need help from experts. I need to build small CNC for school study purpose, and have minor problems with driver.
Current situation of hardware, and software:
- Arduino Uno
- stepper motor EasyDriver v4
- Nema17 stepper motors
- github grbl open source as software
I have already successful hardware, with grbl software. Process works successful.
What I have found that EasyDriver are very unstable, meaning they are overheating, sometimes one of them is not even working (like disconnected at all). I have also already find some public posts that also other users have same problems.
So, what I would like to replace those drivers. Most would like to build own circuit, but do not have a lot of experience with IC chips which would able to connect with Arduino, and to be compatible with GRBL software. Of course I can buy something for 50-100$, but that would not be a student project anymore, due to high cost budget.
