General Mach Discussion / Touch plate problems and accuracy
« on: December 16, 2017, 07:25:31 PM »
Hi all. I need some help. I have 2 touch plates. 1 corner finder which works great and 1 fixed touch plate. The fixed touch plate, the tool rapids down and hits the plate, stops but does not retract to slowly come Dow for a second touch off. I have to reset mach3 and manually retract it. Does anyone have any suggestions or ideas what is happening as the corner finder works as it should. 
The other issue I am having is my machine measures correctly near the home switches but but no where else.

General Mach Discussion / Double cuts
« on: March 17, 2017, 06:10:44 PM »
I wrote a gcode to do some.5 dia holes and some.25dia. When mach3 cuts 1 hole out it does it again for no reason. I checked my card and it say it does 6 passes per hole where mach3 is doing 12. Why do I have something set wrong. Another thing it is doing is not cutting the holes out to the proper dia they are about .013 undersized. I checked all my axis for Cal and set my back lash but it's still there.

General Mach Discussion / Big trouble
« on: January 06, 2017, 08:14:27 PM »
Hi all. I am new to the cnc but my limit switch keeps tripping every 10 seconds approximately.  Even though no axis is even need the limit switches. So I go to the diagnostic screen and nothing is lit up. I then go to con fig /pots&pins/input and start x ing the limits until I stop getting the limit warning. It seems to be in the y axis and I don't know why I am getting this all of a sudden for no reason. Can anyone help me I'm out of ideas.
