ok, i am very new to this and have 2 homemade cnc routers. i had someone here today checking computer settings and plug ins because of intermittent job interruptions, dont think we changed anything but must have.
we are using mach 3 with ess smoothstepper, gecko 203v drives, nema 34 stepper motors. the machine jogs as normal. because it is a large machine i usually jog it to within an inch of the home position and then home it. when it goes to home the y axis only one motor is turning causing a bad noise and misalignment of the gantry. also, when i shut down mach 3 it has always asked me if i want to end session-yes. it would then ask if i want to fixture save-yes. well, it is not asking about the fixture save now either. any help is very appreciated as i have no support from the man that built the machines. thank you, db
