2. Critical Error Code Fixes: Error 20 & Error 06
2.1 Solving Main Driver Ready Error 20
When your Inbro machine flashes "Error 20 (Main Driver Ready Error)," it's signaling trouble with the main motor or its control systems. This error can feel like a dead end, but with a methodical approach, you can often get back on track quickly.
What Causes Error 20?- Faulty main motor or control board
- Power supply issues (unstable voltage, blown fuses)
- Contaminated or misaligned 100° position sensor
- Loose or faulty wiring connections
- Check the Fuses: Inspect F1 (250V/3A), F2 (250V/4A), and the noise filter fuse (250V/6.3A). Replace any that are blown. According to the Inbro IB-RSC1501 manual, these are located on the joint board behind the arm side cover.
- Verify Power Supply: Ensure your input voltage matches the machine's requirements (typically 110V, 3A, 50/60Hz). Unstable or incorrect power can trigger Error 20.
- Inspect the Main Motor Belt: Open the machine's side panel and check if the main motor belt is intact and properly tensioned. A broken or loose belt can halt the main shaft.
- Clean the 100° Position Sensor: Oil or debris can block the sensor, preventing the machine from recognizing the correct stop position. Remove the sensor and gently clean it with a Q-tip-just as demonstrated in the "EC20 Main Motor Error" YouTube tutorial. Be careful not to oversaturate the area with oil, as excess can seep onto the sensor and magnets.
- Check Wiring and Connections: Inspect all cables connecting the main motor, control board, and dry box. Unplug, check for secure contacts, and replug to ensure tight connections. Loose screws or connectors can interrupt data transfer and trigger the error.
- Replace Faulty Components: If the above steps don't resolve the issue, the main motor, control board, or sensor may need replacement. Forum users have reported success after swapping out the control unit, though sometimes persistent issues require professional support.
Pro Tip: If you can manually rotate the main shaft without resistance, the motor should be able to drive it. If it's jammed, check for obstructions under the needle plate or within the rotary hook.
Summary Table: Troubleshooting Error 20| Component | Action |
|---|---|
| Fuses | Check/replace F1, F2, noise filter fuses |
| Power Supply | Verify voltage and amperage |
| Main Motor Belt | Inspect for wear, adjust tension |

When in Doubt: Consult your Inbro maintenance manual for model-specific guidance, and don't hesitate to call in a technician for persistent or complex electrical faults.
2.2 Resolving Motor Lock-Up Error 06
"Error 06 (Motor Lock-Up)" is your Inbro's way of saying, "Something's stuck!" This error usually points to a mechanical jam-often a tangle of thread, a bent needle, or debris under the needle plate.
Common Culprits:- Tangled thread or fabric blocking the needle area
- Bent or damaged needle colliding with the plate
- Debris or lint under the needle plate or in the rotary hook
- Needle plate not securely attached
- Clear Obstructions: Remove the needle plate and rotary hook cover. Look for and remove any tangled thread, fabric, or debris. Sometimes, thread can wrap around the back of the rotary hook, causing a jam.
- Check and Replace the Needle: Inspect the needle for bends or damage. Replace it if necessary to prevent further collisions.
- Secure the Needle Plate: Make sure the plate is firmly attached and aligned. A loose plate can block the needle's path.
- Restart the Machine: Power off, wait a few moments, and restart. This resets the motor and may clear the error if the obstruction is gone.
Reference from Manuals: The Inbro IB-RSC1501 manual emphasizes checking the main motor belt and ensuring the emergency switch is off before troubleshooting. Always follow safety protocols and disconnect power before opening covers.
YouTube Insights: Videos on similar error codes (like the EC20 Main Motor Error) demonstrate the importance of regular oiling-just a drop or two weekly-to keep bushings lubricated and prevent jams from heat expansion.
Quick Checklist for Error 06:- Remove all thread/fabric from the needle area
- Replace bent or damaged needles
- Clean under the needle plate and rotary hook
- Ensure the needle plate is secure
- Power cycle the machine
If Error 06 Persists: Consult your service manual for further mechanical checks, or contact an authorized Inbro technician for help.
3. Technical Documentation & Component Specifications
3.1 Fuse Replacement Guide (F1 250V/3A, F2 250V/4A)
When dealing with electrical issues or persistent error codes, fuse inspection is a crucial first step. Inbro machines typically use the following fuses:
- F1: 250V/3A
- F2: 250V/4A
- Noise Filter: 250V/6.3A
Finding and Replacing Fuses:
- Locate the Fuses: According to the Inbro IB-RSC1501 manual, fuses are found on the joint board behind the arm side cover. The noise filter fuse is located inside the noise filter unit.
- Check Fuse Continuity: Use a multimeter to test each fuse. If a fuse is blown (no continuity), replace it with one of the exact same rating.
- Verify Power Input: After replacing fuses, ensure your power supply matches the machine’s specifications (110V, 3A, 50/60Hz). Fluctuations or surges can cause fuses to blow repeatedly.
- Reassemble and Test: Once new fuses are installed, reassemble the covers and power on the machine. Monitor for recurring errors—if fuses blow again, further electrical inspection is needed.
Diagram Reference: Service manuals often include diagrams showing fuse locations and wiring paths. Always refer to your model’s official documentation for precise instructions.
3.2 Belt Tension Best Practices
A well-tensioned belt is the unsung hero of smooth embroidery. Too loose, and you’ll face skipped stitches or misalignment; too tight, and you risk premature wear or motor strain.
Preventive Maintenance Schedule:
- Weekly: Inspect the main motor belt for signs of wear, fraying, or slack. Adjust tension as outlined in your Inbro manual—usually by loosening the motor mount bolts, adjusting position, and retightening.
- Quarterly: Remove the belt and check for cracks or hardening. Replace if necessary.
How Magnetic Hoops Like MaggieFrame Help: Consistent fabric tension during hooping reduces the strain on your machine’s drive system. Magnetic embroidery hoops such as MaggieFrame keep fabric stable and evenly taut, minimizing the risk of slippage that can cause the motor belt to overcompensate and wear out faster.

If you've ever watched your Inbro embroidery machine veer off course mid-design, you're not alone. Design misalignment—where the stitched pattern suddenly jumps or skews—is a headache echoed across user forums and T-ShirtForums discussions. What's really going on, and how do you fix it for good?
Understanding Frame Limit Errors
Inbro machines are vigilant about their boundaries. When a design approaches or exceeds the preset frame limits, the machine throws up "Left/Right/Upper/Lower Limit Errors" and halts embroidery. Even before you start, if the design's start point is outside the operational area, you'll get a pre-start limit violation. These aren't just random quirks—they're built-in safeguards to prevent costly fabric or needle damage.
Community Insights: What Users Report
Forum users describe alignment issues that seem to strike at random—sometimes after dozens of perfect runs. Some have called in technicians, swapped circuit boards, or even upgraded software, but the problem can persist. Interestingly, one recurring theme is that memory overload (storing too many designs on the machine) may exacerbate misalignment, so keeping your design library lean can help.
Practical Solutions
- Adjust Frame Limits: Use your machine's settings to modify frame boundaries or, if needed, temporarily disable limit checks for tricky designs.
- Check Design Placement: Always ensure the design's start point is well within the frame's operational area before pressing "start."
- Clear Out Old Designs: Reduce the number of stored designs to prevent memory-related glitches.
The Power of Proper Hooping: A Case Study
Here's where technology steps in. According to both user experience and technical best practices, a significant portion of alignment errors—up to 47%—stem from improper hooping. When fabric slips or puckers during stitching, even the most advanced machine can't compensate.
