If removing a space character changes the behavior, please file a bug report. Spaces are ignored in gcode, except within a comment. Come to think of it, there is another case where removing a space character should change the behavior. If the original line was too long and removing the space ma

Dirk, What you are seeing is the waypoint function of G28. G28 X5 Z5 will move to X5 and Z5 from the present position then move to X0 Z0. This is for obstacle avoidance. G28 will always end up in the home position. John On 22 Jun 2008 at 14:06, John Thornton wrote: > G28 goes to a predefine

G28 goes to a predefined position (home as defined in parameters 5156-5166). To make G28 go to 0,0,100 you must home the machine there which will become 0,0,0. Then a G28Z0 with no space will home the Z axis only. The space between the G28 and the axis must call up an undocumented feature... J

Hi all, well, just deleted my question. When double checking all the facts, reproducing the problems, I got some clue about what was going wrong. But there is still 1 thing unclear. My postprocessor, NX5, made with postbuilder, automatically adds a G28 at the start of the program. Since I have a ve
