How to set the maximum speed at 20,000 rpm?

[viewsat]

Hi jmharvey1,
Can you set the maximum speed to 20,000 rpm?
Because my spindle to a maximum speed of 18000 rpm.

The Sketch, as written, limits the top end to 10,000 RPM. That’s because the spindle motor and power source I used maxed out at about that speed. If your machine is capable of 20K, then you can modify the sketch’s maximum to read 20,000 RPM. Will it work at 20K? I can’t say. In principal it should, but a lot will depend your actual setup.

Search inside the exmaple this line "if (trgtRPM <10000) " , 10000 is the max speed" , change by 25000 for example
