis errors.

By sticking to this maintenance rhythm, you’ll dramatically reduce downtime and keep those “Main Axis Not at 100” errors at bay. Your machine—and your sanity—will thank you.
