I had a belt slip yesterday during cutting, this caused the router to go awol, i fixed the slipping belt issue however it has raised allot of concern. Is there any way of the error such as this being detected and activating an estop automatically? Say monitoring the current through the motors and have any spikes caused by excessive resistance activate an estop. Also can you help, what is the best way to resume the job in such event? (Mach 3) once the machine has been fixed and axis re calibrated that is. Obviously mach 3 will need re zeroing but is there any way to continue from just before where the job ran into trouble?.. this particular job has 18,000 lines of gcode so scrolling through to find the last position would be horrendous. thanks.
