You can better remove the CPU board and replace it by a adapter board of axemotion and the pulsebox
NxtG. Your profiler is than full 3D not 2,5D like the profiler CPU. It can be driven by GALAAD software. If you need the gerbers for the adapter PCB contact me. I have also a few PCB to buy. Professional made by PCB pooler. With silk, and component print.
The profiler runs smoother and faster with the pulsebox galaad combination.
The pulsebox have the possibility to connect a tool length switch and a 4the axis with his own driver like a geko or leadshine.
