we have had a bit of a problem with the gantry we had to sqaure it up that went alright so we cut a job out now as we about to cut another one it goes into e-stopjust before it starts to do its first line, a error box comes up saying, Gantry skewing exeeds its limit. Bring up servo box for servo update. But we dont know wat to do in the servo box!
thanks

Gantry Skew
Tim, Mark, et all,
Gantry skew stems from one drive axis being more than .005 out (forward or behind) from the other axis. This only happens on machines with dual drives on the same axis. The most common cause is debri in the servo drive area that gets into the belt causing it to jump a tooth and be mis-aligned. However, it is also common to get this Gantry Skew error if you are normalizing the machine from several inches out of Home position. This is because during a normalize sequence the machine does not apply comp to the individual axis, so by the time the machine reaches home it may be skewed. But by the time it reads the home switch and jogs forward it is fine. So in this situtation that is a false error. Simply clearing it and continuing wth your program should cause no problems.
If you continue to have problems with this Skew problem please contact the Field Service Dept here at Thermwood and somone will be happy to help you.
Thanks,
