So, finally got machine built , a 3 axis Gantry router using 4 motors forth motor as " A " axis slaved to y axis ,bought licence for Mach3 and started to install, all went well till tried ref home. only the motor on the y axis turned , the slaved A axis does not, a quick E stop saved any damage, try to fix this has had me pulling my hair out !
At one stage i had motors going in wrong direction; one side of gantry moving forward while the opposite side went back! and a constant E stop condition!
I Know am at the stage were z homes but does not retract from home switch and only the Y axis turns !????! HELP.
