If the job is abruptly ending prematurely, the issue is most likely EMI (noise on the USB cable). This is a common issue that people have.
Here are are few things to look at:
- Ensure the USB cable is routed away from the power cable for the router as much as possible.
- Plug the router into a separate circuit if possible.
- For each stepper motor cable, if you have the shielded cables, expose the shield (foil/wire or both) from each cable at the end connected to the X-Controller. Tie/Connect these ends together and connect them to one of the GND pins on the X-Controller. Leave the ends at the stepper motor disconnected completely.
Search the forum for other things to look at because there have been a myriad of posts about this issue.
When this happens during a carve, you can also click the link that says the carve did not go well and then select get help from Inventables. This causes Easel to send Inventables a trouble-ticket with a diagnostics file. They might be able to confirm is the issue is a communication issue.
