Greetings!

Great job on the firmware!

I was wondering if you will implement servo rate(speed) and engraver commands? I am trying to do some engravings and the pen down speed can not be controlled, I looked the arduino sketch but can't find any implementation of rate adjustment!
Also I have built a micro engraver with a small rc plane esc/motor and would like to have a way to turn it on and off and control the speed with a pwm pin!
I am a RC enthusiast and have been for many years! I also am an electronics tech!
If you have any questions that I might be able to help you with configuring the firmware just let me know!
I wish my arduino code skills were as equal to my electronic skills! I praise people who can write code like you do!

Sincerely,

Greg
