[grbl Issue#1256] can’t find the 4 axis pinouts for grbl mega 2560 anywhere About GRBL HAL

Issue #1256 | 状态: 进行中 | 作者: robogrow | 创建时间: 2017-06-26

I am pretty sure I have the 4 axis version of grbl loaded as it has $110 thru $113 values appear.

But I can’t find the pinout diagram for the 4 axises anywhere. I am testing the ports around 24 to 31 but can’t seem to find which pins are x,y,z,a step and direction.

Just look in the cpu_map.h file. It has all of the info you want.
