hoping someone can point me in the right direction. when i load my g code file in mach, it does not show the tool path for the part to be machined. sometimes you can see a very small L shaped line about the size of a pen tip on the screen, if you zoom in for like a mile, it will fill the display, but no tool path. this problem appeared after updating to version 2.2914. i ran as administrator to do the update. it may have nothing to do with it but that is when the problem surfaced. one thing to mention is that old g code files that i have seem to load just fine. when posting,i have tried saving them as tap and nc files. what other relevant info is needed? thanks in advance.
picture 1 is after loading the g code. only a small spec is visible on the screen
picture 2 is after zooming in a considerable distance
picture 3 is loading the roadrunner file (works)

Have you tuned, enabled and configured your motors and axes?
-
yes i have, i have been using the mill for several years. ill add a couple more screen shots and the machine profile if it helps
-
look at the history after loading, pic2 is showing bad character loaded that mach4 prob doesnt understand on line 19, perhaps this is stopping the toolpath from being created.

What version were you running prior to updating? You might want to try copying one of the default profiles and configuring it for your machine. The only thing I can think of that would cause what your seeing is a corrupted profile, steps per are way off, units (mm/inches) are not right or the units mode is not right (G20/G21).
-
i noticed the message about a bad character on line 19 but my lines go in increments of 10 so i am not sure where 19 is. machine setup units and units mode are both in inch. i see what you mean about steps per being off but if i mdi a 1 inch move with a dial indicator, it moves 1 inch on the money. is there some other files that would be helpful?
-
Yeah, you can open Mach, go to help, support package profile and attach the file you save it as.
If the line count is in increments of 10 line 19 will be labeled 190 (assuming line one is labeled 10 of course). Either way, line 19 will be the 19th line. I would get that sorted before doing anything else.

Double Click with mouse on the gcode window, this will bring up line numbers.

i thought i loaded the same program but it now says line 20 is bad

line 20 error

chaoticone, it will not let me upload that file

this is what i get

open your file in a txt editor and change to N180 (0.5INCH END MILL)

Thank you, it is fixed. i kept seeing that error message but did not know that double clicking the g code would bring up the line numbering as it did not coralate with the even N numbers on the screen. I realize that this had nothing to do with updating to the new software and is something that was changed in my cad/cam post. im not sure how or why i changed that but i did. thanks to all who offered help, i really do appreciate it.
