1. If you are using the Red Cap Frame Driver, check the Ball Bearings Adjustment or other binding points.
2. If you are using the Melco Fast Clamp, it might be hitting the lower arm. Remove the Melco Fast Clamp from the machine before continuing with the steps below.
3. Write down the current Stitch Count and X/Y Position.
4. Cycle the Emergency Stop Button.
5. Try to Trace.
6. Remove the Hooping System from the machine. This includes the Hoop and Fabric, Hoop Arms or Driver, or Clamp.
7. Power Cycle.
8. If you do not get the error, it is likely the Hooping System was causing a Physical Bind. Reinstall the hoop and check for any other binding. Do not trace without a hoop.
- The X-Carriage is hollow to allow fabric to be tucked into it. This helps prevent binding underneath the carriage.
- This article has tips for Heavy Fabrics.
- Verify if the hoop is hitting the Lower Arm.
9. If you do get the error without the Hooping System, continue with the steps below.
10. Push in the Emergency Stop Button.
11. Compare the movement to another machine first if possible. Move the pantograph by hand all the way left and right. The movement should feel smooth, it should not bind. If it feels like a physical bind, do not force it. Check the X Cable for damage and if it’s around all Pulleys PN: 30952-03.
12. Check the 3.5" Optical Switch Assembly PN: 30704-03 for grease or damage.
- Remove the 34537 Upper Arm Left Side Cover
14. Turn the machine OFF.
15. Reseat the Rainbow cable PN 30193-04 on the Main-PCB and 31066-01 XY Home PCB Assembly.
16. Check the Sensors Menu.
- See Understanding the Sensors Menu.
17. Reflash the Main-PCB.
18. If possible, swap the Main-PCB with another machine. If the error does not appear the Main-PCB might need to be replaced.
19. Replace the Rainbow cable PN 30193-04.
20. If the situation remains unresolved, you will need additional technical assistance. Here are the available Melco Technical Support options.
- Check the X Motor.
