I just tried a test move of G93 G0 X100 F0.01 and it moved 1mm in 1 minute. > rotating A axis with something like G93 A45000 Z-1 F.2. I tried this G-code in the axis-9axis sim. It complained that there was no movement mode active. Putting in a G1 I got approximately the expected result, in that Z moved 0.5mm in 4.5 minutes. So I assume that the A axis was maxed out in the simulator. Bumping up the A axis max speed from 90 to 360 gave me a system that did 25 revolutions in 1 minute. Had you done a G0 move? G0 X0 Y0 G93 A45000 Z-1 F.2 Moves very fast. As G0 is modal. This ought to be an error, I think. (G0 X0 Y0 F10 is accepted. It is valid G-code but probably isn't what anyone intends. It says "set the feed rate to 10 and then perform a rapid move") G93 with G0 active, however, clearly makes no sense and appears to cause confusion. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
