I just purchased a shopmaster cnc mill lathe combo. After initial setup mach 3 mill works perfect. I'm able to control all axis's. When I switch to Mach3 lathe I am immediately met by estop requested. I click reset and it will not leave the mode. Any help would be appreciated. Thanks.

Hi,
sounds like the lathe  Estop input is inverted relative to your mill profile.

Open your mill profile and on the Config/Ports and Pins/ Inputs page note whether the Estop input is either active high or active low.
Now open your lathe profile and confirm the its Estop input has the same setting as your mill profile.
