I think that im first that modified grbl from bipolar to unipolar https://github.com/costycnc/costycnc-costycnc-grbl-1.1-unipolar and another repositories ... because i see that my modified files with some my variables is used and preluated by many coders ... but any specified my name costycnc ... i hope that some coders include also my name ... because im first that i changed the original code,,, thanks!

for sure you will have your name credited, I didn't know it had your code, I forked the robottini code
