Maximum feed rate and how to change it

I previously saw a thread on the max feed rate of the machine set in the coding. Can anyone point me to this thread. Or fill me in. I would like to increase the maximum rate.

It is already set to 4000mm/min (157in/min) for X and Y. And Z is set to 3000mm/min (118in/min). That is about the max that the motors will run before having problems if I am not mistaken. I also believe they were originally set to 5000mm/min and this was causing motor issues.

If you want to see go to build instructions and look under Advanced and GRBL Firmware.
