Hallelujah, after waiting for exactly 34 days just for shipping, the PCB's arrived and I can finally make the CNC Controller again. Thank you for waiting.
Now with Grbl v 1.1e
This is my new version with small improvements, which are:
The pinout of the above screw terminal has it's GND changed to make it possible to connect it directly to my Stepper driver board, without having to connect the GND together.
3 Axis USB CNC Controller with Grbl 1.1e (latest version) with Step and Dir Outputs for each Axis
Because there is no other Controller with these features on the market. I wanted a Controller for my self build Vertical CNC Mill that can control high power stepper motor drivers. You can also connect the popular Pololu drivers to it or use my Phoenix Stepper Driver Board with it.
All the above features, plus it is meticulously hand assembled and soldered. If you look at the pictures you will see the quality of it. It is not a cheaply fabricated board. It uses free G-Code software and you can choose among many different ones. They support Windows, Mac and Linux. You don't have to buy expensive software like Mach3, which is very old and complicated to use and needs a Printer Port. My Controller connects to your USB port, that means you can use your laptop and don't have to have a dedicated PC in your shop. Create your design where you are comfortable.

I build the best Atmega328 based micro OLEDiUNO PCB that enables you to connect a I2C OLED display directly to the PCB. Plus the OLEDiUNO PCB features an on board navigation switch and 2 slide switches and or push button switches and 4 smd LED's in each corner front and back, totaling to 8.
Also build the best Grbl based CNC Controller with PWM output, spindle enable and coolant outputs among other features not found on any Arduino shields.
