Hi ,Rich

i got it under control but it is still not clean ,just a slight move. had to set shuttle speed to the bar bone and open and close mach a few times so it would catch.i never noticed it running
small dia parts . with a 18 inch dia part it is a big problem. well back to the grind,thanks.

General Mach Discussion / 4th axis ghost move

« on: November 11, 2008, 12:56:30 PM »

using mach3 ver 2.02 and ver 3.042.016  -- using no CV and no backlash!
below a code snippet. -- mach3 adds a move between the lines of code before execution.

g00 x-1.9375 y0 a0
g01 z-.100 f5
         (then Aaxis makes a move 0.050)
g01 x-.0625 y.125 a90 f7.0
g02 x-.0625 y-.125 r.125
          ( then A makes a move 90.2167)
g01 x-1.9375 y0 a180
          ( then A makes a move 180.050)
g01 x-.0625 y.125 a270
g02 x-.0625 y-.125 r.125
          ( then A makes a move 270.2167)
g01 x-1.9375 y0 a360

the Axis is suppose to move from 0 to 90 not 0 to 0.050 then to 90 .
it is adding a extra move before it executes a line of code that includes the 4th axis

it looks like you have to close JP6 when you use USB power.double check the manual.

i use lcam a bunch for many differant project targets including my 4th axis. mach supplies you with scale and text editor tools. combine with this lcam and a couple of free cad programs,throw in a little longhand g-code with a little imagination.add a little understanding . all this makes a pretty powerfull toolkit.
