General Mach Discussion / ShuttlePro startup
« on: November 28, 2009, 12:41:52 PM »
Is it possible to set the "startup state" or default state of the ShuttlePro functions?
I'd like it to be locked and have z jog at startup

Thanks

Don't know anything about VectorCam, but is there a setting to "roll around corners"? That gave me fits in MasterCam, until I found about it

General Mach Discussion / Re: changing feed rate during direction changes
« on: October 22, 2008, 10:42:47 PM »
Joe,
No, cutter comp has nothing to do with feed rates. It is used for:
A: allowing you to program to the centerline of the spindle and then put in the radius of the tool used to properly position the tool, or

B: adjust for tool wear or for an undersize tool when programmed to the edge of a known diameter tool

Some CAM programs will adjust the feedrates for you, slowing it down for an inside corner, and speeding it up for an outside corner, the idea that the feedrates to the edge of the tool (where it's doing the cutting) will be different from the centerline of the toolpath as programmed

Go up a few posts and look at the graphic. Where it has the G80, add G90 and anything else you might need and then check box above that says "use INIT string on all resets". That should do the trick. Mine, for example has G80 G90 G49 G0

Maybe try putting a G40 in the "all resets" line in general config?

General Mach Discussion / Re: Command to move Z-Axis -0.8500?
« on: September 29, 2008, 08:32:41 PM »
G90 is absolute mode (will move to a certain position no matter where it starts) and G91 is incremental mode (moves a specified amount in a specified direction) so...
G0 G91 Z-.85 will move the z down .850". If G91 is still active G0 Z0 will do nothing (it's telling it to move 0") If G90 is active G0 Z0 will move the z to the position of z0.
Normally programming is done in absolute mode with incremental used for more specialized things

G0 G91 Z-.85 should do it
make sure to do a G90 after it it's not in the program
