How can I make the tool just rise above where it ends instead of -10 for all? Not sure what post processor I'm using, probably the latest. Looks like it's something in Group 5 or 6 in Fusion. Thanks
Are you using the Openbuilds post processor? docs:software:fusion360 [OpenBuilds Documentation] That uses the machine co-ordinates system to raise Z to a safe height (default -10, 10 mm below the homing switch) and you can change that setting in the post processor. Sorry, haven't got Fusion on this PC or I would show you a screenshot, but the thread below might help. Excessive Z axis retract Alex.
Yes, Openbuilds post. The Z is good at -10, it's the X,Y. I don't want the machine traveling all the way back to -10,-10. Just raise the Z -10 and stop where the program ended.
Options are, carry on using machine co-ordinates (G53) and choose the coordinates where you want to park it at the end of the job, or untick "use G53" and set coordinates in the workplace coordinates system (eg X0 Y0 and Zn where n = a positive number that will raise Z above the workpiece but still not hit the limit switch). The reason the default is to use G53 is that is a definite position in the machines workspace, but the workplace coordinates system depends on where you set the workplace zero - if you change the workpiece you might forget to change the settings in the post processor and give yourself a problem if you run out of space in the Z axis. Alex.
Correction. Unticking "use g53" only effects X and Y. Z will still use G53. That's why Z says (MCS only).
Further details. If you hover your mouse over "Use machine coordiates....." you'll get the the following description: "Yes will do G53 G0 x{machinehomeX} y(machinehomeY) (Machine Coordinates), No will do G0 x(machinehomeX) y(machinehomeY) (Work Coordinates) at end of program" If you hover your mouse over "End of job Z.." you'll get the following description: "G53 Z position to move to in Millimeters, normally negative. Moves to this distance below Z home."
