reprap on winxp with gen6 and java sw
I am using the reprap java sw to try to run a newly assembled gen6 mendel.
I can succesfully save gcode from stl files. when i load these and try to print however i get an error such as
error: AllSTLsToBuild.remove(): removing an item from a frozen list [919.718s/-1310300882985ms]
also moving the head manually e.g. with the 'xyz' controls doesn't seem to do anything...
i tried using jre 5 instead of jre 6, as well as setting the java environment variable as at http://reprap.org/wiki/Installing_RepRa ... r_computer
but no dice. any suggestions
