Describe the bug
I'am using TTC450 with 500W spindle. The G-Code of sensor.ncc is sent to the machine.
If the spindle is not attached or powered of, the G-Code is completely transferred and
the visualization is shown as expected.
With spindle attached and power on, the G-Code is completely transferred and executed,
but the visualization stops after the command M3 S12000.
After completion of the job, candle has to be reset.

Working with the 80W-spindle does not produce this error.

Maybe the reasen for freezing of visualtion is the response after sending M3 S12000 ?
Seems to be some not recognized garbage ?

To Reproduce
Steps to reproduce the behavior:

1. Use TTC450 with 500W spindle, connected and powered
2. Load sensor.ncc in Candle
3. Send the G-Code
4. See G-Code log

Expected behavior
the garbage message should be ignored, visualization not frozen, candle working without any errors
