How to fix it
#1 Check the base plate and the riser base
If the detection screws on the base plate or the riser base (if used) are not tightened, the main control board won't pick up the signal. This will prevent the file from being sent to the machine, hence the error message. Please refer to this guide and check the screws.
Attention:
- Make sure the screws are of the correct type.
- Make sure the screws are tightened.
- You can use the spares of the same screw type in the package, or the longer ones.
#2 Unplug and replug the SD card
The S1 reads the G-code file on the SD card to do its job.
- If something's off with the processing status, the SD card is probably not working properly.
- Please power off the machine, remove the cover, and then unplug and replug the card.
For details, please refer to this video guide.
#3 Replace the SD card with a new one
If the issue persists, please replace the SD card. To get one:
- Contact customer support and tell us what happened. We may provide a replacement SD card for you.
- Or, buy one on your own if necessary. Make sure it's 32GB or smaller and formatted as FAT32.
For how to replace the card, please refer to this video guide.
#4 Gather information for further support
If none of the above solves the problem, please contact customer support and provide the following information:
- The log files from XCS.
- The log files from the SD card.
- The version of XCS and the firmware.
And tell us when did the issue happen. These will help us locate the cause. For how to get the above information, please refer to this guide.
