General Mach Discussion / x axis problem
« on: January 23, 2015, 09:07:50 PM »
I have a cnc router the name of the company I purchased it from is Industrial CNC. I have had a few problems in the past and have figured them out. The problem that I have now is with the X axis. It works fine until it moves about 3 feet left to right on the gantry. At this point The gantry stops. Always at the same point of travel. I have checked the gears, motor and slides. I have removed the motor of the x axis it turns in both directions. When the x gantry stops the DRO  numbers continue moving

Now this makes no scene to me the motor,not attached to anything, turns freely that would move the gantry to the left. If I switch direction, movement to the right, it turns freely but after several seconds , maybe longer, it stops turning. The motor is NOT attached to anything and it still stops when it turns , from what would be left to right.

I can manually move the X gantry either left or right with nothing binding in either direction. I can use the cnc and it works but I can not use the full travel of the x axis. Attached are the specs of my machine. Does anyone have an idea of what maybe happening. I have also switched the cables of the x and y axis. With the y cable controlling the x axis the problem still remains . the x gantry stops at the same point of travel.
