Assuming you are using the Axis GUI, you scroll down to the line you want to start from, using the mouse buttons on the G-code window. You click to highlight that line, and then in the File pull down (I think) is a "start from line" entry. Click on that, then hit "r" and it will run quickly through the code to get to the right position and modes at the beginning of the selected block. BUT, it won't start the spindle! If you don't have a manual spindle override, you are pretty sunk until this BUG is fixed. Starting the spindle with F9 and then doing the Run will just turn the spindle off.
Please excuse, I'm going into <rant on> Clearly, the spindle is a modal operation, just like G41 or G17, and so if the G-code starts the spindle in the first couple lines, it should be running when the line to start from is performed. In all machining operations, you'd want the spindle to be started before beginning a cutting operation. If somebody used M03 and M05 to turn a plasma cutter or laser on and off, then these would be scattered all through the code, and presumably the operator would know to start on a line where the device was off. This all combines with spindle speed, and maybe even gear changes, so it might get a bit more complex. But, these are clearly modal functions, and so if you are preserving the state of all the other modal settings, spindle on/off and speed should be handled as well. <rant off> Jon ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
