It may be only me but I find it easier to control everything with the keyboard. With the mouse you always have to find it's position first, if it's a optical mouse you have to wake it up first, you have to stand in-front of the monitor or you have to be coordinated to work the mouse from the side of the monitor (I do it some times but it's kind of not intuitive). I would rather go with a servo controller. They are about $3 shipped from China and I have an instant a positive control. By the time I got the speed changed in Mach3 (or EMC) I have the spindle already controlled and running with the servo controller.

Just my :02cents:

 

PlanetCNC users already have this integrated in their controller

It is still beta and I only tested it with servo motor. I plan to fully test this with ECS and brushless motor before I'll publish next software version.

Check "Settings/tab Outputs/Use RC Controller" and pin assigned for speed will produce servo compatible signal. Be aware, that you can not use same 5V to power servo motor and controller. Voltage drop can cause controller to reset. Using separate power for servo works fine. Like I said - I didn't try with ESC and BEC.

 

Perhaps I wasn't clear enough - this in only in BETA version of software. You can get it on my web site.

And if somebody is willing to test this it will save me some time.
