Hi Am having a issue with the X axis on my GRBL CNC machine. Randomly the X axis stops moving at the end or start of a straight line. This only happens when running from gcode. Manually jogging does not cause an issue. It's not a slipping servo and I know it's not a skipped command because have of the command is done.
change your X max speed to half what it is now, and change the X acceleration to half what it is now. if that cures it then you may have had them 'just too fast' or you have some binding in the X travel somewhere. remove the motor pulley and move the carriage by hand and you will probably feel the tight spot. I had this with my X, everything could travel ok at 7500mm/min EXCEPT at the far end of X, in the last 6 inches or so it would hesitate. now I run it at 3500mm/min and it is always happy.
Thanks for the reply. After much mucking around and changing things. We swapped the usb cable, haven't had a problem since. Will keep monitoring it and will try your suggestions next.
