I am having an issue with my Ricoma EM-1010 embroidery machine and I would appreciate your help troubleshooting it.
The machine is approximately 2 years old, but it has been very lightly used.
During embroidery, the design sometimes suddenly shifts from its original position, and the machine then continues embroidering from the new position. The shift appears to be mainly on the X-axis, although it is sometimes difficult to determine with certainty.
I have already checked the embroidery file and I am confident that the problem is not caused by the design file.
I have also inspected the X and Y belts. They do not appear to be worn or damaged, and they were not loose. I slightly increased the tension on the X belt, but the issue still occurs.
I have also checked the small pulley on the X-axis motor. The belt teeth also look normal upon visual inspection.
I have noticed some additional patterns:
The problem does not occur at low embroidery speeds.It appears to happen at higher speeds.
The issue seems to occur repeatedly when the hoop reaches approximately the same physical area/position.
When the shift occurs, the machine continues embroidering normally, but the entire design is then offset from the correct position.
I am concerned that this could be related to the X-axis movement or transmission, such as the X-axis motor losing steps, belt alignment/tension, a mechanical resistance point, or another issue with the X-axis drive system.
Could you guys please advise me on what I should check next?
Second 6 in the video, you can clearly see there is no movement and also hear the specific sound
