CNC Spindle stopped spinning mid cut and wont start up again

I have an A350 that I’m using to route out some small wood pieces. It has been working find but the spindle just stopped randomly during some adaptive clearing. I stopped the program, restarted the whole machine and it still won’t start the spindle.

The spindle is much harder to turn by hand than before. Any suggestions?

I had issues with the CNC and ended up swapping out the head for the 3d printer and when I went back to the CNC it worked fine again. Turning off and on the machine didn’t clear it but swapping out the head did. Worth a try…

Export the logs and share it here.
If there is too much counterforce the spindle detects a block and wont start again.

I tried this but it didn’t change anything. Based on a suggestion from another forum, with the spindle disconnected from power, I shot compressed air up the spindle shaft on one side while spinning it manually. This seemed to have dislodged some dust/debris that was inside the spindle and allowed to begin spinning as expected. Once reconnected everything seemed to work well except for the odd twinging sound. After allowing the spindle to run for several minutes with the compressed air being blown as before, everything returned to normal.

This suggest, there was just some dust inside of the spindle (the actual motor part not the housing) that was causing too much resistance. Once cleared out, everything returned to normal.

There is a toolhead information command where the error should be detected: M1006

Have a look at the details here:

Great the cleaning out did it for you!
