So today I fired up openbuilds control and it updated itself from 1.0.376 to 1.0.378. When I turned on my Lead 1515 everything seemed ok. When I connected to PC to the CNC the motors enabled light would go out and the motors were no longer locked. When I disconnect the light comes back on. Tried restarting the machine, the PC and nothing helped. I finally uninstalled the control app and reloaded the 1.0.376 version and everything seems fine now.
Go back to V1. 0.376 - download and install from OpenBuilds Software: OpenBuilds CONTROL and OpenBuilds CAM - FREE software to run your CNC, Laser, Plasma or Pen Plotter
