xTool S1 with the RA or Convoyer Feeder.

Issue description

When using the S1, if you encounter no issues while processing in flat mode but experience rotational stuttering with the rotary attachment, or stuttering in the forward and backward movement when using the conveyor feeder, please follow the troubleshooting and resolution guidance provided in this document.

How to fix it

Before troubleshooting, let's ensure all accessories are connected to the correct ports.

1) For the air assist and fire safety set, the ports are on the rear connection board.

2) For the rotary attachment and the conveyer feeder, the ports are on the front connection board.

#1 Check the accessories' movement by hand

If the rotary attachment or the conveyor feeder is faulty, it may not move smoothly when you move them by hand. We'll use this to tell if there is an issue and then fix it.

1) Power off the S1 and manually turn the rotary attachment or push the conveyor feeder. If it's jammed, replace it. If not, move on to the next step.

2) Power on the S1 and do the same thing for the attachments. If it's jammed, replace the connection cable.

If the issue persists, move on to check the next part.

#2 Check the rear connection board and cable

1) Disconnect the air assist and the fire safety set to see if the stutter persists during the operation of the rotary attachment or feeding accessory.

2) If everything is back to normal after the disconnection, refer to this video guide to remove the mainboard protective cover and check for any deformities in the three ports of the rear interface board. If deformities are present, a replacement of the rear interface board is necessary.

3) Proceed to disconnect the rear interface board located next to the mainboard. After disconnecting, observe if there are any abnormalities during the operation of the rotary attachment or the conveyor feeder.

4) If it's back to normal after disconnecting the rear interface board next to the mainboard, then there is an issue with the rear interface board or the connecting cable. Replace the rear interface board first; if problems persist, replace both the rear interface board and its connecting cable.

#3 Check the front connection board and cable

1) Please follow the instructions in this guide to remove the outer casing of the S1.

2) Examine the front interface board's connecting cable for any signs of damage or breakage. Should there be a break, it is necessary to replace the front interface board's connecting cable or exchange the machine.

If the connecting cable of the front interface board is intact, you may attempt to replace the front interface board and conduct further testing.

#4 Replace the main board

If you have done everything above and the issue persists, you may need to replace the main control board. For details, please refer to this video guide.
