I currently have a machine that uses a combination of a Mesa 7i92TM and 7i77. But all axis outputs are used and I need another axis for a toolchanger. I want to use a 7i76U for step/dir controlling a servo. Can I use the 7i92t_7i77_7i76d.bin for this or is the 7i76U a different board? If I need an other .bin file, can someone make it for me?
