Hi guys, this is my first post so pleas be easy on me. So here's the problem - i have made a driver for my motors (unipolar, 6V 1.2A, 1.8 degrees step) and i use the TurboCNC to drive them. Everythng works fine when i start the program - the Gcode is been read and sent to the port, and the motor (currently only for X ) is moving. Here comes the strange part - when i move the mouse while the program is running the motor seems to be decreasing it's sped (loosing step). The faster i move the mouse the more obvious the problem becomes. I am using an 750mhz 256ram computer. So the question is what is going on, and is the motor really loosing step, or the software is just "freezing" for a moment, not sending a pulse to the port and after that continuing it's normal operation ?
Sorry for the english guys.
