machine was operating successfully yesterday. on start up today, i cannot get the machine to home properly. go thru the steps, power up, e-stop reset, jog x-, z-, press home key, then z+, x+, machine only jogs in each axis the time you hold z+, x+. it doesnt auto home, if that makes sense... i have tried restarting it many times with collet open, collet closed, bar feed active, bar feed not active. i have manually moved into overtravel in both directions, restarted repeatedly, checked lubrication levels.... on and on... i bought the lathe brand new in 1986? been using it since, i am not highly technically trained, but i find my way around ok...
