the boss has me making a tic tac tow set out of 3/8 ply wood

i cut out the thing untill one of the last lines then it just resets the zero and goes off from the new zero there is no command being used to do this

and it does not repeat it the same every time so far the 2 times tryed one time moved the y axis about 9 inches the other time moved it around 4 inches


Also for note in case it maters the IJ mode is set to absolute and the distance mode is set to absolute this is because of how our prints are made this way seems to work best

Please attach <your profile> .xml file -  the one from the Mach3 folder (typically Mach3Mill.xml). Copy and rename it to Solosys.xml and use the Reply tab and Additional Options to attach to your post. This file contains your machine settings and may throw some light on the problem.

there you go

Your Gcode runs (using your .xml settings) just fine here and without any error. You appear to be using a rather old version of Mach3 - I am not certain that updating to a later version would make any difference but it is worth a try (use version R3.043.062 rather than .066).
