Hi my fellow CTC users my x axis extruder block is slamming into the left side of the rail mount, any fix please

2

I would check the limit switch on the left hand side of the carriage - sounds like it may not be working.

Hi my friends, no the limit switch is ok, the extruder overshoots the plate when extruding the pre-print line, then skips a few notches on the belt when it reaches the end of the rods, then goes on to print fine.

I have also reset the printer factory settings, and re-installed the original firmware!

HI again my friends, the belt is tight but the extruder housing still overshoots the bed and crashes into the left end stop which does not have the limit switch, then the belt skips a beat or two and the head then goes on to print on the bed, it does not effect the printing of the object. If anyone has the technical knowledge of what is wrong I would appreciate their advice.
