Shapeoko 2, GRBL version, and PWM

[LarryM]

I don’t know the differences between the Shapeoko 2 and the X-carve, but here’s what you would use if they are essentially the same.

Use Grbl version 0.9j

with 0.9j baud rate would be 115200 (it is 9600 with version 0.8).

with 0.9j
X home - D9
Y home - D10
PWM D11
Z home - D12
Probe - A5

with 0.8
X home - D9
Y home - D10
Z home - D11
Probe - A5

Here is one way to find out what version is on the Arduino. Write up is for 0.9j for 0.8 use 9600 baud

Using Grbl - Direct Communication

Direct access to grbl. You can interact with grbl directly to isolate problems at the low level. To do so, you need to use a terminal type program to issue commands and get responses from the serial port that has the Arduino attached. Some of the programs are HyperTerminal, Putty, UGS (limited access), and the Serial Monitor in the Arduino IDE, among others. Make sure that you have the correct settings for the program that you use. The COM port where the Arduino is attached should have the …
