hello

so im new to mach 3 and to the whole cnc router thing (more of a 3d printing guy) and iv been working on my cnc router for about a year now (1.6m x 3m bed) and i use a large gantry system power by two 20nm stepper motor hybrids with separate drives connected to a galil 4080 but the problem is i have got the x and a axis slaved together which is working as they home together but how can i jog the master and slave axis together at the same time?

thanks for your time and help
