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.

What xml file are you talking about.

You will find the xml file that you are using in the Mach3 directory. The first part of the file name is the profile name you
use / select when Mach opens. IE; router.xml

I also was thinking that there may be a soft limit setting problem.
