I am glad to see that I am not the only one with issues with PoKeys and MPGs. The subject of feedrate override seems to be under-covered in the forum and the wiki. It is easy to get the signals to Mach but difficult to get Mach to do anything with them. I have defaulted to a pair of buttons for FRO increase and FRO decrease. Hard to do anything else without Modbus or a brain that I lack(literally and figuratively).
