Resume job after random disconnects

Hi,

Quite often my Shapeoko disconnects from my laptop. Unsure why this happens, is the USB connection very sensitive?

Therefore I often need to resume afterwards. I don’t know what percentage or line of gcode because it’s disconnected and information isn’t shown in Motion.

Is there any way to avoid this or resume? Does Motion create log files, so I can find out what line the error happens on?

To avoid this, address the EMI issue which is causing the disconnection — contact us at support@carbide3d.com and we’ll try to help.

Have you set your USB ports to not be powered down by Windows? This is the default setting in Windows to save laptop battery power, and is another common cause of USB communications loss along side of EMI issues that Will addressed.

Thank you. I’m looking at the wiki, but my g code doesn’t match up? What is my preamble?
