I can’t get my OLM3 to home. I get the error:8 Grbl $ command cannot be used unless Grbl is idle. I have tried resetting, a different USB cable It has happened before but it reset itself. I am looking for some suggestions to get it moving again

Thank you

Try clicking on the “Stop” button in LightBurn first - then the Home button.

And check out this post also which discusses a couple of potential causes;

I’m constantly getting Grbl ‘$’ command cannot be used unless Grbl is IDLE. Ensures smooth operation during a job. Error:8 I get this error only when cutting leather at 75mm/min and 100% power. Etching leather at 3000mm/min 40% power doesn’t produce the error. Log attached, any help would be appreciated! Error_8_Log.txt (919 Bytes)

Nicholas,

Thank you for pointing me in the right direction. I thought it was a power issue so I swapped out the USB cable and the power supply and the unit returned to a working unit again. WE are back Lasering again.

Thank you
